    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. Access the Passenger Active Head Rest harness connector located in the passenger seatback jumper harness.
    2. Disconnect the Passenger Active Headrest harness connectors.
      NOTE:

      Check the connectors - Clean and repair as necessary.

      NOTE:

      Please use the(special tool #10253, Tester, AHR Load) in testing the present status of the AHR signal circuit.

    3. Connect the(special tool #10253, Tester, AHR Load) to the passenger AHR seatback jumper harness connector going into the seatback and under the seat.
    4. If equipped with the standard key ignition, use this ignition on warning.
      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.

    5. If equipped with the keyless ignition, use this ignition on warning.
      WARNING:

      Disconnect the 12-volt battery wait two minutes before proceeding, remove the ORC fuses, connect the 12-volt battery, wait two minutes before proceeding. Cycle the ignition to the On position, then reconnect the ORC fuses. Wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

    6. With the scan tool, read the active ORC DTCs.

      Does the scan tool display: B1C17-13-PASSENGER-ACTIVE-HEADREST-CONTROL-CIRCUIT-OPEN?

      Yes 

      • Go To  3

      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.

      • Replace the Passenger Active Head Rest in accordance with the Service Information. Refer to HEADREST, FRONT, REMOVAL .
  3. CHECK THE (R677) ACTIVE HEAD RESTRAINT 1ST ROW PASSENGER SIGNAL CIRCUIT FOR A SHORT TO GROUND 
    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 ground and the (R677) Active Head Restraint 1st Row Passenger Signal circuit at the appropriate terminal of the 8443-55 tool.

      Is the resistance below 5 Ohms?

      Yes 

      • Repair the (R677) Active Head Restraint 1st Row Passenger Signal circuit for a short to ground.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

  4. CHECK THE (R677) ACTIVE HEAD RESTRAINT 1ST ROW PASSENGER SIGNAL CIRCUIT FOR AN OPEN OR HIGH RESISTANCE 
    1. Measure the resistance of the (R677) Active Head Restraints 1st Row Passenger Signal circuit between the Active Head Restraint 1st Row Passenger harness connector and the appropriate terminal of the 8443-55 tool.

      Is the resistance below 1 Ohm?

      Yes 

      • Go To  5

      No 

      • Repair the (R677) Passenger Head Restraint Solenoid Signal circuit for an open or high resistance.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  5. CHECK THE (Z919) ACTIVE HEAD RESTRAINT 1ST ROW PASSENGER GROUND CIRCUIT FOR AN OPEN 
    Fig 2: Checking Active Head Restraint 1st Row Passenger Ground Circuit For An Open

    1. Measure the resistance of the (Z919) Active Head Restraint 1st Row Passenger Ground circuit between the Active Head Restraint 1st Row Passenger connector and ground.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Go To  6

      No 

  6. CHECK OPERATION OF THE PASSENGER HEAD RESTRAINT 
    1. Replace the Passenger Head Restraint in accordance with the Service Information. Refer to HEADREST, FRONT, REMOVAL .
    2. Reconnect the vehicle body harness to the Passenger Head Restraint harness connector.
