I'm not sure what code numbers you have but I have learned there is a problem with the wiring harness under the front seats and that has been a fix by replacing it.
"ASSIST A/B MODULE [SHORT] [B1068] or [B1073] Front passenger air bag module circuits [wires] are shorted to each other.
ASSIST A/B MODULE [OPEN] [B1065] or [B1070] Front passenger air bag module circuit is open.
1. Visually check the wiring harness connection. 2.Replace the harness if it has visible damage. 3.Replace front passenger air bag module. 4.Replace the air bag diagnosis sensor unit. 5.Replace the related harness."
IF it has been deployed, I also learned this:
"HARNESS CONNECTOR DAMAGE IS COMMON AFTER DEPLOYMENT. In particular, the push in locking device (usually black) gets damaged if not released before removing the connector from the bag. Driver side common melting problems requiring clockspring replacement. The locking device also serves to release the airbag shorting bars so, if they are damaged or missing, you will get a "short circuit" code. Try with 2ohm - 1/4 watt resistors in the harness side and clear codes."
For diagnosis, this is where we start:
Turn the ignition key on and foolow the air bag light for the following patterns and get back to me:
