You know Memorial Days 18 00:00:57,840 --> 00:01:00,520 Speaker 2: coming up, right, because there's a couple of things I 19 00:01:00,520 --> 00:01:02,720 Speaker 2: didn't touch on in the last show, and you know 20 00:01:02,800 --> 00:01:06,680 Speaker 2: it's it's it's sort of simple conversation, right The issue 21 00:01:06,959 --> 00:01:09,920 Speaker 2: is we all look for faults when they occur. We 22 00:01:09,959 --> 00:01:13,679 Speaker 2: don't look for preventative things. We assume if there's no 23 00:01:13,800 --> 00:01:17,920 Speaker 2: check engine light on the car is good, and that's 24 00:01:17,959 --> 00:01:20,840 Speaker 2: not true. You know, fuel trims can drift a little bit. 25 00:01:21,040 --> 00:01:27,240 Speaker 2: There can be problems with the evaporativision emission system. For example, 26 00:01:28,800 --> 00:01:30,959 Speaker 2: if you always fill your car up at the three 27 00:01:31,040 --> 00:01:37,160 Speaker 2: quarter tank mark, you will never ever set an evaporative 28 00:01:37,200 --> 00:01:41,880 Speaker 2: emissions fault code. Did you know that? And the reason 29 00:01:42,080 --> 00:01:45,679 Speaker 2: is because the EVAP monitor. The self test for the 30 00:01:45,720 --> 00:01:49,000 Speaker 2: EVAP monitor runs at three quarters of a tank or 31 00:01:49,080 --> 00:01:51,560 Speaker 2: between three quarters of a tank and a quarter of 32 00:01:51,560 --> 00:01:54,520 Speaker 2: a tank. So consequently, if you're the other way around, 33 00:01:54,560 --> 00:01:56,560 Speaker 2: if you're putting in three dollars well let's make it 34 00:01:56,920 --> 00:02:00,000 Speaker 2: five dollars a trip a gallon every time you take 35 00:02:00,040 --> 00:02:01,560 Speaker 2: take the car out, because you go down to the 36 00:02:01,560 --> 00:02:04,120 Speaker 2: corner store and there's always less than a quarter tank, 37 00:02:04,160 --> 00:02:06,160 Speaker 2: it'll never run the EVAP monitor. So you cant have 38 00:02:06,160 --> 00:02:08,840 Speaker 2: a problem with the evaporative emission system where it's venting 39 00:02:09,240 --> 00:02:13,000 Speaker 2: fuel and fumes over the time, that's gonna cost you 40 00:02:13,080 --> 00:02:18,200 Speaker 2: fuel economy. Maybe the thermostat's running cooler now, depending upon 41 00:02:18,240 --> 00:02:22,040 Speaker 2: how you're driving. That thermostat fault code may not come 42 00:02:22,120 --> 00:02:27,320 Speaker 2: up so quick, so you may use more fuel. And 43 00:02:27,520 --> 00:02:29,639 Speaker 2: maybe once in a while a wheel speed sensor is 44 00:02:29,720 --> 00:02:33,600 Speaker 2: dropping out and it's affecting the way breaking operation occurs, 45 00:02:33,600 --> 00:02:40,280 Speaker 2: affecting actual calculation of vehicle speed. So the point is, 46 00:02:40,440 --> 00:02:44,320 Speaker 2: if we're looking for fuel economy modern cars, you know, 47 00:02:44,639 --> 00:02:46,240 Speaker 2: they're like that walk in the woods. 48 00:02:46,560 --> 00:02:46,720 Speaker 3: Right. 49 00:02:47,160 --> 00:02:49,480 Speaker 2: Was it Hansel and Gretel that dropped the breadcrumbs along 50 00:02:49,480 --> 00:02:51,200 Speaker 2: the way and to find their way back? I think 51 00:02:51,240 --> 00:02:53,720 Speaker 2: that was a different fairy tale, But you get the point. 52 00:02:54,480 --> 00:02:58,400 Speaker 2: Memorial Day weekend is coming up, and it's a great reminder. 53 00:02:58,440 --> 00:03:01,240 Speaker 2: It's a great opportunity to say, pay attention to your 54 00:03:01,320 --> 00:03:04,000 Speaker 2: vehicle now when instead of on the side of Interstate 55 00:03:04,120 --> 00:03:07,400 Speaker 2: ninety five with the family staring at you, especially going 56 00:03:07,560 --> 00:03:11,400 Speaker 2: I told you this is the unofficial start of summer 57 00:03:11,480 --> 00:03:14,600 Speaker 2: driving season here in America. Right, we're loading up the SUVs, 58 00:03:14,680 --> 00:03:16,720 Speaker 2: the coolers are packed, the kids are going. Are we 59 00:03:16,720 --> 00:03:20,720 Speaker 2: there yet? You haven't even left the driveway. Everybody's heading 60 00:03:20,760 --> 00:03:22,839 Speaker 2: somewhere at once. And trust me, this week, we could 61 00:03:22,840 --> 00:03:25,680 Speaker 2: see the traffic in New Jersey was just getting bad. 62 00:03:26,720 --> 00:03:30,120 Speaker 2: Check your tire pressure. Check the spare. Look at the battery. 63 00:03:30,120 --> 00:03:32,560 Speaker 2: If it's older than four years, you know what are 64 00:03:32,560 --> 00:03:35,760 Speaker 2: we waiting for? Okay, If it's an AGM battery, put 65 00:03:35,800 --> 00:03:38,080 Speaker 2: an AGM battery back in it. If it's a standard 66 00:03:38,080 --> 00:03:41,080 Speaker 2: flooded battery, put a standard flutter battery back into it. 67 00:03:41,360 --> 00:03:43,600 Speaker 2: Put what's Put the right battery into the vehicle. If 68 00:03:43,640 --> 00:03:45,640 Speaker 2: you're trying to pick a battery, get out to auto 69 00:03:45,680 --> 00:03:48,920 Speaker 2: Batteries dot Com and read about it there. Look at 70 00:03:48,920 --> 00:03:51,960 Speaker 2: the wiper blades. You have your peak wiper? Do you 71 00:03:52,000 --> 00:03:53,880 Speaker 2: have your peak wiper blade? I gotta said a peak 72 00:03:53,920 --> 00:03:55,880 Speaker 2: wiper blades. I put them on the plow truck this week. 73 00:03:56,200 --> 00:04:00,680 Speaker 2: Oh my god, it's like night and day. Look at 74 00:04:00,680 --> 00:04:04,160 Speaker 2: your fluid levels and listen. If the check engine light 75 00:04:04,320 --> 00:04:07,320 Speaker 2: has been on since Valentine's Day, maybe you know you 76 00:04:07,400 --> 00:04:09,280 Speaker 2: got to stop hoping it's going to fix itself. We're 77 00:04:09,360 --> 00:04:13,120 Speaker 2: about to start the summer driving season. Cars don't. Cars 78 00:04:13,160 --> 00:04:17,000 Speaker 2: do not heal emotionally. They just don't. They don't magically 79 00:04:17,080 --> 00:04:20,760 Speaker 2: fix themselves sometimes short term, but nothing's going to ruin 80 00:04:20,800 --> 00:04:24,719 Speaker 2: the upcoming holiday weekend faster than standing on the shoulder 81 00:04:24,720 --> 00:04:26,680 Speaker 2: of the highway of filling your family. Well it didn't 82 00:04:26,680 --> 00:04:28,480 Speaker 2: do it yesterday. Well, but you had two weeks to 83 00:04:28,520 --> 00:04:32,240 Speaker 2: get ready. Meanwhile, steam's coming out from under the hood. 84 00:04:32,360 --> 00:04:36,000 Speaker 2: You know what. You guys spend more time organizing the 85 00:04:36,080 --> 00:04:39,359 Speaker 2: cooler sometimes than preparing the car for the trip. So 86 00:04:39,440 --> 00:04:41,840 Speaker 2: if the sandwiches are organized and the beach chairs are 87 00:04:41,880 --> 00:04:44,680 Speaker 2: packed and the dog has snacks, the car deserves a 88 00:04:44,680 --> 00:04:47,279 Speaker 2: little love too. Just just get ahead of it now 89 00:04:47,600 --> 00:04:49,919 Speaker 2: while you can. I'm ronning ay in the car. Doctor. 