Diagnostic Test

  1. IDENTIFYING VEHICLE EQUIPMENT 
    NOTE: Make sure the battery is fully charged.
    1. Turn the ignition on.
    2. With the scan tool, read ORC active DTCs.

      Does the scan tool display active DTC: B1B8E-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT HIGH?

      Yes 

      • Go to step  2

      No 

  2. CHECK FOR ACTIVE INTERNAL FAULTS, IGNITION FAULTS, AND BATTERY FAULTS IN THE OCCUPANT RESTRAINT CONTROLLER (ORC) 
    1. 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 

      No 

      • Go to step  3
  3. 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.
    1. 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 

      No 

      • Go to step  4
  4. VERIFY THAT DRIVER SEAT HARNESS IS ROUTED CORRECTLY 
    1. Verify that the driver seat harness is routed correctly.

      Is the Driver Seat Harness routed correctly?

      Yes 

      • Go to step  5

      No 

  5. CHECK FOR DTC B1B8E-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT HIGH 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.
    1. 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.
    2. Wait two minutes, and then with the scan tool, read ORC DTCs.

      Does the scan tool display: B1B8E-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT HIGH?

      Yes 

      • Go to step  6

      No 

  6. CHECK (Z261) DRIVE SEAT POSITION SENSOR GROUND CIRCUIT AND (R263) DRIVE SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR A SHORT TO VOLTAGE

    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.
    1. 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.
    2. Measure the voltage of the (Z261) Driver Seat Position Sensor Ground circuit at the Driver Seat Track Position Sensor connector cavity 1.
    3. Measure the voltage of the (R263) Driver 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 

        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 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
      • 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 .

      No 

      • Go to step  7
  7. CHECK (Z261) DRIVER SEAT POSITION SENSOR GROUND CIRCUIT FOR A SHORT TO (R263) 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.
    1. Measure the resistance between the (Z261) Driver Seat Position Sensor Ground circuit cavity 1 and the (R263) Driver Seat Position Sensor Voltage circuit cavity 2 in the Driver Seat Track Position Sensor connector.

      Is the resistance below 10k Ohms?

      Yes 

      No
