The airbag light is going on intermittentaly due to the left driver door sensor. I have tried changing the sensor, the steering clock spring, and checking the door wiring harness and I don't see any issue. However the light still comes on intermittently and usually just shutting down and restarting the car will make it go away. I also get codes for a ride height sensor and loss of communication with instrument cluster. The battery is new and I have tried clearing the code many times but it still comes back. Are there any ideas on how to find the issue?

 

So there is a code for left Driver door SRS sensor?

 

yes I get code B0091 permanent, bus signal/message failure - invalid serial data received

 

And you have referenced that code to some explanation that its the door?

 

Yeah I'm confused too. You sure the problem isn't with the seat cushion pressure sensor (NAS only) or seat cushion pressure pad (NAS only) - passenger seat?
