Normal Operation
The restraints control module (RCM) checks all of the impact sensor circuits for faults. If the RCM detects one of the following faults on any of the impact sensor circuits, it will store diagnostic trouble code (DTC) B2296 in memory and flash, depending on the fault, either lamp fault code (LFC) 42, 43, 44, 45 or 46 (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 impact sensor status fault can be caused by:
- damaged wiring, terminals, or connectors.
- a faulty impact sensor.
- incorrect sensor mounting.
- faulted RCM.
