INSPECTION PROCEDURE

Note


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


    w/ G-BOOK System:

  • When replacing the multi-media module receiver assembly or telematics transceiver, perform vehicle contract setting (w/ Telematics Transceiver) Click here.

  • When replacing the multi-media module receiver assembly, perform vehicle contract setting (w/o Telematics Transceiver) Click here.

PROCEDURE


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


    1. Disconnect the G35 multi-media module receiver assembly connector.

    2. Disconnect the O42 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
      G35-3 (CNH1) - O42-5 (MO+) Always Below 1 Ω
      G35-4 (CNL1) - O42-4 (MO-) Always Below 1 Ω
      G35-3 (CNH1) - Body ground Always Below 1 Ω
      G35-4 (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 O42 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
      O42-1 (+B) - Body ground Power switch off 11 to 14 V
      O42-2 (ACC) - Body ground Power 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
      O42-15 (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)


    1. A01NLDRE01
      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 power switch is turned on (ACC), feedback force is generated. When the power switch is turned off, feedback force is not generated, and the remote touch switch knob will move freely.
