BM12-BM14:

Normal Operation
The restraints control module (RCM) checks the driver side impact sensor circuits for faults. If the RCM detects one of the following faults on the driver side impact sensor circuits, it will store diagnostic trouble code (DTC) U2017 in memory and illuminate 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 side impact sensor communication fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulty driver side impact sensor.
- incorrect sensor mounting.
- a faulted RCM.