90 00:04:50,000 --> 00:04:51,520 Speaker 2: Let's go and open up the phone lines. Let's go 91 00:04:51,520 --> 00:04:54,520 Speaker 2: over and talk to George and Alabama nine Toyota Ta Coma. 92 00:04:54,760 --> 00:04:57,040 Speaker 2: See what's going on here? George, Welcome to board, sir. 93 00:04:57,040 --> 00:04:57,640 Speaker 2: How can I help? 94 00:04:58,680 --> 00:05:01,320 Speaker 4: Oh yeah, let's see. Of course you said it two 95 00:05:01,400 --> 00:05:03,440 Speaker 4: thousand and nine to comea with a two point seven 96 00:05:03,560 --> 00:05:06,720 Speaker 4: fourth cylinder about one hundred and ninety one thousand miles. 97 00:05:07,279 --> 00:05:10,080 Speaker 4: A couple of weeks ago, check engine light and attraction 98 00:05:10,200 --> 00:05:14,480 Speaker 4: light came on, pulled in and had it diagnosed, and 99 00:05:14,520 --> 00:05:16,840 Speaker 4: it said it was a misfire on number two. Too 100 00:05:16,920 --> 00:05:20,640 Speaker 4: many misfires, I guess the whey they read it. So 101 00:05:20,960 --> 00:05:24,400 Speaker 4: I went, well, go to the internet. What's the problem. Well, 102 00:05:24,480 --> 00:05:27,119 Speaker 4: let's either the plugs, coil or injector according to the 103 00:05:27,200 --> 00:05:31,040 Speaker 4: simple interpretation. So I went, well, the plugs have about 104 00:05:31,160 --> 00:05:35,640 Speaker 4: old fifteen, maybe twenty thousand miles on them, and I 105 00:05:35,680 --> 00:05:38,000 Speaker 4: didn't want to get into injectors. I went ahead and 106 00:05:38,080 --> 00:05:42,880 Speaker 4: replaced number two coal, and sure enough, the next day 107 00:05:42,960 --> 00:05:46,800 Speaker 4: or two got a missfire on number two. Well, okay, 108 00:05:46,880 --> 00:05:49,880 Speaker 4: let's go ahead and get in there. And I've swapped 109 00:05:50,600 --> 00:05:55,599 Speaker 4: one in two plugs and put the new coil on 110 00:05:55,760 --> 00:05:59,960 Speaker 4: number one, and all of a sudden, get a code, 111 00:06:00,400 --> 00:06:04,800 Speaker 4: Well guess what's missfire and on number one. So I figured, okay, 112 00:06:05,279 --> 00:06:07,880 Speaker 4: must be plugged. So I went and bought new plugs, 113 00:06:08,480 --> 00:06:12,839 Speaker 4: put those in and got about uh oh, let's see. 114 00:06:12,839 --> 00:06:14,479 Speaker 4: While I was in there, I went ahead and bit 115 00:06:14,520 --> 00:06:18,920 Speaker 4: the bullet and cleaned the injectors, and so got about 116 00:06:18,920 --> 00:06:22,200 Speaker 4: two hundred miles. And all of a sudden, check engine 117 00:06:22,279 --> 00:06:25,800 Speaker 4: light traction comes on and it says I'm getting intermitt 118 00:06:25,839 --> 00:06:30,200 Speaker 4: and misfires on all cylinders, particularly number one. I'm at 119 00:06:30,240 --> 00:06:30,719 Speaker 4: a loss. 120 00:06:30,839 --> 00:06:34,560 Speaker 2: Okay, help me wrong. So where'd we get the coil from? 121 00:06:35,320 --> 00:06:36,520 Speaker 4: Got it from Toyota? 122 00:06:36,760 --> 00:06:38,440 Speaker 2: Okay, So it's a real Toyota coil. 123 00:06:38,760 --> 00:06:40,800 Speaker 4: It is a Toyota cold, all right. 124 00:06:40,680 --> 00:06:42,760 Speaker 2: When the misfires occur, do you have a scam tool 125 00:06:42,760 --> 00:06:44,599 Speaker 2: that we'll read misfires. 126 00:06:45,920 --> 00:06:47,839 Speaker 4: After the fact, not during driving. 127 00:06:48,640 --> 00:06:50,600 Speaker 2: Okay, it's gonna make it a little bit more difficult, 128 00:06:50,600 --> 00:06:53,200 Speaker 2: because I'd love to see. I would love to see. 129 00:06:53,920 --> 00:06:56,200 Speaker 2: Do I have a fuel trim problem? 130 00:06:57,000 --> 00:06:57,240 Speaker 3: You ever? 131 00:06:57,360 --> 00:06:58,640 Speaker 2: You ever mold the lawn George? 132 00:06:59,480 --> 00:07:00,320 Speaker 3: Yes, sir, you ever? 133 00:07:00,480 --> 00:07:04,520 Speaker 2: You know the lawnmower doesn't run right? Why? Why does 134 00:07:04,560 --> 00:07:08,520 Speaker 2: the lawnmower not run right? Bad? Plug right? 135 00:07:09,640 --> 00:07:10,960 Speaker 4: Usually a plug. 136 00:07:10,960 --> 00:07:17,800 Speaker 2: Right, carburetor problem, or something mechanical in the engine right, 137 00:07:17,840 --> 00:07:22,120 Speaker 2: burnt valve, usually in the head well. And you know, 138 00:07:22,200 --> 00:07:25,400 Speaker 2: here's a case where and and for the record, if 139 00:07:25,440 --> 00:07:28,240 Speaker 2: we were down to where it was occurring on one cylinder, 140 00:07:29,080 --> 00:07:31,000 Speaker 2: I would have loved to have just taken the coil 141 00:07:31,080 --> 00:07:33,000 Speaker 2: and put it on one cylinder, and the plug and 142 00:07:33,040 --> 00:07:36,480 Speaker 2: put it on another cylinder. Which way did the misfire go? What? 143 00:07:36,480 --> 00:07:37,200 Speaker 2: What followed? 144 00:07:37,240 --> 00:07:37,320 Speaker 5: What? 145 00:07:38,320 --> 00:07:41,880 Speaker 2: M all right? What you've done now is and and 146 00:07:42,000 --> 00:07:44,240 Speaker 2: I get it. I'm not scolding. I'm just saying, what 147 00:07:44,280 --> 00:07:47,680 Speaker 2: you've done now is you've you've changed the parameters of everything. 148 00:07:47,680 --> 00:07:49,800 Speaker 2: So we have to we have to think and start over, 149 00:07:50,360 --> 00:07:54,760 Speaker 2: all right, So if we've got a misfire being reported 150 00:07:54,800 --> 00:07:59,080 Speaker 2: on all cylinders, I'd sure love to see that live 151 00:07:59,120 --> 00:08:03,040 Speaker 2: on a scan tool. Yeah, what's what's what's actually going on? 152 00:08:03,120 --> 00:08:07,640 Speaker 2: Which cylinder has the worst misfire going on? A misfire 153 00:08:07,720 --> 00:08:10,160 Speaker 2: on two cylinders, for an example, can affect the engine 154 00:08:10,320 --> 00:08:14,360 Speaker 2: in the way that it operates and create what we'll 155 00:08:14,360 --> 00:08:17,680 Speaker 2: call ghost misfires. They're not really misfiring, but it's affecting 156 00:08:17,720 --> 00:08:21,240 Speaker 2: crank speed and causing it to stutter in that hole. 157 00:08:21,320 --> 00:08:23,720 Speaker 2: You ever think about how a computer determines whether there's 158 00:08:23,720 --> 00:08:24,920 Speaker 2: a misfire going on or not? 159 00:08:25,920 --> 00:08:28,040 Speaker 4: No, all right, so baffles me. 160 00:08:28,920 --> 00:08:34,280 Speaker 2: So you got a kitchen table in your house. Of course, 161 00:08:34,400 --> 00:08:36,559 Speaker 2: the doorbell rings, Get up and walk from the kitchen 162 00:08:36,600 --> 00:08:40,400 Speaker 2: table to the door at at at whatever pace you choose. Right, 163 00:08:41,040 --> 00:08:44,320 Speaker 2: that's your that's your pace, that's your that's your that's 164 00:08:44,400 --> 00:08:46,480 Speaker 2: that's the length of time it takes you. Let's say 165 00:08:46,480 --> 00:08:49,640 Speaker 2: it takes you eight seconds, all right, all right, But 166 00:08:49,800 --> 00:08:51,960 Speaker 2: now you come home from work one day and you 167 00:08:52,080 --> 00:08:54,160 Speaker 2: drop something on your foot and you're walking with a limp. 168 00:08:54,240 --> 00:08:58,000 Speaker 2: You can't do it in eight seconds, right, So, so 169 00:08:58,120 --> 00:08:59,560 Speaker 2: the length of time it takes you to get to 170 00:08:59,559 --> 