PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (TELEVISION CAMERA ASSEMBLY - MULTI-DISPLAY)


    1. Disconnect the d1 television camera assembly connector.

    2. Disconnect the P42 multi-display connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      P42-10 (CA+) - d1-8 (CB+) Always Below 1 Ω
      P42-8 (V+) - d1-4 (CV+) Always Below 1 Ω
      P42-9 (V-) - d1-3 (CV-) Always Below 1 Ω
      P42-21 (CGND) - d1-7 (CGND) Always Below 1 Ω
      P42-10 (CA+) or d1-8 (CB+) - Body ground Always 10 kΩ or higher
      P42-8 (V+) or d1-4 (CV+) - Body ground Always 10 kΩ or higher
      P42-9 (V-) or d1-3 (CV-) - Body ground Always 10 kΩ or higher
      P42-21 (CGND) or d1-7 (CGND) - Body ground Always 10 kΩ or higher
      P42-20 (CSLD) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. CHECK MULTI-DISPLAY (CA+, CGND)


    1. B000XJZC01
      *a

      Component with harness connected

      (Multi-display)

      Remove the multi-display with the connector still connected.

      Click here

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      P42-10 (CA+) - P42-21 (CGND) Engine switch on (ACC) 5.5 to 7.05 V

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      P42-21 (CGND) - Body ground Always Below 1 Ω
      Result
      Proceed to
      OK

  3. CHECK TELEVISION CAMERA ASSEMBLY

    B000Z66C02
    *a

    Component with harness connected

    (Multi-display)

    		 *b Waveform 1
    *c Waveform 2 *d Synchronization Signal
    *e Video Waveform - -

    1. Remove the multi-display with the connector still connected.

      Click here

    2. Check the waveform of the television camera assembly using an oscilloscope.

      Item Content
      Measurement terminal P42-8 (V+) - P42-9 (V-)
      Measurement setting 200 mV/DIV., 50 μsec./DIV.
      Condition

      Waveform 1: Engine running, shift position in R, camera lens is not covered, displaying an image.

      Waveform 2: Engine running, shift position in R, camera lens is covered, blacking out the screen.

      Tech Tips


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

      • The video waveform is constantly output when the engine switch is on (ACC).

      OK
      Waveform is as shown in the illustration.
