ADC4-OCCUPANT RESTRAINT CONTROLLER INTERNAL FAULT

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 circuitry and software validity

- When Monitored:
With the ignition on.

- Set Condition:
The Occupant Restraint Controller (ORC) on board diagnostics continuously performs internal circuit tests. The ORC will set this DTC an out of range internal circuit identified.





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

Diagnostic Test

1. REPLACE THE ORC
NOTE: Ensure that the battery is fully charged.



Repair
