Normal Operation
The restraints control module (RCM) checks the driver side impact sensor circuits for faults. If the RCM detects a short to ground or voltage on the driver side impact sensor circuits, it will store diagnostic trouble code (DTC) B104E in memory and illuminate the air bag indicator.

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

Possible Causes
A driver side impact sensor short to ground or voltage fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulted RCM.
