air bag light 2004 deville


Recommended Posts

You need to check to see if any DTC codes are set. For the light to be on, a diagnostic code must have been set. You need a reader that will dump body codes or have your local Cadillac dealer retrieve the code for you, but I did find this:

Service VME - Service Air Bag Message - kw SIR SDM MIL DTC sensor module seat lamp light cover GMT800 GMT805 GMT806 GMT820 GMT830 #PIT3036 - (Jun 24, 2004)

Service VME - Service Air Bag MessageThe following diagnosis might be helpful if the vehicle exhibits the described in the PI.


VSSM bulletin board message

Some customer may comment that the Service Air Bag light comes on and the issue is related to the Passenger Presence System. In these cases, it is necessary that technicians utilize all three parts in the service module kit ( PPS module, PPS sensor and pad and the seat foam) because of the calibration involved. A recent review of returned parts appeared to indicate that not all parts of the kit were being used.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance.
