Default Airbag light fix HELP

recently purchased an 07 bas coupe and while driving home the airbag lite came on. I adjusted the seat several times before driving so assumed the connector may have loosened. I removed the seat and disconnected, ,used dielectric grease and put back together using wire ties. Started car back up and lite still on. I checked 10amp fuse and it was good. Actually put a 15 in to check and still on. I pulled the fuse completely and lite stayed on????? Any ideas what to try next or is this like the check engine light where you have to drive a bit to turn off? Thanks for any advice

Check the passenger side connector also.

Pull the airbag code(s) to know what the computer is objecting to. Everything else is guessing.

Requires a GM airbag-aware scan tool such as a Tech 2 or a better-than-generic 3rd party scanner.

You should not use dielectric grease especially on the airbag system…this grease is an INSULATOR and the SRS wiring has a VERY low resistance !!…scan for codes first if you can !!

There is a service bulletin on the problem. But it has a repair period and I think you are over it in time. Had my 11 in and was told it involved 2 harnesses and wiring fitting up higher into seat bottom.

The GM repair is basically they cut the connector out of the system and solder the wires together to make a hard connection. Which works great until the day you want to remove one of your seats for any number of reasons.

As I understand TSB 15643A, the problem is that the connectors hang down low enough to touch the carpet. The fix is to cut off the connectors and splice in new pigtails, moving the location where the connectors meet. This adds about a foot to the car side of the harness so that the connectors can secured further away from the carpet.
