Occupant Restraint Controller (ORC)

9023-PASSENGER SEAT BELT SWITCH CIRCUIT OPEN

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

- When Monitored:
While the ignition on and the Occupant Classification Module (ORC) configured for a Passenger Seat Belt Switch, the Occupant Restraint Controller (ORC) module checks the switch input current ranges.

- Set Condition:
The Diagnostic Trouble Code (DTC) will be set active if the ORC detects an open or high resistance on the passenger seat belt switch circuits.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Restraints System Pre-Diagnostic Procedure

1. VERIFY ACTIVE 9023-PASSENGER SEAT BELT SWITCH CIRCUIT OPEN DTC

NOTE: Make sure the battery is fully charged.

1. Turn the ignition on.
2. Using the scan tool, read ORC DTCs.

Does the scan tool display active: 9023-PASSENGER SEAT BELT SWITCH CIRCUIT OPEN?

Yes

- Go To 2

No

- Verification Tests.

No

- Go To 3

3. VERIFY PASSENGER SEAT BELT SWITCH CIRCUITS OPEN
1. Measure the resistance of the Ground circuit between the Passenger Seat Belt Switch connector and ground.

Is the resistance greater than 1 Ohm on either circuit?

Yes

- Repair the open Ground circuit.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST.Verification Tests.

No

- Go To 4

4. CHECK OPERATION OF THE PASSENGER SEAT BELT SWITCH
1. Replace the Passenger Seat Belt Switch.
2. Reconnect the vehicle body harness to the switch.
3. Remove any special tools or jumper wires and reconnect all previously disconnected components - except the Battery.

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

4. Connect the scan tool to the Data Link Connector - use the most current software available.
5. Use the scan tool and erase the stored codes in all airbag system modules.
6. Turn the Ignition Off, and wait 1five seconds before turning the Ignition On.
7. Wait one minute, and read active codes and if there are none present read the stored codes.

Did the active: 9023-PASSENGER SEAT BELT SWITCH CIRCUIT OPEN DTC return?

Yes

- 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.

- 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.

- Replace the Occupant Restraint Controller.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST.Verification Tests.

No

- Repair is complete.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST.Verification Tests.
