Diagnostic Test

  1. CHECK FOR ACTIVE INTERNAL FAULTS, IGNITION FAULTS, AND BATTERY FAULTS IN THE OCCUPANT RESTRAINT CONTROLLER (ORC) 
    NOTE: Ensure the battery is fully charged
    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  2
  2. VERIFY THAT DTC B1B8D-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT LOW IS ACTIVE 

    Does the scan tool display active: B1B8D-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT LOW?

    Yes 

    • Go to step  3

    No 

  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 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 

      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 (R261) DRIVER SEAT POSITION SENSOR DATA CIRCUIT AND (R263) DRIVER SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR A SHORT TO GROUND

    1. Measure the resistance between ground and the (R261) Driver Seat Position Sensor Data circuit.
    2. Measure the resistance between ground and the (R263) Driver Seat Position Sensor Voltage circuit.

      Is the resistance below 10K Ohms on either circuit?

      Yes 

      No 

      • Go to step  6
  6. CHECK (R261) DRIVER SEAT POSITION SENSOR DATA CIRCUIT AND (R263) DRIVER SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR AN OPEN

    1. Disconnect the ORC connectors.
    2. Connect the Load Tool ORC Adaptor 8443-24 to the ORC C1 harness connector.
    3. Measure the resistance of the (R261) Driver Seat Position Sensor Data circuit between the ORC-C1 connector and the Driver Seat Track Position Sensor connector.
    4. Measure the resistance of the (R263) Driver Seat Position Sensor Voltage circuit between the ORC-C1 connector and the Driver Seat Track Position Sensor connector.

      Is the resistance of either circuit above 5.0 ohms?

      Yes 

      No 

        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.
        WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.
      • Replace the Occupant Restraint Controller (ORC) in accordance with the service information.
      • Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
