Normal Operation
The safety belt pretensioners are activated by the RCM to remove excessive slack from the safety belt webbing when an impact exceeding preprogrammed limits is detected.

The restraints control module (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 diagnostic trouble code (DTC) B2292 in memory and flash, depending on the fault indicator, either lamp fault code (LFC) 33 or 34 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
- High resistance or circuit open
- Circuit short to voltage
- Circuit short to ground

Possible Causes
A safety belt pretensioner fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulted pretensioner.
- a faulted RCM.
