Normal Operation
The restraints control module (RCM) checks all of the front air bag circuits for faults. If the RCM detects one of the following faults on any of the front air bag circuits, it will store diagnostic trouble code (DTC) B2293 in memory, and depending on the fault, flash either lamp fault code (LFC) 19 or 21 depending on the fault (or higher priority code if one exists) on the air bag indicator.

Fault Conditions
The RCM monitors for the following fault conditions:
- low resistance.
- circuit open.
- circuit short to voltage.
- circuit short to ground.

Possible Causes
A driver air bag status fault can be caused by:
- damaged wiring, terminals, or connectors.
- driver air bag sub-harness.
- a faulty clockspring.
- a faulty driver air bag module.
- a faulted RCM.

A passenger air bag status fault can be caused by:
- damaged wiring, terminals, or connectors
- a faulty passenger air bag module.
- a faulted RCM.
