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 either lamp fault code (LFC) 42, 43, or 44 depending on the fault (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 battery.
- Circuit short to ground.
Possible Causes
A front impact severity sensor status fault can be caused by:
- Wiring, terminals, or connectors.
- A faulty front impact severity sensor.
- Incorrect front impact severity sensor mounting.
- A faulty RCM.
A side impact sensor status fault can be caused by:
- Wiring, terminals, or connectors.
- A faulty side impact sensor.
- Incorrect side impact sensor mounting.
- A faulty RCM.
