I changed the driver seat and the airbag light came on. The SES light on the left side is also on. I put the original seat back and the lights are still on. I can clear the airbag code but comes right back. The ses light will not clear because it claims there are no codes present. Any help is appreciated. Thanks , Ed

B1001 is a GM body control module (BCM) DTC error code meaning Option Configuration error. When it sets it will cause an airbag fault light but it does not mean the problem is with the SIR Airbag system or the SDM module. Actual airbag system fault codes start at B1015 and higher.

Was the seat replaced electric or manual? Have you checked all connectors and wiring underneath land to the seat belt switch? Is the seat belt warning working?

The light at the left hand side of the dash is the Service Vehicle Soon light and relates to the problem but a regular scanner will not reset it. Also, to reset the fault has to be corrected. The only other way I know of to get it reset is to take it to a GM dealer.

the seat is electric , I checked all connections and I used the original seat belt(I assume the seat belt warning is working, I have no relted lights or codes). THanks

I recall many of the electrical/electronic components tie into a serial bus for communications with the BCM and PCM. Something is missing or the system needs reconfiguration. Whatever your problem is it is related to changing out the electric seat. You may have to take it to a GM dealer with the replacement seat installed and let them do the job.

The only thing I can suggest is to disconnect the battery negative cable overnight. Some body and chassis codes seem to clear when that is done. Be sure to have your radio Theftlock codes (if active) before disconnecting the battery. Also, if you have a digital climate control system make sure it is in the off position.
