Normal Operation

NOTE: There is currently no restraint system diagnostic tool for the safety belt buckle pretensioner under the seat connectors. When diagnosing the safety belt buckle pretensioners, it is necessary to disconnect the affected safety belt buckle pretensioner pigtail harness connector on the component and install a restraint system diagnostic tool.

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.
- 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 faulted pretensioner.
- a faulted RCM.
