B2255-OCCUPANT RESTRAINT CONTROLLER ROLL OVER FEATURE DISABLE

For a complete wiring diagram REFER to DIAGRAMS/ELECTRICAL .

Theory of Operation


When powered, the Occupant Restraint Controller (ORC) 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 DTC sets when the ORC detects the roll over 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.


Diagnostic Test


1. CHECK ACTIVE DTC
NOTE: Ensure the battery is fully charged.

Turn the ignition on.
With the scan tool, perform ORC reset.
