Diagnostic Procedure
- IDENTIFYING VEHICLE EQUIPMENT NOTE: Make sure the battery is fully charged.
- Turn the ignition on.
- With the scan tool, read ORC active DTCs.
Does the scan tool display active DTC: B1B94-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT HIGH?
Yes
- Go to step 2
No
- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- 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 for a complete list of diagnostic procedures.
No
- Go To 3
- With the scan tool, read Occupant Restraint Controller (ORC) DTCs.
- INSPECT DRIVER 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 in accordance with the Service Information.
- Perform the RESTRAINTS SYSTEM INTERMITTENT 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 the condition inspecting or testing for is present in the Seat Harness.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 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 5
No
- Reroute the driver seat harness as necessary.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- Verify that the driver seat harness is routed correctly.
- CHECK FOR DTC B1B94-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT HIGH WITH PASSENGER 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, and then with the scan tool, read ORC DTCs.
Does the scan tool display: B1B94-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT HIGH?
Yes
- Go To 6
No
- Replace the Passenger Seat Track Position Sensor in accordance with 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 connectors.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 at the Driver Seat Track Position Sensor connector cavity 1.
- Measure the voltage of the (R264) Passenger Seat Position Sensor Voltage circuit at the Driver Seat Track Position Sensor connector cavity 2.
Is the voltage above 0.2 of a volt on either circuit?
Yes
- Replace the Passenger Seat Harness in accordance with 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 the condition inspecting or testing for is present in the Seat Harness.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.No
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- Disconnect the ORC connectors.
- CHECK (R262) PASSENGER SEAT POSITION SENSOR DATA CIRCUIT FOR A SHORT TO (R264) 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 in accordance with 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 the condition inspecting or testing for is present in the Seat Harness.No
- Replace the ORC in accordance with the Service information.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
