[WHOSNEXT]

After adding video to my stock nav/dvd radio and got everything back together, I am now getting SERVICE AIR BAG??? Is there a way to reset this? I did take the dash apart, is there anything I can check?

If you had An airbag connector disconnected while doing your work and the key on it will set A code. I was repairing A radio for no audio and had the key on with some airbag connectors unplugged and the police showed up at the dealer, onstar contacted them and they thought there was an airbag deployment accident, when onstar attemted to contact me there was no response due to the radio was in-op.

I did disconnect a couple of connectors, you would think there was a way to reset them?

If there is no current problem the light should go out after A predetermined amount of ignition cycles, not sure how many without knowing what code is set and I haven't read any air bag diagnostics in A while, but should be out after 10 cycles, if not I would get it scanned. Have A read on this TSB.
Subject: Info - DTCs B1001, B1271 or B1780 Set When Replacing/Reprogramming Other Modules #02-09-41-001 - (05/24/2002)



Models: 1999-2003 Passenger Cars and Trucks

with Class 2 Serial Data Communication Between Modules



--------------------------------------------------------------------------------

This bulletin is being revised to add model years and reflect changes in the Tech 2 procedure and filing classification. Please discard Corporate Bulletin Number 99-06-03-010A (Section 6 -- Engine).


--------------------------------------------------------------------------------

Class 2 Serial Data Communication allows control modules (i.e. the Powertrain Control Module (PCM), the Body Control Module (BCM), the Dash Integration Module (DIM), the Instrument Panel Cluster (IPC), the radio, the Heating, Ventilation and Air Conditioning (HVAC) Controller, and the Sensing and Diagnostic Module (SDM) to exchange information. This information may be operational information or identification information. Among the identification information exchanged and compared within these modules is the Vehicle Identification Number (VIN). Typically the one module, the master module, broadcasts the VIN and all the other modules compare the VIN stored within itself. When the broadcast VIN does not match the VIN stored within the SDM, the following actions occur:

• DTC B1001 Option Configuration Error is set and deployment of the airbags is inhibited.

• DTC B1271 or a DTC B1780 Theft Locked.

The VIN information is also used by the radio. When the VIN does not match the VIN stored within the radio, DTC B1271 or DTC B1780 is set and the radio is inoperative.

Additionally, the master module will compare the SDM's part number (last four digits) to determine if the correct SDM is installed in the vehicle. If the SDM is the wrong part, a B1001 will also set.

This situation may occur when a vehicle is being repaired. When a PCM or a body control type module is replaced, the VIN information must be programmed into the replaced (new) control module. A module which has had VIN information entered into it (for example, one taken from another vehicle) cannot be reprogrammed. VIN information can only be entered into new modules. The ignition must be ON in order to program the control module. Since the VIN information is broadcast when the ignition goes to ON from any other ignition switch position, DTCs may be set in the SDM and/or the radio. Therefore, always follow the specified control module replacement procedures.

After completing the repair, turn OFF the ignition for at least 30 seconds.
Turn ON the ignition and check for DTCs using a Tech 2® scan tool.
If DTCs B1001, B1271, or B1780 are present with a history status, DO NOT REPLACE THE SDM OR THE RADIO.

Clear the DTCs from all modules using the Tech 2 scan tool.
Remove the Tech 2® from the vehicle
Ensure the proper operation of the SDM by turning OFF the ignition and then turning ON the ignition. The air bag warning indicator should flash seven times and then go OFF.
Refer to Corporate Bulletin Number 99-09-41-001 for additional information regarding proper reprogramming of the new/replaced module.

Clearing codes from the other modules is part of the replacement and reprogramming procedure for the replaced module. The repair is not complete unless all codes have been cleared from all modules.

DO NOT SUBMIT CLAIMS FOR OTHER MODULE REPLACEMENTS OR REPROGRAMMING.



GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer".

Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely.

That's one message I wouldn't take lightly.
