B2255-OCCUPANT RESTRAINT CONTROLLER ROLL OVER FEATURE DISABLE

For a complete wiring diagram, refer to the Wiring Information.

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.

1. CHECK ORC CONFIGURATION

NOTE: Ensure the battery is fully charged.

1. Turn the ignition on.
2. Perform ORC module reset. Access the Miscellaneous Function menu from the ORC ECU Overview screen on the scan tool to perform this operation.
3. With the scan tool, check ORC configuration.
4. With the scan tool, verify Roll Over configuration setting is enabled in ORC.

Is the Roll Over feature enabled in ORC?

Yes

- WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment. Failure to follow these instructions may result in possible serious or fatal injury.

- WARNING: Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

- Replace the ORC. Occupant Restraint Controller - Removal.
- Perform RESTRAINTS SYSTEM VERIFICATION TESTRestraints System Verification Test.

No

- Go To 2

2. ENABLE ROLL OVER FEATURE
1. With the scan tool, enable Roll Over configuration setting in ORC.
2. With the scan tool, perform ORC reset.
3. With the scan tool, read all active ORC DTCs.

Is DTC B2255-OCCUPANT RESTRAINT CONTROLLER ROLL OVER FEATURE DISABLE still active?

Yes

- WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment. Failure to follow these instructions may result in possible serious or fatal injury.
