I do only have this with a friend's truck, and it started . It looks like a little stereo booster down there below the stereo and I believe it was only 2 of the connecters that come off. I'll look for the correct video and post it. I have a caddy with OnStar and no problems with it. Not sure why there is a difference. Although OnStar still answers in the 2002 caddy. Kinda freaky

Same here just got a 09 Chevy Silverado it's doing the same thing

I can't even drive a Chevy vans electrical nightmare. I'm trying to solve suburban parasite

​@_123mrkrabz it's not a computer but a sdm or a airbage I guess computer of sorts n yes it's under the driver's seat and capet

Good luck....it drove me crazy for awhile and never saw a good explanation so figure a video could only help.

So this solved your problems

i am having multiple electrical codes on my 2009 Silverado. Can I just unplug it or do I need to replace it?

did u end up changing the SDM airbag module?

What was the problem?

Dude says he got it fixed but doesn’t even mention what he did smh

​@@TorresBoxingsame thing in the video as he stated thanks to the video he got it fixed.

Unplug radio . See if problems go away . Get new radio

What harness did you unplug?

@@johnnybobgoldstein2823 under drivers seat, unplug the airbag module

Well of course it is!

Do you know what exactly it was called I'm having similar issues in gmc sierra 4.8liter 2008?

Planned obsolescence

Best of luck!

Just received my notice of a recall, thank goodness I ran across this video

Hey gereta bridges, so just with the recall you was able to take it to gm and get it fixed? How much was it? Im having the same problem

Ya I had a booked appointment for the recall, they pushed it back 2 weeks the day of. I didn’t know it might leave me stranded in the mountains

What is tmc

@@deseraydugan8795 I meant to say TCM. Transmission Control Module. I know that doesn't make sense with all the other unrelated issues going on, but it's possible that they have all of that stuff tied together some way. It's all about making you take it back to them. If your service engine light is on, have a friend or a part store like AutoZone to hook up a obd scanner to it. That way if you take it to the shop you can tell them that you hooked up a scanner to it and that's what it told you. If you sound like you half way know what you're talking about, they're less likely to try to pull a fast one on you. By the way, taking it to a GM dealership is not necessarily your best option. Find out about the mechanics that work where you're taking it. A privately owned shop fixed mine. This problem was not just in the Tahoe, but all GM trucks in 07, according to blogs I read and videos I watched.

Did your door locks -lock and unlock at the same time ? And when my happens I can drive approximately 7mph

@@vjsm4102 I had that too, but it stopped after I pulled the negative battery cable for 24 hours. As for the speed, it sounds like your truck is in limp mode. If the app sensors are not functioning properly they will send the wrong signal to the computer. They sense the pressure you're putting on the pedal and tell your car how fast to go. I found out about the app sensors when I had the reduced engine power mode in my 2003 trailblazer. See the pattern here? 🤦 There was nothing wrong with the speed cables that they used in the 80s and 90s.

@@dbeene36 yeah it's goes haywire. Yesterday the truck was running and locked and unlocked my door on the inside and it stopped the truck.it only happens every couple weeks.

try pulling any codes? checking grounds like the battery to block and chassis, ground strap from block to chassis on driver side, now this abs module thats under the driver seat is what im checking next on my rig. Hope its not the BCM, but assuming bad grounds in various places all over the vehicle are causing issues with all the computers in these year GM's. good luck.

I will try this also thanks

Yeah buddy you ain't lying

100%

The engineering guys we’re thinking not thinking just attached the worst spot for human that’s a imbosible to reach lol the ground wire

The devil GM

It is like my Sierra 1500 regular cab was designed by jokers. The AC turns on whenever the cabin recirculate switch is pressed. It has a switch for the AC, that does not work when in recirculate mode is active. WTF? The seat back release only moves the seat back forward 4 inches. WTF? The jack tools are located in the middle behind the seats and are difficult to access or reinstall. If you weight more than 200 pounds, good luck getting to it. WTF? The plastic hub cap nut become loose. So if you forget to tighten them periodically, the hub cap will fall off. Also, they are plastic, so don't over tighten them. WTF?

Good luck. Its how they make money off you!! And to put it under carpet where it gets wet and humid and hard to dry out is mone in the bank for them!

Check your negative battery terminal for a good connection. Check each leg where it ends. One leg ends on the block and the other under the radiator near the passenger side. If all of those are good check the positive cable from the mega fuse to the main fuse box under your hood. The connection snaps into the bottom of the fuse box housing. It can get loose and smash the female side. I have a 2009 Silverado same issue. It was a bad negative terminal connection.

