Normal Operation
The restraints control module (RCM) checks the passenger side impact sensor circuits for faults. If the RCM detects one of the faults on the passenger side impact sensor circuits, it will store diagnostic trouble code (DTC) U2018 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 passenger side impact sensor communication fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulty passenger side impact sensor.
- incorrect sensor mounting.
- a faulted RCM.
