B1BD0






B1BD0-ROLL OVER INTERNAL

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: The airbag warning lamp in the Cab Compartment Node/CCN (Instrument Cluster) sets.
