B0099-96-ROLL OVER SENSOR - COMPONENT INTERNAL FAILURE

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 roll over sensor.

- When Monitored:
The ORC checks the status of the internal roll over sensor continuously through the ignition cycle.

- Set Condition:
This DTC sets when the ORC detects corruption in the data and circuitry related to the internal roll over sensor. Once set, this DTC is latched for the entire ignition cycle. If the failure is detected in two consecutive power cycles, the DTC is set indefinitely.





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

NOTE: Make sure the battery is fully charged.

1. Turn the ignition on.
2. With the scan tool, read ORC DTCs.

Is the DTC active or stored?

ORC - ACTIVE DTC

- NOTE: Make sure the part number of the replacement module is the correct part number for the vehicle.
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. Occupant Restraint Controller - Removal.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

ORC - STORED DTC

- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Restraints System Intermittent Condition Test.
