Occupant Restraint Controller (ORC)

B223B-VEHICLE CONFIGURATION MISMATCH

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 centers on verifying ORC and Totally Integrated Power Module (TIPM) configuration.

- When Monitored:
The ORC checks its feature configuration for side airbags present against the BUS continuously 12 seconds after initialization.

- Set Condition:
This DTC sets when the ORC detects a mismatch between the current and originally intended configuration of the module. Once set, this DTC is latched for the entire power cycle.





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

1. DETERMINE ACTIVE OR STORED DTC

NOTE: Make sure the battery is fully charged.

1. Turn the ignition on.
2. Wait 12 seconds, then with the scan tool, read all active ORC DTCs.

Is the DTC active or stored?

ORC - ACTIVE DTC

- Go To 2

ORC - STORED DTC

- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Restraints System Intermittent Condition Test.

2. CHECK TIPM SIDE AIRBAGS PRESENT CONFIGURATION
1. With the scan tool, check for Side Airbags configuration.

Does the Vehicle Configuration in the TIPM match the Vehicle Configuration in the 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 and serious or fatal injury.

- WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

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

No

- Configure the TIPM.
- NOTE: The ORC Reset Function must be performed after the repair to force the module to retest for this DTC. Access the Miscellaneous Function or Diagnostic Procedures menu from the ORC ECU Overview screen on the scan tool to perform this operation.
