Air Bag Service Light

Hello. Is anyone having issues with the "air bag service light"? At 140 miles the abs sensor and bearing in the front passenger side went bad and the dealer had to replace it. The next 3700 miles with this truck were awesome but now I've been dealing with this air bag service light for the last 400 miles. I've already had the dealer look at it 3 times and they can't seem to fix it. The dealer inspected the wiring harness under the driver's seat and removed extra grease, then they replaced wiring harnesses, now they did some reprogramming and it's still acting up. There is nothing that triggers it, it just comes on when it wants to. I could be driving to the corner store and it comes on, stays on for about 10 - 15 seconds then it turns off. A mile down the road it comes back on for another 10 - 15 seconds then it turns off. I am beyond frustrated with this to say the least.

 

Any comments / suggestions / recommendations are greatly appreciated.

 

Thanks!

My guess would possibly be a bad seat sensor.

These trucks have six airbags and dozens of related components. It can be pretty much anything but based on their messing with the harness and de-greasing I'd bet some part is throwing a resistance error. If they've had the truck that many times I'd be asking to get GM involved.

My 2010 cobalt ss was a nightmare with the srs lights. It was always the little explosive thing in the passenger side seat belt tensioner that locks your belt if you crash. I replaced it 3 times and I payed for the last one as my warranty ran out. It was all over the cobalt forums and was well known to pop up. Anyways, I think there are quite a few gm cars out there now that have this issue with the passenger seat belt tensioner. It's not cheap to fix though when your warranty runs out, cost me 722 dollars installed. Ask the dealer to check the passenger seat belt tensioner and check the wires to see if the have been pinched or pulled (from being rotated).

2014 Sliverado airbag and stabltrack lights on my truck come on and off then the door bell rings. When this happened the airbag and stabltrack shut off. This happens every few minutes while driving. 3rd time in shop. Started around 3k miles.

Mine did the same thing after taking it to the dealer 4 or 5 times and then replacing everything you mentioned above and even replaceing the whole airbag I contacted gm and as crazy as it sounds they replaced the back plate on the seat and I haven't had a problem since

2016 GMC Sierra. Air bag warning light was coming on and off for a while till finally it stays on constantly, Took it in to the dealership and the service manager diagnosed the problem before reading the fault codes. He said it was most likely the passenger side seatbelt harness issue.  Sure enough, when the technician checked it out he was right. He informed they have seen this many times. My question is if its that big of problem why hasn't GMC issued a recall.

My buddy is looking at this 2015 Sierra with the same airbag issue. The current owner's son messed with it last year before being parked for a year. We'll check those list when start working on it next week. Got to finish installing the brake pads and nitto tires on the Wrangler before we can clear the garage.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.

      OCI, not when but why?

      I put the prof up. If you read what I posted. You can see that housing, cars and income are in line with the era we were talking about. It’s harder in some places easier in others. Let’s agree to disagree and put this back on track, OK? We both are pretty stubborn and hard headed. But I bring receipts. If you wish I will not respond to you in the future.

      Lets see if I can sum up two pages of nothing useful.    You want to refute your own governments data of the "Purchasing Power" Index FOR THE ENTIRE USA and its territories replacing it with the experience of a single family and its business and label that reality?  Then pound on that for a week hoping it will find traction?    Stan, I've told you several times. I don't do irrational. There are more people in the USA than your family.    I'm pretty sure this tread is so blown up. I'll give you a few days or months if need be to post yourself silent then I'll see if I can find enough parts of the train to reassemble it.

      VSE CCV Bypass - Anyone have this installed in their L5P?

      By asilverblazer · Posted

      Facebook groups hate VSE, poor customer service; their responses to criticisms are pretty poor for a reputable company. I'm not a customer, haven't bought anything from them, but how they handle themselves on social media is a definite "No" for me.

      Transmission Woes :-(

      By asilverblazer · Posted

      $10,000 for a transmission?   Pretty sure I could buy all the parts, tools, and education to rebuild it myself for a quarter of that amount.   or swap it out with a new one...
