B2207-OCCUPANT RESTRAINT CONTROLLER INTERNAL 1

For a complete wiring diagram REFER to DIAGRAMS/ELECTRICAL .

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 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 sets when a fault is detected internal to ORC hardware and/or software. Once set, this DTC is latched for the entire power cycle. If the same failure is detected in two consecutive power cycles, this DTC is latched active indefinitely.







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


Diagnostic Test


1. 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.

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 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.
- Perform *RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.
