My airbag light flashes and stays on. I have a '99 vert. I recently installed a Halltech Stinger, and the light came on right after I started up. Is there any connection, like maybe the computer is confused about something? Is there anything to re-set? BTW I replaced my battery a few weeks ago with an Optima, but everything was OK after that.

No way the Halltech caused that problem..I hate when crap like that happens..because its like WTF??

That's exactly what I said.

When Power is first applied, there are several "power on" and "self tests" performed by various Modules. The Airbag indicator lite should flash 7 times, then go out. If not, it points to either the SDM (Sensor and Diagnostic Module) the airbags themselves, BCM or the connections between these components.
What Codes are being reported by the DIC?

What codes Codes tell all.

I checked the codes and all end in H (which I understand is in the past and OK now), except 1 that reads:

58-SDM B1001 H C

I can't find that code listed. What does this mean?

This is Right out of the Manual...Hope it helps!!

When the ignition key is first turned to the RUN position, the inflatable restraint sensing and diagnostic module (SDM) compares the restraints ID that is stored in the SDM to the restraints ID that is stored in the BCM. The restraints ID that is being compared contains the last four digits of the SDM part number.

Conditions for Setting the DTC

Ignition 1 voltage is within the normal operating voltage range.
The restraints ID that is stored in the SDM does not match the restraints ID that is stored in the BCM.

This test is only run once during power up initialization.

Action Taken When the DTC Sets

The SDM sets a DTC B1001.
The SDM commands ON the AIR BAG warning lamp via Class 2 serial data.
The SDM disables all deployments.
Conditions for Clearing the DTC
The restraints ID that is stored in the SDM matches the restraints ID that is stored in the BCM.

Diagnostic Aids

DTC B1001 is an indication that the restraints ID's stored in both the BCM and SDM do not match. If either the BCM and/or PCM were replaced, the replacement modules need to be reprogrammed for proper operation.

12stepvette,
Thanks for the info.

I did not have any work done on the BCM or PCM.
So, can I manually try to clear the code,
Then,
If the DTC repeats then I have a problem that needs repair.
If the DTC does not come back, that means the IDs actually match and then I'm OK?
