Diagnostic Procedure
- CHECK FOR ACTIVE INTERNAL FAULTS, IGNITION FAULTS, AND BATTERY FAULTS IN THE OCCUPANT RESTRAINT CONTROLLER (ORC)
- Using a 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 for a complete list diagnostic procedures.
No
- Go to step 2
- Using a scan tool, read Occupant Restraint Controller (ORC) DTCs.
- VERIFY THAT DTC B1B95-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT OPEN IS ACTIVE
Does the scan tool display active B1B95-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT OPEN?
Yes
- Go to step 3
No
- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- INSPECT PASSENGER SEAT HARNESS WIRES AND CONNECTORS WARNING: Turn the ignition off, disconnect the battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
- Using the wiring diagram/schematic 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 passenger seat harness according to the Service Information.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
NOTE: Do not attempt to repair the driver seat harness. Replace the driver seat harness if any of these conditions exist.No
- Go to step 4
- Using the wiring diagram/schematic 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 THE PASSENGER SEAT HARNESS IS ROUTED CORRECTLY
- Verify the driver seat harness is routed correctly.
Is the driver seat harness routed correctly?
Yes
- Go to step 5
No
- Reroute the passenger seat harness as necessary.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- Verify the driver seat harness is routed correctly.
- CHECK FOR DTC B1B95-PASSENGER 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 Passenger Seat Track Position Sensor connector.WARNING: Turn the ignition on, then reconnect the battery and wait two minutes to proceed. Failure to follow these instructions may result in possible serious or fatal injury.
- Wait two minutes, then using a scan tool, read ORC DTCs.
Does the scan tool display: B1B95-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT OPEN?
Yes
- Go to step 6
No
- Replace the passenger seat track position sensor according to the Service Information.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
WARNING: Turn the ignition off, disconnect the battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
- Disconnect the Passenger Seat Track Position Sensor connector.

WARNING: Turn the ignition off, disconnect the 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 (R262) Passenger Seat Position Sensor Data circuit cavity 1 between the passenger seat track position sensor connector and ground.
- Measure the voltage of the (R264) Driver Seat Position Sensor Voltage circuit cavity 2 between the passenger seat track position sensor connector and ground.
Is the voltage above 0.2 of a volt for either circuit?
Yes
- Replace the driver seat harness according to the Service Information.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
NOTE: Do not attempt to repair the driver seat harness. Replace the driver seat harness if any of these conditions exist.WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the 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 (R262) PASSENGER SEAT POSITION SENSOR DATA CIRCUIT FOR A SHORT TO (R264) PASSENGER SEAT POSITION SENSOR VOLTAGE CIRCUIT Fig 2: Checking Passenger Seat Position Sensor Data Circuit For A Short To Passenger Seat Position Sensor Voltage Circuit

WARNING: Turn the ignition off, disconnect the 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 (R262) Passenger Seat Position Sensor Data circuit cavity 1 and the (R264) Passenger Seat Position Sensor Voltage circuit cavity 2 in the Passenger Seat Track Position Sensor connector.
Is the resistance below 10K Ohms?
Yes
- Replace the passenger seat harness according to the Service Information.
- Perform the RESTRAINTS SYSTEM 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 exist.No
- Replace the ORC according to the Service Information.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- Measure the resistance between the (R262) Passenger Seat Position Sensor Data circuit cavity 1 and the (R264) Passenger Seat Position Sensor Voltage circuit cavity 2 in the Passenger Seat Track Position Sensor connector.
