INSPECTION PROCEDURE

PROCEDURE


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


    1. Disconnect the E9 clock assembly.

    2. Disconnect the T16 television camera assembly.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      T16-2 (CV+) - E9-14 (V+) Always Below 1 Ω
      T16-3 (CGND) - E9-4 (CGND) Always Below 1 Ω
      T16-4 (CB+) - E9-12 (CA+) Always Below 1 Ω
      T16-1 (CV-) - E9-15 (V-) Always Below 1 Ω
      T16-2 (CV+) - Body ground Always 10 kΩ or higher
      T16-3 (CGND) - Body ground Always 10 kΩ or higher
      T16-4 (CB+) - Body ground Always 10 kΩ or higher
      T16-1 (CV-) - Body ground Always 10 kΩ or higher

    NG

      *a Waveform 1 (camera lens not covered, displaying an image)
      *b Waveform 2 (camera lens covered, blacking out the screen)
      *c Synchronization Signal
      *d Video Waveform

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

      Tech Tips

      A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the navigation receiver assembly with the connector connected.

      OK
      Waveform is similar to that shown in the illustration.
      Item Content
      Terminal No. (Symbol) E9-14 (V+) - E9-5 (GND)
      Tool Setting 200 mV/DIV., 50 μsec./DIV.
      Condition Ignition switch ON, shift lever in R

      Tech Tips

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