00:09:02,480 Speaker 2: the front door to answer the doorbell. It changes. The 171 00:09:02,600 --> 00:09:09,040 Speaker 2: duration of time changes. Right. A crank shaft rotates at 172 00:09:09,160 --> 00:09:13,000 Speaker 2: set speed. The computer knows when it fires number one. 173 00:09:13,640 --> 00:09:15,840 Speaker 2: It's programming tells it it's going to take it so 174 00:09:15,920 --> 00:09:18,560 Speaker 2: many milliseconds if you want to say seconds to ease 175 00:09:18,600 --> 00:09:21,720 Speaker 2: the conversation and not make math an issue. It's going 176 00:09:21,760 --> 00:09:24,439 Speaker 2: to take so many seconds to rotate from the first 177 00:09:24,480 --> 00:09:26,960 Speaker 2: firing event to the next firing event, to the next 178 00:09:27,000 --> 00:09:31,000 Speaker 2: firing event and so on. And it knows that speed 179 00:09:31,559 --> 00:09:35,959 Speaker 2: based on engine RPM, load, etc. Well, if all of 180 00:09:36,040 --> 00:09:38,560 Speaker 2: a sudden it's coming around and getting ready to fire, 181 00:09:38,720 --> 00:09:41,000 Speaker 2: just fired number one, and it's getting ready to fire 182 00:09:41,120 --> 00:09:44,840 Speaker 2: number number four, all right, and it's supposed to take 183 00:09:44,920 --> 00:09:49,680 Speaker 2: eight seconds, and now it takes ten. WHOA what happened? 184 00:09:50,200 --> 00:09:54,600 Speaker 2: George misstepped? Okay, so it says, hey, there's a misfire 185 00:09:54,679 --> 00:09:59,920 Speaker 2: going on here. Depending upon the severity and how how 186 00:10:00,000 --> 00:10:05,560 Speaker 2: how consistently that happens, it can become a P zero 187 00:10:05,679 --> 00:10:08,960 Speaker 2: three hundred, which is random missfire because they can't tell 188 00:10:09,040 --> 00:10:12,840 Speaker 2: which cylinder is actually missing, or it's going to become 189 00:10:12,840 --> 00:10:16,320 Speaker 2: an identifying missfire. Three oh one, three oh two, three 190 00:10:16,360 --> 00:10:17,440 Speaker 2: oh three, and so on. 191 00:10:18,280 --> 00:10:20,040 Speaker 4: That's what That's what I had last time was a 192 00:10:20,080 --> 00:10:23,120 Speaker 4: P three to zero P three hundred and then uh 193 00:10:23,720 --> 00:10:25,400 Speaker 4: and P three zero one. 194 00:10:25,520 --> 00:10:29,040 Speaker 2: Right now, one of the things I want to see 195 00:10:29,480 --> 00:10:32,520 Speaker 2: while I'm looking at a misfire like this. You ever 196 00:10:32,559 --> 00:10:35,680 Speaker 2: worked on a car in in the older days when 197 00:10:35,720 --> 00:10:38,079 Speaker 2: it was carbureted and it ran roughedt island. You put 198 00:10:38,080 --> 00:10:40,520 Speaker 2: a rag over the top of the carburetor. It smoothed out. 199 00:10:41,320 --> 00:10:43,439 Speaker 4: Oh yeah, I got my Studi Baker back here, I'm 200 00:10:43,440 --> 00:10:44,280 Speaker 4: working on it, right. 201 00:10:45,200 --> 00:10:51,240 Speaker 2: You ever think about why that happened? You changed the 202 00:10:51,280 --> 00:10:54,840 Speaker 2: fuel mixture, right, it was It was usually dirt and 203 00:10:54,960 --> 00:10:58,160 Speaker 2: air bleed or something was restricted and you altered the 204 00:10:58,160 --> 00:11:02,320 Speaker 2: fuel curve. So I want to know, on a modern car, 205 00:11:02,520 --> 00:11:04,920 Speaker 2: where's my fuel trim? At idol? Where's my fuel trim 206 00:11:05,000 --> 00:11:07,760 Speaker 2: and cruise? When this, when it's misfiring, what's it doing? 207 00:11:08,720 --> 00:11:11,000 Speaker 2: In some cases, you know, you can tell take a 208 00:11:11,000 --> 00:11:14,960 Speaker 2: scan tool, look at data and see, I've got misfires 209 00:11:14,960 --> 00:11:18,520 Speaker 2: at idol, but they go away off idle. Well, misfires 210 00:11:18,800 --> 00:11:23,760 Speaker 2: that go away off idle are generally associated more with 211 00:11:23,960 --> 00:11:28,280 Speaker 2: either a fuel trim issue or possibly a valve train issue. 212 00:11:29,120 --> 00:11:31,440 Speaker 4: A good good point. In fact, once I get up 213 00:11:31,440 --> 00:11:34,520 Speaker 4: to speed, I mean it runs pretty smooth, but it 214 00:11:34,559 --> 00:11:36,560 Speaker 4: does have a rough IDOL and low end. 215 00:11:36,800 --> 00:11:40,280 Speaker 2: Right, you know, maybe we've got an EGR valve stuck open? 216 00:11:40,320 --> 00:11:42,400 Speaker 2: What years? This is an O nine. I believe we've 217 00:11:42,400 --> 00:11:46,400 Speaker 2: got an EGR on this car. If we've got an EGR, 218 00:11:46,480 --> 00:11:50,680 Speaker 2: do we have a stuck open EGR valve? So I 219 00:11:50,760 --> 00:11:53,720 Speaker 2: think what I want you to do. I'm gonna ask 220 00:11:53,760 --> 00:11:55,720 Speaker 2: you to spend a couple of bucks and go buy 221 00:11:55,720 --> 00:11:58,600 Speaker 2: a scan tool that shows live data. Because, brother, you're 222 00:11:58,640 --> 00:12:01,880 Speaker 2: more than mechanically qualify. You got to. I can already 223 00:12:01,880 --> 00:12:04,480 Speaker 2: tell you've got enough smarts between your ears. You're working 224 00:12:04,520 --> 00:12:08,520 Speaker 2: on older studebakers. You're mechanically inclined. Obviously, that's why you're 225 00:12:08,559 --> 00:12:11,640 Speaker 2: here listening to this show. And I think it's time 226 00:12:11,679 --> 00:12:14,120 Speaker 2: for you to get a scan tool that just will 227 00:12:14,160 --> 00:12:15,440 Speaker 2: show you a few things. 228 00:12:15,880 --> 00:12:17,840 Speaker 4: Yeah, my son, my son in law that turned me 229 00:12:17,880 --> 00:12:20,040 Speaker 4: on to you, gave me a nice scan tool and 230 00:12:20,440 --> 00:12:23,040 Speaker 4: he's talking about, oh, we'll get together and ride and 231 00:12:23,120 --> 00:12:25,800 Speaker 4: analyze it. And also, right, it has a capability. I 232 00:12:25,880 --> 00:12:26,840 Speaker 4: just don't know how to use it. 233 00:12:26,920 --> 00:12:28,920 Speaker 2: Yeah, well, I think that's that's where you are, kiddo. 234 00:12:29,440 --> 00:12:32,400 Speaker 2: All right, so do that, get some scan tool analysis. 235 00:12:32,440 --> 00:12:34,240 Speaker 2: If you have any other questions, you want me ron 236 00:12:34,280 --> 00:12:37,240 Speaker 2: at cardoctorshow dot com, send me some print out, send 237 00:12:37,280 --> 00:12:39,280 Speaker 2: me some data, and I'll be glad to coach you 238 00:12:39,320 --> 00:12:40,559 Speaker 2: a long all right, and then you give us a 239 00:12:40,600 --> 00:12:42,199 Speaker 2: call back. You let us know what happened up here 240 00:12:42,240 --> 00:12:42,560 Speaker 2: on air. 241 00:12:42,600 --> 00:12:44,960 Speaker 4: All right, kiddo, you'll hear from me again. 242 00:12:45,000 --> 00:12:47,600 Speaker 2: All right, You're very welcome, George anytime. All right, I'm 243 00:12:47,679 --> 00:12:49,360 Speaker 2: running any in the car, doctor, let me run. I'll 244 00:12:49,360 --> 00:13:05,280 Speaker 2: be back right after this. Hey, let's get out and 245 00:13:05,320 --> 00:13:09,240 Speaker 2: talk to Jeff in Pennsylvania fourteen Chevy Sonic do you Sonic? Sorry, 246 00:13:09,240 --> 00:13:13,960 Speaker 2: I couldn't resist the Sorry Jeff, what's going on? 247 00:13:14,040 --> 00:13:14,240 Speaker 5: Back? 248 00:13:14,280 --> 00:13:14,559 Speaker 2: Okay? 249 00:13:15,360 --> 00:13:18,560 Speaker 5: Well, sometimes, well I should say sometimes most of the times. 