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 monitors the circuits to the passenger belt pretensioner for faults. If the RCM detects an unexpected voltage on the passenger safety belt pretensioner circuits, it will store diagnostic trouble code (DTC) B1882 in memory and flash lamp fault code (LFC) 34 (or higher priority code if one exists) on the air bag warning indicator.

Fault Conditions
The RCM monitors for the following fault conditions:
- Circuit short to voltage

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