Occupant Restraint Controller (ORC)

B222A-VEHICLE LINE 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 the ORC and Totally Integrated Power Module (TIPM) configuration.

- When Monitored:
The ORC checks its feature configuration for a stored Vehicle Line and Country Code continuously 12 seconds after initialization.

- Set Condition:
This DTC sets when the ORC detects a mismatch between the Vehicle Configuration and the ORC configuration.