250 00:13:18,559 --> 00:13:20,880 Speaker 5: When I'm going down the road, the car runs great, 251 00:13:21,520 --> 00:13:24,200 Speaker 5: and it has a turbo and that works really well. 252 00:13:24,280 --> 00:13:26,959 Speaker 5: In fact, I think it helps decrease my gas knowledge. 253 00:13:27,000 --> 00:13:30,120 Speaker 5: But anyways, when I come to a stop, the car 254 00:13:30,160 --> 00:13:35,360 Speaker 5: will sometimes just start jumping, like bouncing around, and sometimes 255 00:13:35,360 --> 00:13:40,600 Speaker 5: I put a neutral goes away. Then sometimes it doesn't, so. 256 00:13:40,640 --> 00:13:44,160 Speaker 2: That bounces around like a rough idol or like you're 257 00:13:44,200 --> 00:13:45,160 Speaker 2: feeling vibration. 258 00:13:46,120 --> 00:13:47,839 Speaker 3: Well, I'm feeling like the tires are going to come 259 00:13:47,840 --> 00:13:51,120 Speaker 3: off the ground. 260 00:13:52,040 --> 00:13:53,360 Speaker 2: What do you what do you mean like the tires 261 00:13:53,400 --> 00:13:54,960 Speaker 2: are gonna come off the ground, like the engine starts 262 00:13:55,000 --> 00:13:55,680 Speaker 2: running badly. 263 00:13:57,240 --> 00:14:00,400 Speaker 3: No, it's just the car literally like it. It feels 264 00:14:00,400 --> 00:14:04,840 Speaker 3: like it's bouncing, it's shaking, sitting the engine. It's it's 265 00:14:04,880 --> 00:14:07,199 Speaker 3: sort of you know, coughing and sputtering, you know what 266 00:14:07,240 --> 00:14:08,960 Speaker 3: I mean. Sometimes I have to well I put it 267 00:14:08,960 --> 00:14:11,280 Speaker 3: in neutral, I have to try to rev it up 268 00:14:11,600 --> 00:14:13,719 Speaker 3: to get it going again, or put it in park. 269 00:14:14,040 --> 00:14:16,840 Speaker 2: So so it'll move it out. It almost feels like 270 00:14:16,920 --> 00:14:20,200 Speaker 2: it's like it's flooding out, like it's running real rich 271 00:14:20,280 --> 00:14:26,640 Speaker 2: for a moment. Yeah, okay, how many miles a right? 272 00:14:26,960 --> 00:14:28,280 Speaker 2: How many miles are on this. 273 00:14:28,720 --> 00:14:31,480 Speaker 3: There's two hundred and fifteen thousand miles. I'm getting ready 274 00:14:31,480 --> 00:14:33,000 Speaker 3: to take it to the mechanic to work on. I 275 00:14:33,080 --> 00:14:34,440 Speaker 3: just wanted to see if you could give me a 276 00:14:34,520 --> 00:14:38,280 Speaker 3: heads up on maybe a potential problem or solution. So 277 00:14:38,760 --> 00:14:40,720 Speaker 3: I'm going with a new mechanic, so I don't know 278 00:14:40,760 --> 00:14:41,760 Speaker 3: a lot about him yet. 279 00:14:41,680 --> 00:14:45,520 Speaker 2: Right, Yeah, well, listen, I'm hoping that the mechanic, you know, 280 00:14:45,560 --> 00:14:47,320 Speaker 2: he's going to say two things to you. Number one, 281 00:14:47,320 --> 00:14:49,080 Speaker 2: can we go for a ride so I can experience 282 00:14:49,120 --> 00:14:52,080 Speaker 2: it right? And number two that he's going to do 283 00:14:52,120 --> 00:14:54,000 Speaker 2: a complete scan on the car, whether it's got a 284 00:14:54,080 --> 00:14:55,680 Speaker 2: check engine light on or not. Does it have any 285 00:14:55,760 --> 00:14:56,840 Speaker 2: lights on on the dashboard. 286 00:14:57,560 --> 00:14:59,680 Speaker 3: It does have a check engine light on. It's been 287 00:14:59,680 --> 00:15:02,160 Speaker 3: on for for a while, and like I said, it's 288 00:15:02,160 --> 00:15:04,760 Speaker 3: been running pretty good other than this problem. And I 289 00:15:04,880 --> 00:15:06,440 Speaker 3: just I was gonna get rid of the car, and 290 00:15:06,480 --> 00:15:08,720 Speaker 3: I decided to keep it as a as a beater car. 291 00:15:08,800 --> 00:15:10,920 Speaker 2: Basically, what do you know what the code is that 292 00:15:11,000 --> 00:15:11,480 Speaker 2: it's got. 293 00:15:12,000 --> 00:15:13,800 Speaker 3: No I have no idea what I had the codes? 294 00:15:14,000 --> 00:15:17,040 Speaker 2: Okay, so obviously that's gonna you know, that's gonna be 295 00:15:17,040 --> 00:15:19,160 Speaker 2: the first step. But here's the catch. How long has 296 00:15:19,160 --> 00:15:23,680 Speaker 2: the light been on for quite a while? Six months? 297 00:15:23,680 --> 00:15:24,040 Speaker 4: A year? 298 00:15:24,360 --> 00:15:24,960 Speaker 2: Two years? 299 00:15:25,120 --> 00:15:25,360 Speaker 3: Yeah? 300 00:15:25,800 --> 00:15:26,480 Speaker 4: Which years? 301 00:15:26,520 --> 00:15:31,840 Speaker 2: Two years? So you ever get hurt in your lifetime 302 00:15:31,880 --> 00:15:32,840 Speaker 2: and you kind of walked. 303 00:15:32,600 --> 00:15:36,840 Speaker 3: With a limp, I still do, yeah, right, And you. 304 00:15:36,800 --> 00:15:41,080 Speaker 2: Notice how your body sort of adjusted for it, right, 305 00:15:41,320 --> 00:15:43,720 Speaker 2: And even in some cases you got hurt and the 306 00:15:44,040 --> 00:15:46,400 Speaker 2: injury corrected itself. But you had to you had to 307 00:15:46,440 --> 00:15:51,600 Speaker 2: train yourself to walk correctly again, right, and it stopped me. 308 00:15:51,880 --> 00:15:54,440 Speaker 2: It stopped, it stopped testing the rest of it. My 309 00:15:54,520 --> 00:15:59,760 Speaker 2: point becomes, cars today are smart. Right, So if it's 310 00:16:00,640 --> 00:16:02,920 Speaker 2: I don't know, pick a number, ten, twelve, eighteen, how 311 00:16:02,960 --> 00:16:08,320 Speaker 2: many sensors you think your car has, Let's say eighteen, right, yeah, 312 00:16:08,440 --> 00:16:12,000 Speaker 2: So if there's eighteen sensors, it's testing every sensor of 313 00:16:12,040 --> 00:16:14,760 Speaker 2: every moment of every second of operation. But all of 314 00:16:14,800 --> 00:16:18,240 Speaker 2: a sudden one of them is a problem. Those automobile 315 00:16:18,280 --> 00:16:21,400 Speaker 2: engineers are pretty smart, you know, Jeff. They're gonna say, well, 316 00:16:21,440 --> 00:16:23,560 Speaker 2: instead of getting Jeff stuck on the side of the road, 317 00:16:24,200 --> 00:16:26,720 Speaker 2: we're gonna allow this car to learn. So when censor 318 00:16:26,800 --> 00:16:30,040 Speaker 2: A was at this, we know that censor B was 319 00:16:30,080 --> 00:16:32,440 Speaker 2: doing that, and censor C was this, So therefore we 320 00:16:32,480 --> 00:16:35,200 Speaker 2: can use calculated values. We don't need to run those 321 00:16:35,240 --> 00:16:39,840 Speaker 2: self tests anymore. And here's my point, the fact that 322 00:16:39,880 --> 00:16:42,920 Speaker 2: the check engine light's been on for two years, you're 323 00:16:42,960 --> 00:16:47,320 Speaker 2: gonna have to fix problem A, clear the code, and 324 00:16:47,400 --> 00:16:53,920 Speaker 2: let the vehicle run its self testing monitors, right, yeah, 325 00:16:54,040 --> 00:16:57,680 Speaker 2: and then see what if anything comes next. Because what 326 00:16:57,720 --> 00:16:59,640 Speaker 2: I'm trying to say is at two hundred and fifteen 327 00:16:59,640 --> 00:17:06,600 Speaker 2: thousand miles, what's next? What test didn't did run in 328 00:17:06,600 --> 00:17:11,399 Speaker 2: the last two years? So what's the accumulative damage that 329 00:17:11,440 --> 00:17:14,080 Speaker 2: this could possibly have over a twenty four month period? 