Lamp Fault Codes (LFCs)







The lamp fault codes (LFCs) indicate the specific flagged faults associated with diagnostic trouble code (DTC) B2296:

Normal Operation
The impact sensor(s) provide data to the restraints control module (RCM) for use in calculating impact severity. This is accomplished using various electrical and electro-mechanical sensor(s) throughout the vehicle.

The 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 DTC B2296 in memory and, depending on the fault, flash a LFC on the air bag indicator.

Fault Conditions
The RCM monitors for the following fault conditions:
- Low resistance
- High resistance or circuit open
- Circuit short to voltage
- Circuit short to ground

Possible Causes
A impact sensor fault can be caused by:
- wiring, terminals or connectors.
- a faulted impact sensor.
- incorrect sensor mounting.
- a faulted RCM.
