Normal Operation
The front air bags will deploy upon receiving a flow of current from the restraints control module (RCM).
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 a lamp fault code on the air bag indicator.
Fault Conditions
The RCM monitors for the following fault conditions:
- low resistance.
- high resistance or circuit open.
- circuit short to voltage.
- circuit short to ground.
Possible Causes
A driver air bag fault can be caused by:
- faulted wiring, terminals, or connectors.
- a faulty clockspring.
- a faulty driver air bag module.
- a faulted RCM.
A passenger air bag fault can be caused by:
- faulted wiring, terminals, or connectors.
- a faulty passenger air bag module.
- a faulted RCM.
