Service Air Bag
2010 LNF, 32000 miles
Service Air Bag comes on every time I start my car and red airbag light stays lit on the dash. Any suggestions and/or recommendations other than taking it to stealership and paying to get it diagnosed?

It's a common issue with at least the TC Cobalts.. The Passenger Presence Sensor (PPS) in the passenger seat goes bad. So it shuts down the airbags, rather than failing to airbags on. Makes sense, right? Lol.
The dealership wanted over $800 to do mine. I laughed at them and walked away. That was 1.5 years ago.. I did find the PPS system on GMPartsGiant for less than $300. Either way, if you install it yourself, I think the dealership has to calibrate it.

How does one diagnose if it is the passenger seat sensor or not? Other than just making sure everything is plugged in? Would ScanXL pick this up by any chance?

It's def the passenger seat sensor, when I fondle the wires under the seat it sometimes trips. It doesn't always come on either. Sometimes when you start it'll be off and stay off, sometimes as you start it'll come right on, sometimes when you start it'll be off and then like 10 mins later it'll come on...
Anyone has an idea how exactly this sensor works to maybe service it or is replacement a MUST to fix?
Also, best place to find a replacement?

Its a common occurance for the cobalt TC. Happens all the time to me and the issue is a wire contact under the passenger seat. Whats happening is the wire gets pinched when the seat is slid back and forth. Pretty sure there is a customer letter for this. I never got it fixed cause its not really a problem worth letting someone else get in my car.
To make the light go off, turn the car off, open the driver door so everything completely shuts down. Start the car back up. airbag light goes away. Its a safety issue then GM should pay for and it should not be up to the customer to fix.

This bulletin is being revised to update the model years. Please discard Corporate Bulletin Number 09-09-40-003 (Section 09 - Restraints).
Condition
Some customers may comment that the SIR light is illuminated. Upon investigation, the technician may find the following SDM code stored:
DTC B0081 71: Passenger Presence System Invalid Serial Data Received With Passenger Presence System (PPS) Flash Code of DTC 023
Cause
The wire on the Belt Tension Sensor (BTS), that is part of the retractor assembly, may become open or acquire a ground near the sensor. If the BTS is rotated toward the rear of the vehicle, added stress is applied to the wire bundle that may cause an open or a ground path. The two photos below illustrate the possible effects on the wiring. Each photo indicates the area to investigate at the arrow labeled (1).

I checked all the wires under my seat and none are contacting anything nor damaged. I guess I'll have to rip my pillar panel off to get at e belt tension sensor. The light comes on for ten seconds, goes off for twenty, and repeats, over and over and over again. Super annoying, I wish the light would just stay on so my DIC is not flashing every two seconds.
