Normal Operation
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 (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 safety belt pretensioner status fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulty pretensioner.
- RCM is faulted.