330 00:17:15,040 --> 00:17:18,320 Speaker 2: And that's so even though the check engine light's been great, 331 00:17:19,320 --> 00:17:21,320 Speaker 2: arm check engine light's been on, and the vehicle's been 332 00:17:21,359 --> 00:17:25,480 Speaker 2: running great, there's still tests. I guarantee you it hasn't run. 333 00:17:25,640 --> 00:17:28,200 Speaker 2: Let me make it simple. Let's say it's a bad 334 00:17:28,240 --> 00:17:32,240 Speaker 2: thermostat P zero one twenty eight, right, and I don't 335 00:17:32,240 --> 00:17:34,320 Speaker 2: know what it is, but let's just say that the 336 00:17:34,320 --> 00:17:37,879 Speaker 2: thermostat was allowing the engine to run eight degrees colder 337 00:17:37,920 --> 00:17:41,040 Speaker 2: than speck, so instead of running two hundred degrees, it 338 00:17:41,119 --> 00:17:44,840 Speaker 2: ran one hundred and ninety two. That difference is enough 339 00:17:44,880 --> 00:17:47,000 Speaker 2: to cause the computer to go into lockout where it 340 00:17:47,040 --> 00:17:51,719 Speaker 2: won't run self tests. And now there's we'll tell you what. 341 00:17:51,840 --> 00:17:53,800 Speaker 2: Sit tight. Let me pull over, take this pause. When 342 00:17:53,800 --> 00:17:55,480 Speaker 2: we come back, we'll pick it up from here. I'm 343 00:17:55,520 --> 00:17:57,200 Speaker 2: running any in the car. Doctor.

Then I got to get 354 00:18:49,280 --> 00:18:49,640 Speaker 2: the Lee. 355 00:18:49,560 --> 00:18:54,200 Speaker 3: And Georgia, just because there's something else that might be 356 00:18:54,240 --> 00:18:57,480 Speaker 3: affecting this also. Okay, when I go and fill up 357 00:18:57,520 --> 00:18:59,720 Speaker 3: with gas and then I go and start the car, 358 00:19:00,280 --> 00:19:03,000 Speaker 3: it just wants to sputter and not run smooth. So 359 00:19:03,080 --> 00:19:04,680 Speaker 3: I have to sit there and rev it up, ton't 360 00:19:04,720 --> 00:19:06,440 Speaker 3: run smooth, and I'm good to take off. 361 00:19:06,680 --> 00:19:10,080 Speaker 2: Okay, So you might have a bad purge valve Okay, 362 00:19:10,480 --> 00:19:17,639 Speaker 2: which which you know? Again? What's the fault code? Have 363 00:19:17,760 --> 00:19:19,040 Speaker 2: you ever had the code scanned? 364 00:19:20,160 --> 00:19:20,200 Speaker 4: No? 365 00:19:20,720 --> 00:19:21,800 Speaker 2: Can I ask you why. 366 00:19:21,600 --> 00:19:23,320 Speaker 3: I'm having an issue with the radio? 367 00:19:23,840 --> 00:19:27,760 Speaker 2: Say hawk back up? Can I ask why? And the 368 00:19:27,800 --> 00:19:30,400 Speaker 2: reason I'm asking is not that is not to highlight 369 00:19:30,480 --> 00:19:32,960 Speaker 2: you or pick on you. I'm just trying to demonstrate 370 00:19:33,000 --> 00:19:35,520 Speaker 2: the value. You know, if it was your leg that 371 00:19:35,600 --> 00:19:37,080 Speaker 2: was hurting, why did you at least go to the 372 00:19:37,080 --> 00:19:39,200 Speaker 2: dock and get it checked out? I would hope. 373 00:19:40,840 --> 00:19:43,919 Speaker 3: Right, Well, I did have it checked out, and the 374 00:19:43,960 --> 00:19:45,840 Speaker 3: person who checked it out said, oh, there's lots of 375 00:19:45,880 --> 00:19:47,480 Speaker 3: problems and it's going to cost you a lot to 376 00:19:47,520 --> 00:19:50,359 Speaker 3: fix it. And then I wasn't driving the car for 377 00:19:50,400 --> 00:19:52,080 Speaker 3: a while. I mean I was running it, but I 378 00:19:52,119 --> 00:19:56,199 Speaker 3: wasn't driving it. And so that's why it's the situation now. 379 00:19:56,200 --> 00:19:58,159 Speaker 3: I'd like to drive it again and maybe have it 380 00:19:58,200 --> 00:20:00,960 Speaker 3: as a beater, and if it's too expensive, I'm just gonna. 381 00:20:00,680 --> 00:20:03,359 Speaker 2: Get rid of it right well. And like I said before, 382 00:20:03,480 --> 00:20:05,320 Speaker 2: I can't tell you if it's going to be expensive 383 00:20:05,400 --> 00:20:07,439 Speaker 2: or not because two years with a check engine light on, 384 00:20:08,400 --> 00:20:10,800 Speaker 2: I can't tell you if it's one problem, three problems, 385 00:20:10,840 --> 00:20:11,600 Speaker 2: five problems. 386 00:20:11,880 --> 00:20:13,920 Speaker 3: Yeah, I understand my faults. 387 00:20:14,080 --> 00:20:17,200 Speaker 2: Yeah, yeah, no, And again not to listen. My job 388 00:20:17,240 --> 00:20:20,359 Speaker 2: is to educate you guys. But that's the you know, 389 00:20:20,480 --> 00:20:23,080 Speaker 2: and and you know, but that's that's the reality of it. 390 00:20:23,119 --> 00:20:24,600 Speaker 2: For lack of a better way. You had to comment 391 00:20:24,640 --> 00:20:24,960 Speaker 2: about the. 392 00:20:25,000 --> 00:20:27,040 Speaker 5: Radio, Yeah, I want to. 393 00:20:27,119 --> 00:20:29,480 Speaker 3: I just noticed this. It's like when you're going down 394 00:20:29,520 --> 00:20:32,080 Speaker 3: the road, it'll jump to another station. They'll like beep, 395 00:20:32,160 --> 00:20:34,520 Speaker 3: make a noise and jump to another station. Or if 396 00:20:34,520 --> 00:20:36,680 Speaker 3: you try to get back to it, it might lock up, 397 00:20:37,240 --> 00:20:40,160 Speaker 3: or it might change different screens on on the screen. 398 00:20:41,160 --> 00:20:44,320 Speaker 2: That sounds like from my seat here, if I've got 399 00:20:44,320 --> 00:20:47,600 Speaker 2: constant power and ground going to the radio, which is 400 00:20:47,600 --> 00:20:51,159 Speaker 2: what I would monitor on a road test, then it 401 00:20:51,240 --> 00:20:53,720 Speaker 2: sounds like I've probably got an internal radio fault and 402 00:20:53,760 --> 00:20:55,960 Speaker 2: I'm gonna send it out to a repair center to 403 00:20:56,040 --> 00:20:59,000 Speaker 2: have it looked at. All right, but you know, before 404 00:20:59,040 --> 00:21:01,360 Speaker 2: you go that routelet's get let's get it running right 405 00:21:02,160 --> 00:21:05,520 Speaker 2: and and for the record, before you before we go along, well, 406 00:21:05,560 --> 00:21:07,679 Speaker 2: let me just I'll put an after market radio in it. 407 00:21:08,560 --> 00:21:10,520 Speaker 2: I would want to look at the wiring and how 408 00:21:10,760 --> 00:21:12,880 Speaker 2: is that radio part of the can or the controlled 409 00:21:12,920 --> 00:21:16,760 Speaker 2: area network system? And is putting an aftermarket radio when 410 00:21:16,760 --> 00:21:19,840 Speaker 2: it's going to affect operation and communication somewhere else down 411 00:21:19,840 --> 00:21:23,840 Speaker 2: the line. So there's things to consider. But let's get 412 00:21:23,840 --> 00:21:27,120 Speaker 2: the check engine light resolved first, all right, kiddo. Okay, 413 00:21:27,200 --> 00:21:31,080 Speaker 2: so you're very welcome, sir. Happy to have you, Lee Georgia. 