  • Inspect the fuses for circuits related to this system before performing the following inspection procedure.

  • Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precautions for Navigation System Click here.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (MULTI-MEDIA MODULE RECEIVER ASSEMBLY - REMOTE TOUCH (REMOTE OPERATION BOARD) )


    1. Disconnect the H97 multi-media module receiver assembly connector.

    2. Disconnect the H95 remote touch (remote operation board) connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      H97-3 (CNH1) - H95-5 (MO+) Always Below 1 Ω
      H97-4 (CNL1) - H95-4 (MO-) Always Below 1 Ω
      H97-3 (CNH1) - Body ground Always Below 1 Ω
      H97-4 (CNL1) - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. CHECK HARNESS AND CONNECTOR (REMOTE TOUCH (REMOTE OPERATION BOARD) POWER SOURCE)


    1. Disconnect the H95 remote touch (remote operation board) connector.

    2. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      H95-1 (+B) - Body ground Always 11 to 14 V
      H95-2 (ACC) - Body ground Engine switch on (ACC) 11 to 14 V

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      H95-15 (GND) - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. REMOTE TOUCH SELF CHECK (REMOTE TOUCH SWITCH KNOB FEEDBACK FORCE GENERATION CHECK)

      Text in Illustration
      *a Switch Knob
      *b Control Direction
      *c Feedback Force

      Check the remote touch switch knob feedback force.


      1. Move the remote touch switch knob up, down, right and left to check that feedback force is generated.

        OK
        Feedback force is generated.

        Tech Tips

        When the engine switch is turned on (ACC), feedback force is generated. When the engine switch is turned off, feedback force is not generated, and the remote touch switch knob will move freely.
