B1BD0 - Roll Over Internal

For a complete wiring diagram, refer to.

Theory of Operation

When powered, the occupant restraint controller 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.

• Ensure the battery is fully charged.

• Turn the ignition ON.

• With the scan tool, read ORC DTCs.

Is the DTC active or stored?

ORC - active DTC

• Replace the ORC.

• Perform the Restraints System Intermittent Test. Refer to => Non - DTC Based Diagnostics. ORC Restraints System Intermittent Test

• Ensure the part number of the replacement module is the correct part number for the vehicle.


If the occupant restraint controller 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.


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.

ORC - Stored DTC

• Perform the Restraints System Intermittent Test. Refer to => Non - DTC Based Diagnostics. ORC Restraints System Intermittent Test