414 00:21:31,160 --> 00:21:32,280 Speaker 2: How can I help you today, sir? 415 00:21:34,560 --> 00:21:39,080 Speaker 6: Yes, sir, I've got a twenty eleven Shay Traverse. I'm 416 00:21:39,119 --> 00:21:43,359 Speaker 6: having cranking issues. I've done did everything on your video 417 00:21:43,560 --> 00:21:45,040 Speaker 6: that you had posted a while back. 418 00:21:45,160 --> 00:21:47,040 Speaker 2: We talked about this car. You and I didn't we 419 00:21:47,119 --> 00:21:52,280 Speaker 2: did we? Did we facebook or something? Or we we? Okay, 420 00:21:52,400 --> 00:21:55,160 Speaker 2: So so refresh refresh my memory because I remember then, 421 00:21:55,280 --> 00:21:58,000 Speaker 2: remember the specifics. You went through the purple wire going 422 00:21:58,000 --> 00:22:00,200 Speaker 2: down to the starter. You don't have twelve vaults there. 423 00:22:01,080 --> 00:22:02,679 Speaker 2: You went to the relay in the jump in the 424 00:22:02,760 --> 00:22:05,480 Speaker 2: in the underhood fuse block. Do you have do you 425 00:22:05,480 --> 00:22:07,840 Speaker 2: have hot at thirty? Do you have ground signal from 426 00:22:07,840 --> 00:22:09,119 Speaker 2: the PCM on eighty six? 427 00:22:11,760 --> 00:22:13,800 Speaker 6: It's been a while since I've missed with this thing. 428 00:22:15,200 --> 00:22:17,800 Speaker 6: I do know that I sent and got a new 429 00:22:17,960 --> 00:22:21,119 Speaker 6: e CM put in, all right, ordered one, got it 430 00:22:21,160 --> 00:22:25,200 Speaker 6: put in, and I'm still able to run power jump 431 00:22:25,240 --> 00:22:29,680 Speaker 6: power from the hot terminal on the fuse block to 432 00:22:29,840 --> 00:22:32,879 Speaker 6: the yellow wire coming down the fuse block, going to 433 00:22:32,960 --> 00:22:38,040 Speaker 6: the e CM and it cranks, but no start. But 434 00:22:38,160 --> 00:22:41,280 Speaker 6: inside it does not crank, start, don't do anything. 435 00:22:41,400 --> 00:22:44,960 Speaker 2: So I'm looking for okay. So the reason that works 436 00:22:45,000 --> 00:22:47,640 Speaker 2: is because the PCM is applying power on that yellow 437 00:22:48,320 --> 00:22:51,320 Speaker 2: and it's constantly grounded at one ten. So what you've 438 00:22:51,320 --> 00:22:53,440 Speaker 2: done is you've proved the ground one ten, which is 439 00:22:53,480 --> 00:22:55,640 Speaker 2: in the back rear corner of the cylinder head is good. 440 00:22:56,280 --> 00:23:01,760 Speaker 2: All right, So so that being said, all right, why 441 00:23:01,760 --> 00:23:03,960 Speaker 2: aren't we getting a signal out of the PCM. Let's 442 00:23:04,000 --> 00:23:07,679 Speaker 2: back up a second, refresh my memory. What sort of 443 00:23:07,840 --> 00:23:10,320 Speaker 2: code retrieval? What sort of scan tool work? If you've 444 00:23:10,320 --> 00:23:11,159 Speaker 2: done with this car? 445 00:23:12,359 --> 00:23:15,280 Speaker 6: We scanned it a while back. It comes from it's 446 00:23:15,320 --> 00:23:19,040 Speaker 6: been three other shops right, come here, And when she 447 00:23:19,119 --> 00:23:22,080 Speaker 6: brought it here, she said the motor was knocking already 448 00:23:22,119 --> 00:23:24,960 Speaker 6: had a warranty motor, but also said it wouldn't crank 449 00:23:25,040 --> 00:23:28,399 Speaker 6: back up for the other shop. So we tried to 450 00:23:28,400 --> 00:23:30,040 Speaker 6: get it to crank so I could hear the knock, 451 00:23:30,920 --> 00:23:34,719 Speaker 6: and we weren't getting anything, no signal for nothing. Okay, 452 00:23:34,760 --> 00:23:37,119 Speaker 6: So most like it's like the like the pat system 453 00:23:37,200 --> 00:23:37,719 Speaker 6: was messed up. 454 00:23:37,800 --> 00:23:38,160 Speaker 3: All right. 455 00:23:38,280 --> 00:23:43,920 Speaker 2: So so if you're going in you're making model, right, yeah? 456 00:23:44,000 --> 00:23:44,200 Speaker 4: Yeah? 457 00:23:44,200 --> 00:23:45,680 Speaker 2: What and what scan tool were you using? 458 00:23:46,000 --> 00:23:48,399 Speaker 6: Was it a I got a trite and BT and 459 00:23:48,440 --> 00:23:48,840 Speaker 6: snap on? 460 00:23:49,040 --> 00:23:51,560 Speaker 2: Okay? Right, so you did it. So if you do 461 00:23:51,640 --> 00:23:54,600 Speaker 2: a if you do a complete system scan, what FOLT 462 00:23:54,600 --> 00:23:55,719 Speaker 2: codes do you get anything? 463 00:23:56,800 --> 00:23:57,960 Speaker 6: It doesn't give me anything? 464 00:23:58,000 --> 00:24:01,600 Speaker 2: Now, all right? So does it communicate with all modules? 465 00:24:02,240 --> 00:24:02,320 Speaker 4: No? 466 00:24:03,160 --> 00:24:07,000 Speaker 2: It doesn't, it doesn't. So so do we have a 467 00:24:07,040 --> 00:24:12,600 Speaker 2: network communication? Full? Right? So if we go down to 468 00:24:12,680 --> 00:24:14,159 Speaker 2: the if we go down to the A L d 469 00:24:14,359 --> 00:24:18,080 Speaker 2: L connector, right, if we go down to the you know, 470 00:24:18,200 --> 00:24:21,160 Speaker 2: under the under the dash, if we go across pen 471 00:24:21,359 --> 00:24:25,560 Speaker 2: six and fourteen, what's the resistance? I have not checked 472 00:24:25,560 --> 00:24:28,359 Speaker 2: that sixty oms? Got to see sixty oms? Do we 473 00:24:28,400 --> 00:24:31,560 Speaker 2: have an open on the CANbus? But see, I'm surprised 474 00:24:31,600 --> 00:24:35,400 Speaker 2: if you've got if you've got no communication, all right, 475 00:24:35,440 --> 00:24:37,000 Speaker 2: do you have a let me back up a second, 476 00:24:37,080 --> 00:24:45,000 Speaker 2: do you have a OBD two breakup box? You know what? 477 00:24:45,440 --> 00:24:47,600 Speaker 2: They're cheap. You'll you'll really love it. Rather than trying 478 00:24:47,600 --> 00:24:49,719 Speaker 2: to get under the dash and measure voltage and ground 479 00:24:50,000 --> 00:24:54,480 Speaker 2: at the ald L connector, you can actually it's it'll 480 00:24:54,480 --> 00:24:58,880 Speaker 2: actually go between the connector and your scan tool and 481 00:24:59,080 --> 00:25:01,520 Speaker 2: you can sit there with a voltmeter and monitor voltage 482 00:25:01,560 --> 00:25:05,120 Speaker 2: ground signal. You can do your can bus check. They're 483 00:25:05,200 --> 00:25:08,320 Speaker 2: under two hundred bucks. Brother, They're They're worth every penny 484 00:25:08,359 --> 00:25:10,639 Speaker 2: of it. All right, you're gonna you're gonna say how 485 00:25:10,640 --> 00:25:13,440 Speaker 2: did you get along without it? Beforehand?

