9012-DRIVER SEAT BELT SWITCH SHORT TO GROUND





For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
While the ignition on and the Occupant Classification Module (ORC) configured for a Driver Seat Belt 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.

Diagnostic Test

1. VERIFY ACTIVE DRIVER SEAT BELT SWITCH CIRCUIT LOW

NOTE: Ensure the battery is fully charged.

Turn the ignition on.
With the scan tool, read ORC DTC.
Does the scan tool display active: 9012-DRIVER SEAT BELT SWITCH SHORT TO GROUND?

Yes

- Go To 2

No

- Perform *RESTRAINTS SYSTEM INTERMITTENT TEST.

2. VERIFY DRIVER SEAT BELT SWITCH CIRCUITS FOR A SHORT TO GROUND




WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Disconnect the Driver Seat Belt Switch connector.
Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.

Connect the Load Tool ORC 8443-28 Adapter to the ORC connectors.
Measure the resistance of the Driver Seat Belt Switch Sense circuit between the Driver Seat Belt Switch connector cavity 2 and ground.
Is the resistance below 10k ohms on any of these circuits?

Yes

- Repair the Driver Seat Belt Switch Sense circuit shorted to ground.
- Perform *RESTRAINTS SYSTEM VERIFICATION TEST. Verification Tests

No

- Go To 3

3. VERIFY CIRCUITS SHORTED TOGETHER




Measure the resistance between the Driver Seat Belt Switch Sense circuit cavity 2 and Ground circuit cavity 1 at the Driver Seat Belt Switch connector.
Is the resistance less than 10K ohms?

Yes

- Repair the Driver Seat Belt Switch Sense circuit shorted to the Driver Seat Belt Switch Ground circuit.
- Perform *RESTRAINTS SYSTEM VERIFICATION TEST. Verification Tests

No

- Go To 4

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

WARNING: To avoid serious or fatal injury, turn the ignition ON, then reconnect the battery.

Connect the scan tool to the Data Link Connector - use the most current software available.
Use the scan tool and erase the stored codes in all airbag system modules.
Turn the Ignition Off, and wait 15 seconds before turning the Ignition On.
Wait one minute, and read active codes and if there are none present read the stored codes.
Did the active: 9012-DRIVER SEAT BELT SWITCH SHORT TO GROUND DTC return?

Yes

WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

WARNING: If the airbag control module is dropped at any time, it must be replaced. Failure to take the proper precautions could result in accidental airbag deployment and serious or fatal injury.

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

No

- Repair is complete.
