Normal Operation
The restraints control module (RCM) monitors safety belt buckle pretensioner circuits for faults. The RCM will set a diagnostic trouble code (DTC) if a short to battery or short to ground fault is detected.The RCM will also set a DTC if the loop resistance is less than 0.9 ohm or greater than 5.0 ohms. The normal expected resistance range is 1.31 to 4.29 ohms. If a loop resistance is between 0.9 and 1.31 or between 4.29 and 5.0 ohms, there exists a strong potential for an intermittent fault.If the RCM detects one of the following faults on any of the safety belt buckle pretensioner circuits, it will store diagnostic trouble code (DTC) B2292 in memory and illuminate the air bag warning indicator.

Fault Condition
The RCM monitors for the following fault conditions:
- Loop resistance less than 0.9 ohm (Low resistance)
- Loop resistance greater than 5.0 ohms (Circuit open)
- Circuit short to voltage
- Circuit short to ground

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