Since we put 489 00:25:23,440 --> 00:25:25,919 Speaker 6: the new e c M in, I have not scanned it. 490 00:25:25,960 --> 00:25:29,159 Speaker 6: We just tried to crank it. Well, it's got but 491 00:25:29,280 --> 00:25:31,760 Speaker 6: it's got deft returnant incorrect. 492 00:25:31,800 --> 00:25:34,639 Speaker 2: Right, because because and I was gonna say with with 493 00:25:34,720 --> 00:25:37,960 Speaker 2: a new ECM in it, did you flash software? 494 00:25:39,160 --> 00:25:46,200 Speaker 6: Yeah? I actually got a mobile key locksmith come out 495 00:25:46,520 --> 00:25:48,639 Speaker 6: right programmed to feed back to the vehicle. 496 00:25:49,880 --> 00:25:52,439 Speaker 2: Well, but how did he communicate with the PCM if 497 00:25:52,480 --> 00:25:56,439 Speaker 2: it's got no if it's got no communications. 498 00:25:56,280 --> 00:26:00,840 Speaker 6: He used some little box in the laptop and actually 499 00:26:01,080 --> 00:26:03,520 Speaker 6: was talking to it. We couldn't get ours to do it. 500 00:26:04,960 --> 00:26:07,800 Speaker 2: So is he is he going through the OBD two connector? 501 00:26:08,880 --> 00:26:09,320 Speaker 6: Yeah? 502 00:26:09,400 --> 00:26:11,040 Speaker 2: Do you have the other PCM? And did you turn 503 00:26:11,040 --> 00:26:11,360 Speaker 2: it in? 504 00:26:12,640 --> 00:26:12,720 Speaker 3: Now? 505 00:26:12,800 --> 00:26:13,920 Speaker 6: We had to send it back. 506 00:26:18,760 --> 00:26:22,520 Speaker 2: One of those moments, all right. So the first problem 507 00:26:22,640 --> 00:26:26,280 Speaker 2: is why doesn't the PCM communicate with the scan tool? 508 00:26:27,240 --> 00:26:27,520 Speaker 3: Right? 509 00:26:28,280 --> 00:26:31,280 Speaker 2: So I'm going to send you down across Penn six 510 00:26:31,320 --> 00:26:36,440 Speaker 2: and fourteen. Do we have a CANbus problem? Where did 511 00:26:36,440 --> 00:26:39,440 Speaker 2: the PCM come from? Was it a GM reman? Was 512 00:26:39,480 --> 00:26:41,120 Speaker 2: it an aftermarket remen. 513 00:26:43,160 --> 00:26:45,440 Speaker 6: Come from flagships? The PM? 514 00:26:46,000 --> 00:26:47,960 Speaker 2: Why that doesn't mean anything to me? Is it a 515 00:26:48,000 --> 00:26:49,840 Speaker 2: GM dealer? Is it an aftermarket piece? 516 00:26:52,160 --> 00:26:57,080 Speaker 6: I guess they just repair and or reconditioned the computers, 517 00:26:57,119 --> 00:26:58,320 Speaker 6: the ACMs and send them back. 518 00:26:58,640 --> 00:27:02,600 Speaker 2: Okay. Do you have any experience with CANbus diagnostics? 519 00:27:02,640 --> 00:27:02,920 Speaker 3: Lee? 520 00:27:04,160 --> 00:27:07,760 Speaker 2: Okay, so I want you to get out a wiring 521 00:27:07,800 --> 00:27:12,200 Speaker 2: diagram for CANbus ever you ever? Does your repair shop 522 00:27:12,240 --> 00:27:14,000 Speaker 2: have a computer network in it? You have more than 523 00:27:14,000 --> 00:27:15,040 Speaker 2: one computer in the shop? 524 00:27:16,040 --> 00:27:16,280 Speaker 3: Yes? 525 00:27:16,359 --> 00:27:17,840 Speaker 2: Okay? How many computers you got? 526 00:27:18,640 --> 00:27:19,040 Speaker 6: Two? 527 00:27:19,160 --> 00:27:19,400 Speaker 5: Two? 528 00:27:20,160 --> 00:27:23,840 Speaker 2: So if you had three, all right, and the one 529 00:27:23,840 --> 00:27:26,760 Speaker 2: in the middle broke, you wouldn't be able to talk 530 00:27:26,800 --> 00:27:34,760 Speaker 2: to the third. You get that? So, so, which one 531 00:27:34,840 --> 00:27:39,120 Speaker 2: of the fourteen modules on this vehicle is possibly pulling 532 00:27:39,160 --> 00:27:43,720 Speaker 2: down the CANbus? Does that make sense to you? 533 00:27:45,320 --> 00:27:45,760 Speaker 6: Yeah? 534 00:27:46,040 --> 00:27:46,159 Speaker 5: So? 535 00:27:46,800 --> 00:27:49,680 Speaker 6: But now let me ask you this. I got another 536 00:27:49,800 --> 00:27:54,560 Speaker 6: traverse the same year, everything identical. I took the ECM, 537 00:27:55,000 --> 00:27:59,160 Speaker 6: the body control module, the agnission suites, the key cylinder. 538 00:27:59,280 --> 00:28:01,800 Speaker 2: Did you did you program it to your car? 539 00:28:03,160 --> 00:28:05,359 Speaker 6: No? No, no, no, We just stuck it into this 540 00:28:05,400 --> 00:28:07,440 Speaker 6: one and it wouldn't do nothing right. 541 00:28:07,520 --> 00:28:09,000 Speaker 2: Did you program it to that car? 542 00:28:09,840 --> 00:28:10,000 Speaker 3: Yes? 543 00:28:10,080 --> 00:28:11,520 Speaker 6: We tried to program it to this car and it 544 00:28:11,560 --> 00:28:12,720 Speaker 6: still wouldn't do anything. 545 00:28:12,480 --> 00:28:17,520 Speaker 2: Right because there's a can communication problem, right? Tell you what? 546 00:28:17,640 --> 00:28:19,280 Speaker 2: Sit tight? Let me pull over? Take this pause. I 547 00:28:19,280 --> 00:28:21,639 Speaker 2: don't want to rush it, but we're onto something here. 548 00:28:21,680 --> 00:28:23,400 Speaker 2: I'm running any in the car. Doctor. We'll be back 549 00:28:23,440 --> 00:28:46,000 Speaker 2: with Lee right after this. Hey, we're back, but you're 550 00:28:46,040 --> 00:28:48,840 Speaker 2: still there. What are you using in the shop for 551 00:28:48,880 --> 00:28:51,920 Speaker 2: information system? 552 00:28:52,160 --> 00:28:56,080 Speaker 6: I've got I try and Tanner and then the Mitchell software. 553 00:28:56,160 --> 00:29:00,440 Speaker 2: Okay, so go into Mitchell right, Go look at you're 554 00:29:00,480 --> 00:29:03,640 Speaker 2: looking at wiring diagrams. Go look at computer data lines. 555 00:29:05,080 --> 00:29:07,960 Speaker 2: All right, and if you understand this, just tell me 556 00:29:08,040 --> 00:29:10,160 Speaker 2: Ron no wrong path. I'll take it down a different leg. 557 00:29:10,200 --> 00:29:13,040 Speaker 2: But I want you to see this first. Okay, go 558 00:29:13,080 --> 00:29:15,479 Speaker 2: look at computer data lines. I've only got three minutes. 559 00:29:16,080 --> 00:29:18,959 Speaker 2: When you look at computer data lines, you're looking at 560 00:29:19,000 --> 00:29:22,000 Speaker 2: the network that connects the two computers in your shop, 561 00:29:22,440 --> 00:29:27,240 Speaker 2: capeche so. So if there's three computers in the shop 562 00:29:27,280 --> 00:29:30,120 Speaker 2: and four computers in the shop, every computer is a 563 00:29:30,160 --> 00:29:34,480 Speaker 2: module connected by a network cable. You're with me, yes, 564 00:29:34,840 --> 00:29:38,000 Speaker 2: go look at those computer data line wiring diagrams. When 565 00:29:38,040 --> 00:29:41,959 Speaker 2: you go across six and fourteen and they want sixty 566 00:29:41,960 --> 00:29:47,920 Speaker 2: oms of resistance. That shows integrity of the network because 567 00:29:47,960 --> 00:29:50,280 Speaker 2: if you look at it, there's a tan wire and 568 00:29:50,360 --> 00:29:54,480 Speaker 2: a tan with a black trace. That's the high speed network. 569 00:29:54,760 --> 00:30:01,600 Speaker 2: Below speed network, there's an Internet connection and a dial 570 00:30:01,680 --> 00:30:03,640 Speaker 2: up modem connection. Makes sense? 571 00:30:05,160 --> 00:30:05,440 Speaker 4: Yeah? 572 00:30:05,520 --> 00:30:09,520 Speaker 2: Okay, So across six and fourteen of the ald L 573 00:30:09,640 --> 00:30:11,520 Speaker 2: or the OBD two connector or whatever we want to 574 00:30:11,560 --> 00:30:14,640 Speaker 2: call it in our alphabetized industry, we want to see 575 00:30:14,680 --> 00:30:17,760 Speaker 2: we want to see sixty omes. If we don't have 576 00:30:17,920 --> 00:30:22,160 Speaker 2: sixty omes, why don't we have sixty omes? And then 577 00:30:22,680 --> 00:30:24,920 Speaker 2: if we were at the shop, I would I would, 578 00:30:25,000 --> 00:30:28,560 Speaker 2: I would which side looks more probable to be a suspect? 579 00:30:29,200 --> 00:30:32,600 Speaker 2: I would disconnect the electronic brake control module for example. 