B2255-OCCUPANT RESTRAINT CONTROLLER ROLL OVER FEATURE DISABLE

Theory of Operation
When powered, the Occupant Restraint Controller (ORC) Module performs an internal self- test. The repair of this fault does not involve any external circuitry and centers on verifying the module is configured correctly for the vehicle's restraint system components.
- When Monitored:
The ORC checks the feature configuration at power- up during the initialization process, and continuously through the ignition cycle.

- Set Condition:
This Diagnostic Trouble Code (DTC) sets when the ORC detects the rollover feature has been disabled contrary to the correct vehicle configuration or has been disabled with the scan tool.





Always Perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Restraints System Pre-Diagnostic Procedure.
