1 00:00:09,760 --> 00:00:11,560 Speaker 1: Well, I guess it's my turn to twelve eight five 2 00:00:11,600 --> 00:00:13,800 Speaker 1: to five five six zero nine nine zero zero. By 3 00:00:13,840 --> 00:00:16,680 Speaker 1: the way, T shirt sales are booming. I guess everybody 4 00:00:16,720 --> 00:00:18,840 Speaker 1: must have bought Ari Atomotive T shirts for mom for 5 00:00:18,960 --> 00:00:22,160 Speaker 1: Mother's Day. Now, that can't be it. Maybe Father's Day 6 00:00:22,239 --> 00:00:24,480 Speaker 1: is coming up. But yeah, get out the cardoctorshow dot 7 00:00:24,480 --> 00:00:27,440 Speaker 1: com if you're looking, and click on the merchandise button 8 00:00:27,480 --> 00:00:29,920 Speaker 1: like everybody else. So we're doing well, and don't forget. 9 00:00:30,120 --> 00:00:33,920 Speaker 1: Tomorrow fifteen Tacoma will appear in our YouTube feed around 10 00:00:33,920 --> 00:00:37,760 Speaker 1: three pm talking about that Fifteenthacoma with a fuel pump issue. 11 00:00:38,200 --> 00:00:39,919 Speaker 1: I think it's one of the better videos. We tried 12 00:00:39,960 --> 00:00:41,479 Speaker 1: a couple of different things trying to show you guys 13 00:00:41,520 --> 00:00:43,800 Speaker 1: a little bit of a variety of what we looked 14 00:00:43,800 --> 00:00:46,000 Speaker 1: at to fix that vehicle, and I think it's going 15 00:00:46,040 --> 00:00:49,040 Speaker 1: to do well. So that's tomorrow fifteenth Tacoma up on 16 00:00:49,159 --> 00:00:52,000 Speaker 1: a YouTube channel and we'll probably post it up to 17 00:00:52,000 --> 00:00:54,560 Speaker 1: Facebook two as well, although Facebook's getting a little funny 18 00:00:55,640 --> 00:00:57,720 Speaker 1: on how and what they allow, so but just know 19 00:00:57,800 --> 00:00:59,480 Speaker 1: that it's out on YouTube. Get out to our YouTube 20 00:00:59,520 --> 00:01:01,800 Speaker 1: channel run Nanny and the Car Doctor in case you 21 00:01:01,880 --> 00:01:05,080 Speaker 1: haven't let's uh, let's go to Joe in Pennsylvania. A 22 00:01:05,080 --> 00:01:08,640 Speaker 1: lot of Pennsylvania calls today, Palla, Hey Joe, how are you? 23 00:01:08,680 --> 00:01:09,600 Speaker 1: What can I do for you? 24 00:01:09,920 --> 00:01:14,560 Speaker 2: Yes, good afternoon. Yes, this impalla. It has a different 25 00:01:14,640 --> 00:01:18,399 Speaker 2: kind of console shifter than what's listed on YouTube. And 26 00:01:18,400 --> 00:01:20,920 Speaker 2: there's no real release button on you have to play 27 00:01:20,959 --> 00:01:23,080 Speaker 2: with and you have to push up and down on 28 00:01:23,080 --> 00:01:26,520 Speaker 2: a solenoids sometimes to get it out of park. And 29 00:01:26,520 --> 00:01:30,160 Speaker 2: what's bad about this? Ron as Triple A refuses to 30 00:01:30,160 --> 00:01:33,560 Speaker 2: tow a car when it's stuck in park. Interesting, they 31 00:01:33,600 --> 00:01:35,640 Speaker 2: will not do it. They're afraid that they're going to 32 00:01:35,720 --> 00:01:37,000 Speaker 2: damage the transmission. 