B1BCF-ROLL OVER SENSOR

Theory of Operation

When powered, the Occupant Restraint Controller (ORC) performs an internal self test. The repair of this fault condition does not involve any external circuitry and centers on verifying the integrity of the module's internal memory.

- When Monitored:
The ORC checks the status and validity of the internal operating hardware and software at power up during the initialization process, and continuously through the ignition cycle.

- Set Condition:
This DTC will set if the module identifies an out of range Roll Over Sensor circuit.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Testing and Inspection.
REPLACE OCCUPANT RESTRAINT CONTROLLER

NOTE: When this DTC is set, the module self test has discovered an internal fault that cannot be repaired and the module must be replaced regardless of DTC status.

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.

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

When this code is set, view repair.
