Occupant Restraint Controller
B222A - Vehicle LIN 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 the ORC and totally integrated power module configuration.
• When Monitored: The ORC checks its feature configuration for a stored vehicle LIN and country code continuously 12 seconds after initialization.
• Set Condition: This DTC sets when the ORC detects a mismatch between the vehicle configuration and the ORC configuration.
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 Country Code and Vehicle LIN ]
ORC - Stored DTC
• Perform Restraints System Intermittent Test. Refer to => Non-DTC Based Diagnostics. ORC Restraints System Intermittent Test
Test Step 2 - Check TIPM Country Code and Vehicle LIN
• With the scan tool, check for the correct Country Code, Vehicle LIN, and Body Style.
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.
