    2. Connect the SRS Load Tool Adapter 8443-25 to the ORC harness connectors.
    3. Keep the in-line under-seat connector and the Driver Active Headrest connector in the driver seat back connected.
      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.
    4. Measure the voltage of the (R676) Active Head Restraint 1st Row Driver Signal circuit at the appropriate terminal of the SRS Load Tool Adaptor 8443-25 and ground.

      Is there voltage present?

      Yes 

      • Go to step  4

      No 

      • Go to step  5
  4. CHECK THE (R676) ACTIVE HEAD RESTRAINT 1ST ROW DRIVER SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE BETWEEN THE ORC AND THE IN-LINE UNDER-SEAT CONNECTOR (BODY 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.
    NOTE: Inspect for damaged terminals at the in-line under-seat jumper harness connector.
    1. Disconnect the in-line under-seat harness 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. Measure for voltage between ground and the (R676) Active Head Restraint 1st Row Driver Signal circuit at the appropriate terminal of the SRS Load Tool Adaptor 8443-25.

      Is there voltage present?

      Yes 

      No 

      • Go to step  5
  5. CHECK THE (R676) ACTIVE HEAD RESTRAINT 1ST ROW DRIVER SIGNAL CIRCUIT FOR SHORT TO VOLTAGE IN THE SEATBACK HARNESS

    1. Connect the in-line under seat harness connector.
    2. Access the Driver Active Headrest connector located in the driver seat back jumper harness.
    3. Disconnect the Driver Active Headrest harness 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.
    4. Measure the voltage between ground and the (R676) Active Head Restraint 1st Row Driver Signal circuit at the appropriate terminal of the SRS Load Tool Adaptor 8443-25.

      Is there voltage present?

      Yes 

      No 

      • Go to step  6
  6. CHECK THE OPERATION OF THE DRIVER ACTIVE HEAD RESTRAINT 
    1. Replace the Driver Active Head Restraint.
