PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (TELEVISION CAMERA CONTROLLER - REAR TELEVISION CAMERA ASSEMBLY)


    1. Disconnect the R124 television camera controller connector.

    2. Disconnect the m4 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
      R124-1 (CV+) - m4-3 (CV+) Always Below 1 Ω
      R124-2 (CV-) - m4-2 (CV-) Always Below 1 Ω
      R124-9 (CGND) - m4-5 (CGND) Always Below 1 Ω
      R124-1 (CV+) or m4-3 (CV+) - Body ground Always 10 kΩ or higher
      R124-2 (CV-) or m4-2 (CV-) - Body ground Always 10 kΩ or higher
      R124-9 (CGND) or m4-5 (CGND) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

  2. CHECK HARNESS AND CONNECTOR (ACC POWER SUPPLY - GROUND)


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

      Standard Voltage
      Tester Connection Condition Specified Condition
      m4-6 (CB+) - Body ground Engine switch on (ACC) 11 to 14 V
      Result
      Proceed to
      OK

  4. CHECK REAR TELEVISION CAMERA ASSEMBLY (CV+, CGND)


    1. Remove the television camera controller with the connector still connected.

    2. 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 television camera controller with the connector connected.

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

      Tech Tips


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

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