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, depending on the fault, flash a lamp fault code (LFC) 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:
- faulted wiring, terminals, or connectors.
- a faulted pretensioner.
- a faulted RCM.