33 00:01:37,280 --> 00:01:38,920 Speaker 1: Interesting, what do they do? What do they do if 34 00:01:38,920 --> 00:01:40,480 Speaker 1: it's really stuck in park and you're stuck on. 35 00:01:40,480 --> 00:01:42,360 Speaker 2: The side of the road, Wait till the next day 36 00:01:42,400 --> 00:01:45,600 Speaker 2: until somebody comes out with a dolly or whatever. I yeah, 37 00:01:45,640 --> 00:01:48,560 Speaker 2: it's crazy, it's ridiculous. I'm sure you've come across it. 38 00:01:48,600 --> 00:01:52,600 Speaker 2: Even the local dealer here said he wouldn't do much 39 00:01:52,600 --> 00:01:56,080 Speaker 2: for it because it's intermittent. Well, should I do buy 40 00:01:56,120 --> 00:01:57,120 Speaker 2: a solenoid for it? 41 00:01:57,200 --> 00:01:59,760 Speaker 1: Under no, So let's let's let's talk about this. Let's 42 00:02:00,040 --> 00:02:03,640 Speaker 1: I'm gonna make some assumptions of generality. Okay, so allow 43 00:02:03,760 --> 00:02:07,200 Speaker 1: me that. All right, So this is a this is 44 00:02:07,240 --> 00:02:10,600 Speaker 1: a ten Impala with a three five right right, and 45 00:02:10,600 --> 00:02:13,720 Speaker 1: and the automatic trends won't come out of park exactly. 46 00:02:13,960 --> 00:02:16,880 Speaker 1: So when it when it fails, when it won't come 47 00:02:16,919 --> 00:02:19,680 Speaker 1: out of park, do you know if the brake lights work? 48 00:02:21,360 --> 00:02:25,680 Speaker 2: Uh, they fixed it once they put used parking. They 49 00:02:25,720 --> 00:02:28,239 Speaker 2: put another brake light switch on it too, I guess 50 00:02:28,280 --> 00:02:31,240 Speaker 2: and see I bought it from a rebuildable place. 51 00:02:31,000 --> 00:02:34,799 Speaker 1: And it was a car because because that's critical. All right, 52 00:02:35,240 --> 00:02:38,720 Speaker 1: if the brake lights work, here's what happens. Right, Joe 53 00:02:38,760 --> 00:02:41,200 Speaker 1: gets in the car, He steps on the brake pedal, 54 00:02:42,200 --> 00:02:44,840 Speaker 1: The brake lights light up. Joe turns the key on 55 00:02:46,000 --> 00:02:49,640 Speaker 1: the the The brake lights switch completes and sends power 56 00:02:49,800 --> 00:02:53,880 Speaker 1: up to the body control module. All right, The body 57 00:02:53,919 --> 00:02:58,000 Speaker 1: control module sees the brake input request. It thinks Joe 58 00:02:58,080 --> 00:03:02,480 Speaker 1: wants to shift out of park because it sees it 59 00:03:02,520 --> 00:03:05,920 Speaker 1: also sees park on the on the trans side of life, 60 00:03:07,040 --> 00:03:10,320 Speaker 1: and it'll it releases the solenoid. It sends power out 61 00:03:10,360 --> 00:03:12,640 Speaker 1: on a separate wire. It sends wire. If you go 62 00:03:12,680 --> 00:03:15,080 Speaker 1: down to that shift solenoid, there's a dark green wire 63 00:03:15,120 --> 00:03:16,000 Speaker 1: with a white tracer. 64 00:03:17,840 --> 00:03:20,960 Speaker 2: And there's it's different than the ones on the YouTube video. 65 00:03:21,000 --> 00:03:23,760 Speaker 2: It's totally different. Even the dealer I went for a 66 00:03:23,800 --> 00:03:26,440 Speaker 2: technical service ball and it's totally different with this. 67 00:03:26,520 --> 00:03:28,080 Speaker 1: How's it totally different? 68 00:03:28,880 --> 00:03:31,040 Speaker 2: It doesn't have a release button on the side. 69 00:03:31,400 --> 00:03:34,400 Speaker 1: No, no, no, no, forget that. Look at wiring color? 