Lamp Fault Codes (LFC)
The lamp fault codes (LFCs) indicate the specific flagged faults associated with diagnostic trouble code (DTC) B2292:
NOTE: The secondary warning chime will be activated along with the primary warning indicator when a fault is detected.
Normal Operation
The safety belt pretensioners are activated by the restraints control module (RCM) to remove excessive slack from the safety belt webbing when an impact exceeding preprogrammed limits is detected.
The RCM checks all of the safety belt pretensioners for faults. If the RCM detects one of the following faults on any of the safety belt pretensioner circuits, it will store DTC B2292 in memory and, depending on the fault, flash a LFC on the air bag indicator. The secondary air bag warning chime will also be activated.
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 safety belt pretensioner fault can be caused by:
- wiring, terminals or connectors.
- a faulted pretensioner.
- a faulted RCM.