580 00:30:33,320 --> 00:30:36,120 Speaker 2: I would jumper the tan and the tan black to 581 00:30:36,120 --> 00:30:40,680 Speaker 2: put communication back. Do I now have data communication? Yes? Okay, 582 00:30:40,760 --> 00:30:45,080 Speaker 2: guess what I've got a short at EBCM. I don't. 583 00:30:45,680 --> 00:30:47,520 Speaker 2: I'm gonna leave it disconnected. I'm going to go on 584 00:30:47,560 --> 00:30:49,959 Speaker 2: to the next one. It all depends on the vehicle 585 00:30:50,000 --> 00:30:52,000 Speaker 2: and how the network is laid out. I want to 586 00:30:52,040 --> 00:30:54,479 Speaker 2: go to the first computer, then the second computer, then 587 00:30:54,520 --> 00:31:00,200 Speaker 2: the third computer and so on. Makes sense, right? Okay? 588 00:31:00,480 --> 00:31:02,680 Speaker 2: I want you to put this car, and I realize 589 00:31:02,680 --> 00:31:04,760 Speaker 2: you can't put the original PCM back in it because 590 00:31:04,800 --> 00:31:07,160 Speaker 2: you don't have it anymore. But I want you to 591 00:31:07,200 --> 00:31:10,040 Speaker 2: put as much of this car back together as normal 592 00:31:10,120 --> 00:31:13,960 Speaker 2: as you can, and then start looking at the computer 593 00:31:14,120 --> 00:31:18,640 Speaker 2: data network. Why don't you have communication on the CANbus? 594 00:31:19,080 --> 00:31:21,240 Speaker 2: Last thought? And I just want to point this out 595 00:31:21,240 --> 00:31:22,840 Speaker 2: because I just want to make sure I heard this right. 596 00:31:23,560 --> 00:31:28,800 Speaker 2: This car had an engine knock before all this started. Yeah, 597 00:31:28,960 --> 00:31:31,880 Speaker 2: So before you get buried too deep in this, obviously, 598 00:31:31,960 --> 00:31:33,840 Speaker 2: I'm sure you have. I've talked to you before. I 599 00:31:33,840 --> 00:31:36,400 Speaker 2: know you're a smart guy. You know we may be 600 00:31:36,520 --> 00:31:38,720 Speaker 2: fixing a car with a bad engine. 601 00:31:39,240 --> 00:31:42,200 Speaker 6: I've got a replacement engine that's going back into the car. 602 00:31:42,360 --> 00:31:45,400 Speaker 2: Okay, all right, all right, so then let's fix the 603 00:31:45,440 --> 00:31:49,000 Speaker 2: wiring issue first. All right, let's figure out why the 604 00:31:49,000 --> 00:31:52,720 Speaker 2: computer data lines don't communicate. Let's look at six and fourteen. 605 00:31:53,240 --> 00:31:54,760 Speaker 2: You may have to get on with a tech line 606 00:31:54,760 --> 00:31:56,239 Speaker 2: and they may have to walk you through pin by 607 00:31:56,320 --> 00:31:59,760 Speaker 2: pin testing. But why this doesn't have communication on the 608 00:32:00,040 --> 00:32:03,040 Speaker 2: on the data network is got to be the reason 609 00:32:03,080 --> 00:32:05,360 Speaker 2: why this car doesn't start, because that will hold up 610 00:32:05,400 --> 00:32:08,320 Speaker 2: the PCM that will put this car in theft, the 611 00:32:08,360 --> 00:32:10,360 Speaker 2: turrent and everything else that you're experiencing. 612 00:32:10,920 --> 00:32:13,120 Speaker 6: All right, kitto, sounds good? 613 00:32:13,200 --> 00:32:14,600 Speaker 2: You do that you need more? You know where to 614 00:32:14,600 --> 00:32:14,920 Speaker 2: find me? 615 00:32:15,720 --> 00:32:17,120 Speaker 4: Yes, sir, I appreciate it alrightly. 616 00:32:17,120 --> 00:32:20,000 Speaker 2: Anytime, Pal, anytime, Rod and Any and the car doctor 617 00:32:20,040 --> 00:32:22,360 Speaker 2: eight five five five six nine nine zero zero. We're 618 00:32:22,400 --> 00:32:41,800 Speaker 2: back right after this. Yeah, there we go all over 619 00:32:41,800 --> 00:32:45,440 Speaker 2: along with Rocky gms. You're calling over forty thousand break 620 00:32:45,480 --> 00:32:47,320 Speaker 2: fluid containers. I want to get this out before we 621 00:32:47,360 --> 00:32:49,920 Speaker 2: get out of here this week, General Motors, you're calling 622 00:32:49,920 --> 00:32:53,280 Speaker 2: more than forty thousand containers of ac Delco GM Dot 623 00:32:53,320 --> 00:32:56,480 Speaker 2: three breake fluid. They're calling tens of thousands containers after 624 00:32:56,920 --> 00:33:01,280 Speaker 2: federal regulators found certain batches may not meet acquired safety 625 00:33:01,320 --> 00:33:04,840 Speaker 2: standards and could contain visible sediment that may affect breaking performance. 626 00:33:04,880 --> 00:33:07,600 Speaker 2: The recall involved more than forty thousand units of ac 627 00:33:07,800 --> 00:33:11,080 Speaker 2: DELCOGMW dot three break fluid distributed in the United States, 628 00:33:11,080 --> 00:33:13,840 Speaker 2: according to a notice published on National Highway Traffic Safety, 629 00:33:14,320 --> 00:33:17,200 Speaker 2: GM decided in April to proceed with a non compliance 630 00:33:17,240 --> 00:33:20,880 Speaker 2: recall after completing its internal review and confirming federal testament results. So, 631 00:33:21,200 --> 00:33:23,320 Speaker 2: if you've got some ac Delco break fluid sitting on 632 00:33:23,320 --> 00:33:26,000 Speaker 2: the shelf and you've got your doubts, get it down 633 00:33:26,040 --> 00:33:28,200 Speaker 2: to your local GM store. I guess or you know 634 00:33:28,240 --> 00:33:31,400 Speaker 2: you can check the part numbers the recall. If you 635 00:33:31,440 --> 00:33:34,200 Speaker 2: think you've purchased bed break fluid from GM eight sixty 636 00:33:34,200 --> 00:33:37,360 Speaker 2: six four six seven ninety seven hundred, the recall number 637 00:33:37,600 --> 00:33:40,800 Speaker 2: is and is in Nancy twenty six twenty five fifty 638 00:33:40,840 --> 00:33:44,920 Speaker 2: two eighty three zero. But they also say it's based 639 00:33:44,920 --> 00:33:46,480 Speaker 2: on a date code, so you can find that out 640 00:33:46,520 --> 00:33:49,560 Speaker 2: through GM and just be aware of it. Nothing worse 641 00:33:49,600 --> 00:33:51,959 Speaker 2: than counting on a good break fluid. So, by the way, 642 00:33:51,960 --> 00:33:53,920 Speaker 2: it's speaking of accounting on I want to count on you, guys. 643 00:33:53,960 --> 00:33:56,200 Speaker 2: I do count on you guys, and I appreciate you guys. 644 00:33:56,440 --> 00:33:58,959 Speaker 2: I haven't given you the podcast numbers. Podcast numbers are 645 00:33:59,040 --> 00:34:00,760 Speaker 2: up once again. We had a three and a half 646 00:34:00,800 --> 00:34:04,640 Speaker 2: almost four percent climbing podcast numbers this week, so obviously 647 00:34:04,680 --> 00:34:06,920 Speaker 2: you guys are loving the social media. We're gonna continue 648 00:34:06,960 --> 00:34:09,120 Speaker 2: to do it next week. We've got some really great 649 00:34:09,160 --> 00:34:11,799 Speaker 2: topics coming up, one of which we're gonna be talking 650 00:34:11,840 --> 00:34:14,399 Speaker 2: about batteries and how to pick one till then till 651 00:34:14,440 --> 00:34:15,960 Speaker 2: the next time. I'm Ronn and Andy and the Car 652 00:34:16,040 --> 00:34:20,440 Speaker 2: Doctor reminding you good mechanics aren't expensive, they're priceless. 653 00:34:20,440 --> 00:34:22,920 Speaker 5: See ya, he's the car Doctor. 654 00:34:23,920 --> 00:34:25,600 Speaker 2: Carr advice to rite