70 00:03:35,200 --> 00:03:37,840 Speaker 1: All right? Do you are you taking this? Are you 71 00:03:37,880 --> 00:03:39,480 Speaker 1: taking this console apart on your own? 72 00:03:39,560 --> 00:03:43,560 Speaker 2: Joe? Yes, I took it off because okay. 73 00:03:43,360 --> 00:03:46,600 Speaker 1: So when you when you look at the shift control solenoid, 74 00:03:47,120 --> 00:03:49,800 Speaker 1: what color are the two wires at the solenoids? 75 00:03:50,360 --> 00:03:53,400 Speaker 2: Yes, I believe there's a green one there, right, So. 76 00:03:53,560 --> 00:03:57,000 Speaker 1: The dark green wire with the white tracer, and listen, 77 00:03:57,680 --> 00:04:00,040 Speaker 1: learn how the circuit works when it's working. Will you 78 00:04:00,080 --> 00:04:00,840 Speaker 1: do me that favor? 79 00:04:02,200 --> 00:04:07,960 Speaker 2: So? Yeah, with the deal or, they said the switch 80 00:04:08,160 --> 00:04:12,680 Speaker 2: was working, okay, great, another problem was working all right? 81 00:04:12,760 --> 00:04:15,680 Speaker 1: So so but hear me out, all right, I want 82 00:04:15,720 --> 00:04:17,400 Speaker 1: you to put your foot on the brake, turn the 83 00:04:17,480 --> 00:04:20,039 Speaker 1: key on, and check voltage at that dark green wire 84 00:04:20,080 --> 00:04:24,000 Speaker 1: with the white trace. That should be battery voltage. Then, 85 00:04:24,160 --> 00:04:28,360 Speaker 1: with the meter still attached to that dark green, white wire, 86 00:04:29,240 --> 00:04:31,240 Speaker 1: take your foot off the brake, pedal. You should see 87 00:04:31,240 --> 00:04:34,640 Speaker 1: battery voltage go to zero. That shows you that's the 88 00:04:34,720 --> 00:04:39,520 Speaker 1: working wire. You with me so far? Yes, Okay, when 89 00:04:39,560 --> 00:04:42,960 Speaker 1: the problem happens, do we have power on that dark 90 00:04:43,000 --> 00:04:49,280 Speaker 1: green white? First question? Absolute, first question. If we have 91 00:04:49,360 --> 00:04:52,480 Speaker 1: power on that dark green white. We've just eliminated seventy 92 00:04:52,520 --> 00:04:56,839 Speaker 1: five percent of the circuit. Now we're down to it's 93 00:04:56,880 --> 00:05:01,360 Speaker 1: either the solenoid or the ground. Which is the other 94 00:05:01,400 --> 00:05:02,760 Speaker 1: wire coming out of the solenoid. 95 00:05:04,080 --> 00:05:06,200 Speaker 2: Well, a couple of times I had to press in 96 00:05:06,240 --> 00:05:08,520 Speaker 2: on the solenoid itself to get it gone. 97 00:05:08,839 --> 00:05:11,719 Speaker 1: I understand that, but that's not testing it. I'm talking 98 00:05:11,720 --> 00:05:16,880 Speaker 1: about how to test it. Okay, are you able to 99 00:05:16,920 --> 00:05:18,040 Speaker 1: test You have a vault meter? 100 00:05:18,279 --> 00:05:20,520 Speaker 2: Yes, I have many of them. Yeah. Okay. They mentioned 101 00:05:20,560 --> 00:05:26,080 Speaker 2: there's wiring faults and problems with wire routing, but that 102 00:05:26,279 --> 00:05:27,320 Speaker 2: all looked okay. 103 00:05:27,360 --> 00:05:30,400 Speaker 1: Well, but you have to catch it, Joe. You have 104 00:05:30,480 --> 00:05:35,400 Speaker 1: to catch it in the act. All right, it's intermittent. Now, 105 00:05:35,760 --> 00:05:41,919 Speaker 1: you could you could run a new wire out of 106 00:05:41,920 --> 00:05:44,000 Speaker 1: the BCM. But what you want to do is if 107 00:05:44,040 --> 00:05:45,880 Speaker 1: you catch it in the act where you're stepping on 108 00:05:45,920 --> 00:05:49,720 Speaker 1: the