Diagnostic Test
- CHECK FOR ACTIVE INTERNAL FAULTS, IGNITION FAULTS, AND BATTERY FAULTS IN THE OCCUPANT RESTRAINT CONTROLLER (ORC)
- With the scan tool, read Occupant Restraint Controller (ORC) DTCs.
Does the scan tool display any active DTCs relating to internal faults, ignition faults, or battery faults?
Yes
- Diagnose and repair the DTCs. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Diagnosis and Testing .
No
- Go to step 2
- With the scan tool, read Occupant Restraint Controller (ORC) DTCs.
- VERIFY THAT DTC B1B8F-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT OPEN IS ACTIVE
Does the scan tool display active: B1B8F-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT OPEN?
Yes
- Go to step 3
No
- Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- INSPECT DRIVER SEAT HARNESS WIRES AND CONNECTORS 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.
- Using the SYSTEM WIRING DIAGRAMS
as a guide, inspect the Driver Seat Harness wiring and connectors. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
Are any of these conditions present?
Yes
- Replace the Driver Seat Harness in accordance with the Service Information.
- Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
NOTE: Do not attempt to repair the Seat Harness. Replace the Seat Harness if any of these conditions existNo
- Go to step 4
- Using the SYSTEM WIRING DIAGRAMS
as a guide, inspect the Driver Seat Harness wiring and connectors. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
- VERIFY THAT DRIVER SEAT HARNESS IS ROUTED CORRECTLY
- Verify that the Driver Seat Harness is routed correctly.
Is the Driver Seat Harness routed correctly?
Yes
- Go to step 5
No
- Reroute the Driver Seat Harness as necessary.
- Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- Verify that the Driver Seat Harness is routed correctly.
- CHECK FOR DTC B1B8F-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT OPEN WITH DRIVER SEAT TRACK POSITION SENSOR DISCONNECTED 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.
- Disconnect the Driver Seat Track Position Sensor 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.
- Wait two minutes, and then with the scan tool, read ORC DTCs.
Does the scan tool display: B1B8F-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT OPEN?
Yes
- Go to step 6
No
- Replace the Driver Seat Track Position Sensor in accordance with the service information.
- Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
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.
- Disconnect the Driver Seat Track Position Sensor connector.

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.- Disconnect the ORC C1 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.
- Measure the voltage of the (Z261) Driver Seat Position Sensor Ground circuit between the Driver Seat Track Position Sensor connector and ground.
- Measure the voltage of the (R263) Driver Seat Position Sensor Voltage circuit between the Driver Seat Track Position Sensor connector and ground.
Is the voltage above 0.2 of a volt on either circuit?
Yes
- Replace the Driver Seat Harness in accordance with the Service Information.
- Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
NOTE: Do not attempt to repair the Seat Harness. Replace the Seat Harness if any of these conditions existWARNING: 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.No
- Go to step 7
- Disconnect the ORC C1 connector.
- CHECK (Z261) DRIVER SEAT POSITION SENSOR GROUND CIRCUIT FOR A SHORT TO (R263) DRIVER SEAT POSITION SENSOR VOLTAGE CIRCUIT Fig 2: Checking Driver Seat Position Sensor Ground Circuit For A Short To Driver Seat Position Sensor Voltage Circuit

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.- Measure the resistance between the (Z261) Driver Seat Position Sensor Ground circuit and the (R263) Driver Seat Position Sensor Voltage circuit in the Driver Seat Track Position Sensor connector.
Is the resistance below 10k Ohms?
Yes
- Replace the Driver Seat Harness in accordance with the service information.
- Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
NOTE: Do not attempt to repair the Seat Harness. Replace the Seat Harness if any of these conditions existNo
- Replace the ORC in accordance with the Service information.
- Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- Measure the resistance between the (Z261) Driver Seat Position Sensor Ground circuit and the (R263) Driver Seat Position Sensor Voltage circuit in the Driver Seat Track Position Sensor connector.
