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: B1B8D-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT LOW?

      Yes 

      • Go To  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  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 

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

      Is the resistance below 10k Ohms 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.

      No 

      • Go To  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 SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) to the ORC C1 connector.
    3. Measure the resistance of the (R261) Driver Seat Position Sensor Data circuit between the SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) appropriate cavity and the Driver Seat Track Position Sensor connector cavity 1.
    4. Measure the resistance of the (R263) Driver Seat Position Sensor Voltage circuit between the SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) appropriate cavity and the Driver Seat Track Position Sensor connector cavity 2.

      Is the resistance of either circuit above 5.0 Ohms?

      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.

      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 take the proper precautions can result in accidental airbag deployment. Failure to follow these instructions may result in possible serious or fatal injury.
