Occupant Restraint Controller

B223B - Vehicle Configuration Mismatch

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 centers on verifying ORC and totally integrated power module configuration.

• When Monitored: The ORC checks its feature configuration for side airbags present against the bus continuously 12 seconds after initialization.

• Set Condition: This DTC sets when the ORC detects a mismatch between the current and originally intended configuration of the module. Once set, this DTC is latched for the entire power cycle.






Always perform the Pre - Diagnostic Troubleshooting procedure before proceeding.

Test Step 1 - Determine Active or Stored DTC

• Ensure the battery is fully charged.

• Turn the ignition ON.

• Wait 12 seconds, then with the scan tool, read all active ORC DTCs.

Is the DTC active or stored?

ORC - active DTC

• Go to Test Step 2 => [ Test Step 2 - Check TIPM Side Airbags Present Configuration ]

ORC - Stored DTC

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

Test Step 2 - Check TIPM Side Airbags Present Configuration

• With the scan tool, check for side airbags configuration.

Does the vehicle configuration in the TIPM match the vehicle configuration in the ORC?

Yes

• Replace the ORC..

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


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 and serious or fatal injury.


to avoid serious or fatal injury, turn the ignition OFF, disconnect the battery and wait two minutes before proceeding.

No

• Configure the TIPM.

• The ORC reset function must be performed after the repair to force the module to retest for this DTC. Access the miscellaneous function menu from the ORC ECU overview screen on the scan tool to perform this operation.
