PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (INNER REAR VIEW MIRROR ASSEMBLY - REAR TELEVISION CAMERA ASSEMBLY)


    1. Disconnect the T9 inner rear view mirror assembly connector.

    2. Disconnect the V14 rear television camera assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      T9-7 (CV+) - V14-3 (CV+) Always Below 1 Ω
      T9-14 (CB+) - V14-6 (CB+) Always Below 1 Ω
      T9-6 (CV-) - V14-2 (CV-) Always Below 1 Ω
      T9-13 (CGND) - V14-5 (CGND) Always Below 1 Ω
      T9-7 (CV+) - Body ground Always 10 kΩ or higher
      T9-14 (CB+) - Body ground Always 10 kΩ or higher
      T9-6 (CV-) - Body ground Always 10 kΩ or higher
      T9-13 (CGND) - Body ground Always 10 kΩ or higher

    NG
    OK
  2. INSPECT INNER REAR VIEW MIRROR ASSEMBLY

      Component with harness connected

      (Inner Rear View Mirror Assembly)

      Reconnect the T9 inner rear view mirror assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      T9-6 (CV-) - Body ground Always Below 1 Ω
      T9-13 (CGND) - Body ground Always Below 1 Ω
    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      T9-14 (CB+) - T9-13 (CGND)

      Power switch on (READY)

      Reverse (R) selected

      5.5 to 7.05 V

    NG
    OK

      *b Waveform 2 (camera lens is covered, blacking out the screen)
      *c Synchronization Signal
      *d Video Waveform

      Using an oscilloscope, check the waveform of the rear television camera assembly.

      Tech Tips

      A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the inner rear view mirror assembly with the connector connected.

      OK
      Waveform is similar to that shown in the illustration.
      Item Content
      Measurement terminal T9-7 (CV+) - T9-2 (E)
      Measurement setting 200 mV/DIV., 50 μs./DIV.
      Condition Power switch on (READY), reverse (R) selected

      Tech Tips

      The video waveform changes according to the image sent by the rear television camera assembly.
