B220B-00-OCCUPANT RESTRAINT CONTROLLER FIRING STORED ENERGY

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 condition does not involve any external circuitry and centers on verifying the integrity of the module's internal circuitry and software validity.

- When Monitored:
The ORC checks the status of firing stored energy circuit at power up during the initialization process, and continuously through the ignition cycle.

- Set Condition:
This Diagnostic Trouble Code (DTC) sets when a fault is detected internal to ORC firing stored energy circuit. Once set, this DTC is latched permanently and the ORC must be replaced.





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

Diagnostic Test
REPLACE OCCUPANT RESTRAINT CONTROLLER (ORC)

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.

When this code is set do not clear codes, view repair.

Repair

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