Occupant Restraint Controller (ORC)

9032-SEAT BELT BUCKLE CENTER SWITCH SHORT TO GROUND

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 Seat Belt Buckle Center Switch, the Occupant Restraint Controller (ORC) checks the switch input current ranges.

- Set Condition:
If the ORC detects that there a short to ground on the passenger seat belt buckle switch circuits.





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

1. VERIFY ACTIVE SEAT BELT BUCKLE CENTER SWITCH CIRCUIT LOW

3. Connect the Load Tool ORC 8443-28 Adapter to the ORC connectors.
4. Measure the resistance of the Seat Belt Buckle Center Switch Sense circuit between the Seat Belt Buckle Center Switch connector cavity 2 and ground.

Is the resistance below 10k Ohms on any of these circuits?

Yes

- Repair the Seat Belt Buckle Center Switch Sense circuit shorted to ground.
- Perform the RESTRAINTS SYSTEM VERIFICATION TESTVerification Tests

No

- Go To 3

3. VERIFY CIRCUITS SHORTED TOGETHER
1. Measure the resistance between the Seat Belt Buckle Center Switch Sense circuit cavity 2 and Ground circuit cavity 1 at the Seat Belt Buckle Center Switch connector.

Is the resistance less than 10K Ohms?

Yes

- Repair the Seat Belt Buckle Center Switch Sense circuit shorted to the Seat Belt Buckle Center Switch Ground circuit.
- Perform the RESTRAINTS SYSTEM VERIFICATION TESTVerification Tests.

No

- Go To 4

4. CHECK OPERATION OF THE SEAT BELT BUCKLE CENTER SWITCH
1. Replace the Seat Belt Buckle Center 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 and 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: 9032-SEAT BELT BUCKLE CENTER SWITCH SHORT TO GROUND 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.