brake pedal switch and you have no power at 109 00:05:49,720 --> 00:05:53,720 Speaker 1: that dark green white. Trace it back, get a wiring 110 00:05:53,760 --> 00:05:58,359 Speaker 1: diagram that dark green white goes direct to the body computer. Okay, 111 00:05:58,520 --> 00:06:01,200 Speaker 1: those wires have been known to break there. They make 112 00:06:01,240 --> 00:06:03,640 Speaker 1: a couple of tight turns as they come out. They 113 00:06:03,640 --> 00:06:06,320 Speaker 1: have been known to break internally, and sometimes replacement of 114 00:06:06,360 --> 00:06:09,240 Speaker 1: that wire does the trick. Sometimes this is a BCM 115 00:06:09,680 --> 00:06:16,920 Speaker 1: the actual computer itself, all right, the dish right, Well, 116 00:06:16,960 --> 00:06:19,280 Speaker 1: it doesn't matter where it is. It's it's We can't 117 00:06:19,279 --> 00:06:22,719 Speaker 1: wish it was somewhere easy. Now, the other question I've 118 00:06:22,720 --> 00:06:24,839 Speaker 1: got is when they put a brake light switch in it, 119 00:06:25,839 --> 00:06:28,440 Speaker 1: I wonder if they did a brake pedal position calibration. 120 00:06:31,760 --> 00:06:35,160 Speaker 1: They call it a b A Baker Paul Paul BPP, 121 00:06:35,880 --> 00:06:39,440 Speaker 1: a BPP calibration, and you just scantal to do that. 122 00:06:39,600 --> 00:06:43,000 Speaker 1: And if they didn't do that, it will replicate the 123 00:06:43,040 --> 00:06:45,960 Speaker 1: same problem as a bad break light switch. The computer 124 00:06:46,120 --> 00:06:50,000 Speaker 1: needs to learn pedal position and a new switch replacement 125 00:06:53,360 --> 00:06:53,919 Speaker 1: makes sense. 126 00:06:54,440 --> 00:06:57,360 Speaker 2: Well, so I can't just go bypassing it all the time. 127 00:06:57,400 --> 00:06:58,240 Speaker 2: That's going to get old. 128 00:06:58,320 --> 00:07:00,520 Speaker 1: It, well, it's gonna get older. It's going to get 129 00:07:00,520 --> 00:07:04,000 Speaker 1: old very quickly. This isn't listen, This isn't the hardest 130 00:07:04,000 --> 00:07:06,360 Speaker 1: problem in the world to solve, somebody's got to sit 131 00:07:06,400 --> 00:07:09,240 Speaker 1: down and understand how the circuit works. And that's that's 132 00:07:09,279 --> 00:07:11,840 Speaker 1: all I'm asking you to do, all right. This is 133 00:07:11,840 --> 00:07:14,559 Speaker 1: a simple solenoid. It's a power in the ground. Power 134 00:07:14,600 --> 00:07:17,600 Speaker 1: comes out of the BCM. BCM looks at you know, 135 00:07:17,680 --> 00:07:20,080 Speaker 1: breake pedal switch for input. It looks at park position 136 00:07:21,040 --> 00:07:24,120 Speaker 1: because it sees it sees park position when you move 137 00:07:24,200 --> 00:07:28,360 Speaker 1: the shifter. There's an indicator on the dish right park, reverse, neutral, 138 00:07:28,440 --> 00:07:31,960 Speaker 1: drive and so on right, So that's because the shifter 139 00:07:32,160 --> 00:07:34,360 Speaker 1: is talking to the body computer, which is talking to 140 00:07:34,360 --> 00:07:37,200 Speaker 1: the instrument panel. What I'm trying to point out is 141 00:07:37,520 --> 00:07:39,840 Speaker 1: this isn't a straight shot where the brake pedal switch 142 00:07:40,280 --> 00:07:42,880 Speaker 1: moves that solenoid. The brake pedal switch puts input to 143 