About 3 months ago, my air bag light came on and stayed on after I was doing a winch demonstration for Search and Rescue. Took it to a friend with a diagnosis computer (I have an HP Tuner, but no way of scanning the BCM) - who said the code was the roll over sensor had a fault.
Because I get reimbursed for damage done during missions and training, I then took the vehicle to the local, former Hummer dealership for diagnosis and fixing.
They said the roll over sensor was bad. I paid to have them test the system before we replaced it as this was a ~600 repair (with parts). They said it was the roll over sensor. I replaced the roll over sensor - and they gave me my old roll over sensor back. The mechanic said there was an electrical fault in the sensor...
Maybe it was, and maybe the system has two faults. The light came back on a week ago, so back to the dealership I went. They pulled the code, which said passenger side air bag didn't have proper resistance. He (mechanic, who I really like) pulled the glovebox out in the waiting area of this Cadillac dealership and tried to wiggle the plug to get good contact. No joy - unfortunately, at the same time he was playing with that, somehow he managed to disconnect the sat radio antenna...
Anyway, I took the car back for a real appointment because the light stayed on. He pulled the entire dash apart and tested - and found the light went off when he plugged his testor into the plug for the passenger airbag.
Yesterday I picked my H3 up and the light was on again. The mechanic had cycled the ignition 10x, it would have been 13x when it came back on. The suggestion is replace the passenger air bag.... but I'm reluctant. From a global view there's two questions: 1) was the rollover sensor actually bad, and/or 2) is there a fault with the airbag as well as with the old roll over sensor?
I'm hesitating to talk to the dealership because I don't want to get the mechanic in trouble - as I said, this guy has been super helpful on all manner of issues with my H3; and getting him in trouble just isn't something I want to do.... however, we'll be at $1,500 in repairs and counting if I replace the airbag.... part of me is considering finding out what resistance the airbag computer is looking for and putting in a resister instead of plugging into the airbag.... I'm not a fan of airbags anywhere but in the steering wheel....
Thoughts?