@@danclark5161 I have a 2007 Tahoe and my Back lights on my cluster are Flickering. Any suggestions?

@@danclark5161 all the same problems. Changed negative cables. Worked well for a bit. Now its doing it again!

@@lindsaymarie7238 replace FSCM fuel system control module. Its a computer that talks to all of the other modules. Located drivers side rear just to the drivers side of the spare tire. Under the bed of the truck. Get a new one and have it programmed to your trucks VIN#.

@@danclark5161 will definitely try that next. Im soooo ready to sell the damn thing for parts!!!! Lol

I wanna say that’s for the passenger airbag.. not totally sure tho

It's to reset your trip meter

@@lakesuperiordownrigger1133 I do mine electronically holding down the one if the dic buttons. Is this a manual option then?

Check codes.... bet its a BCM

adan Sandoval hey how did you solve the issue, going through it with my 08 Rado as well

Trying wiggling your negative battery cable and see if it starts. mine will act dead and sometimes click, then I wiggle the negative battery cable and that gets it to start. In already replaced the starter and battery last year and it worked for a while, I think it’s just the dumb ground battery cable.

@@nickk4010 I replaced all that, even negative battery cable. Worked well for a bit, then started all over again. So fed up. Chevy dealer said nothing is wrong, 2 other shops say 2 different things, and 2 mechanics said other crap, new solenoid put on...so sick of this. How the hell do we all have the same problems, but still mechanics don't have answers?!?!?

I’ve spent $3500 and still no crank lol

Did u figure out? I have a 09 avalanche too having same issues

I'm totally doing this today, thanks. I hope it works

@@tiger9racing779 did it work?

@@bigtrev7103 For me it did not. But now I have bigger problems. Lifters in cylinder 4 are dead. Im blaming that stupid ass AFM/DOD. Im at 200k

@@bigtrev7103 No

I hope you deleted that crappy thing

I think a reflash is needed

@@jagriv5659 bcm was fried installed a new one tho

​@@jagriv5659wtf is a reflash

what do you mean by writing that Onstar needs to be disconnected, what is it, I have the same problem, the car won't start :(

Below the stereo is the OnStar unit. After years it ends up disabling the ignition. It's Ina u tube video . That's what it was . You have to dig a little.

Why so they can just blow up out of know where and possibly catch fire and 2021-2023 Kia k5 are having to do recall on the whole wiring harness at least with Chevy you get 100k or so before these problems

Same problem with my truck but in my case are all the lights

It was about $800 at a chevy dealer...🤢

I saw the airbag recall would it fix all the radio issues and tire pressure problems?

@@aaronbishop2786 I don't know , I had no issues when they did the recall way back when

@@aaronbishop2786 when I got mine fixed by the dealer my radio was and is working good but that didn't fix the TPM or tire pressure monitors . I have 2 on the driver's side that I think all is wrong is the batteries are dead now . A year ago they would work perfectly when warm out but when fall came ( I live in Wisconsin) and it got down to freezing the 2 on the driver's side would either work some times or not . As of typing this now both stopped working so I think the batteries are dead in those 2 . There are videos on KZfaq hear showing they can be changed out the batteries that is but you have to cut the case open then replace the batteries and silicone them back together again which to me I could do it easily enough but I think I would rather buy new ones that come with a warranty and be done with them . These TPM can also start to leak air when they go bad so if the tires on the ones not working are slowly loosing air it's because of the TPM valve is going bad and leaking .

It was.. explanation is in the video.. that truck issue was horrible! Good luck

What part change i got same problem

@@3082cuevas sdm airbag module located under the driver seat and carpet. Good luck!

Just had mine replaced & programmed and the problems are still there. Both positive and negative battery cable near the post have exposed and slightly corroded wires. Heard this is a issue from manufacturer. Just replaced a corroded mega fuse and cleaned the connectors. Not sure if any of this is actually the cause....

I have a Chevy Silverado 2009 2500hd 6.0 gas a couple days ago I was driving and a code started saying reduced engine power while driving so I stoped . I used a check engine to erase the codes it was throwing at me . I believe I have a short somewhere Becuase when I turn my left blinker on my interior lights will blink n dim at the same time .

Mine is an 07. I call it the Bail out edition.

They thought that building obsolescence into the company that it would somehow benefit it.

630 to find out where the problem is. 70 to fix it

Do you have a pic or video with some info? My truck just started this crap to! Lost speed and rpm airbag lit up no temp or oil pressure

Yes! Deep yooper

@@lakesuperiordownrigger1133 I'm a troll unfortunately lol. I'd run further north but we need to make a line here to keep them out of GODS country.
