Occupant Restraint Controller (ORC)

B223B-VEHICLE CONFIGURATION MISMATCH

For a complete wiring diagram refer to the Wiring Information. Electrical Diagrams

- When Monitored:
The Occupant Restraint Controller (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.





1. DETERMINE ACTIVE OR STORED DTC

NOTE: Ensure the battery is fully charged.

1. Turn the ignition on.
2. Wait 12 seconds, with the scan tool, read all active ORC DTCs.

Is the DTC active or stored?

ORC - ACTIVE DTC

- Go To 2

ORC - STORED DTC

- Go To 3

2. CHECK THE TIPM SIDE AIRBAGS PRESENT CONFIGURATION
1. With the scan tool, check for Side Airbags configuration.

Does the Vehicle Configuration in the TIPM match the Vehicle Configuration in the ORC?

Yes

- WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. 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.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

No

- Configure the Totally Integrated Control Module (TIPM). Body Verification Test.

3. STORED ORC DTC
1. With the scan tool, record and erase all DTCs from all Airbag System Modules.
2. If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.

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.

3. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
4. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
5. The following additional checks may assist you in identifying a possible intermittent problem.
6. Reconnect any disconnected components and harness connector.

WARNING: Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

7. With the scan tool monitor active codes as you work through the following steps.

WARNING: To avoid serious or fatal injury, maintain a safe distance from all airbags while performing the following steps.

8. Wiggle the wiring harness and connectors of the related airbag circuit or component.
9. If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
10. If only stored codes return continue the test until the problem area has been isolated.
11. In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.

Are any ACTIVE DTCs present?

Yes

- Select the appropriate diagnostic procedure. Testing and Inspection.

No

- No problem found at this time. Erase all codes before returning vehicle to customer.