00:07:42,920 --> 00:07:45,760 Speaker 1: the BCM. The BCM looks at other conditions. If they're 144 00:07:45,800 --> 00:07:48,400 Speaker 1: all set, it sends voltage out that dark green white 145 00:07:48,400 --> 00:07:50,720 Speaker 1: over to the shift solenoid. The shift solenoid pulls in. 146 00:07:51,160 --> 00:07:53,280 Speaker 1: It's simple, it really is. 147 00:07:53,400 --> 00:07:56,640 Speaker 2: As Chevy Dealer said, they wouldn't be able to fix it. 148 00:07:57,080 --> 00:08:01,920 Speaker 1: Listen so far well, and that it's true, okay to 149 00:08:01,960 --> 00:08:04,840 Speaker 1: a degree. Or somebody's got to take the bull by 150 00:08:04,880 --> 00:08:08,520 Speaker 1: the horns. How about how about this? How easy is 151 00:08:08,520 --> 00:08:13,160 Speaker 1: it to get to that dark green white wire? Okay, 152 00:08:13,280 --> 00:08:15,880 Speaker 1: I go down to your local lotapart store, buy a 153 00:08:15,920 --> 00:08:18,760 Speaker 1: one ninety four bulb. Go go get a little sidemark 154 00:08:18,840 --> 00:08:23,160 Speaker 1: or bulban socket. Cut the dark green white wire, put 155 00:08:23,160 --> 00:08:25,640 Speaker 1: the bulb in between. Cut the dark green white wire 156 00:08:25,640 --> 00:08:27,920 Speaker 1: in a place where you can easily solder it back together. 157 00:08:28,520 --> 00:08:31,119 Speaker 1: All right, Now, every time you step on the shift 158 00:08:31,200 --> 00:08:36,240 Speaker 1: or what's going to happen. If the system's working, it 159 00:08:36,240 --> 00:08:36,679 Speaker 1: should light. 160 00:08:37,559 --> 00:08:38,640 Speaker 2: You should also hear it. 161 00:08:39,000 --> 00:08:39,920 Speaker 1: Well, you'll hear it. 162 00:08:39,960 --> 00:08:41,520 Speaker 2: They've had that system early. 163 00:08:42,200 --> 00:08:47,480 Speaker 1: Joe, Joe, You're you're looking too far ahead. Okay, I 164 00:08:47,840 --> 00:08:49,959 Speaker 1: love you. You remember the car doctor Nation, but you're 165 00:08:50,000 --> 00:08:52,959 Speaker 1: looking too far ahead. I'm talking about diagnosing. You're talking 166 00:08:52,960 --> 00:08:56,320 Speaker 1: about expected results on something else. If that bulb lights 167 00:08:56,559 --> 00:08:58,760 Speaker 1: and you don't hear the click, yeah, then you've either 168 00:08:58,800 --> 00:09:00,960 Speaker 1: got a ground or a solenoid issue. I'm trying to 169 00:09:00,960 --> 00:09:04,880 Speaker 1: tell you how to prove it. All right, If you 170 00:09:05,920 --> 00:09:08,559 Speaker 1: if you push on the brake pedal and it does 171 00:09:08,679 --> 00:09:13,959 Speaker 1: not light, where's the problem that's in the wir ring 172 00:09:14,160 --> 00:09:18,440 Speaker 1: or the right or the brake light switch input because 173 00:09:18,480 --> 00:09:23,520 Speaker 1: they didn't do a BBP calibration. You get what I'm saying. 174 00:09:24,920 --> 00:09:26,800 Speaker 2: All Right, I guess I'll have to do all that 175 00:09:26,960 --> 00:09:33,000 Speaker 2: because I'm afraid i'm gonna get stuck permanently. So all right, Joe, 176 00:09:33,640 --> 00:09:34,880 Speaker 2: all right, thank you very much. 177 00:09:34,880 --> 00:09:36,920 Speaker 1: You're very welcome, sir. You'll be well. I'm running any 178 00:09:36,920 --> 00:09:38,520 Speaker 1: in the car, doctor, I'll be back right after this
