  1. CHECK HARNESS AND CONNECTOR (RADIO AND DISPLAY RECEIVER ASSEMBLY - REAR TELEVISION CAMERA ASSEMBLY)


    1. Disconnect the I154 connector from the radio and display receiver assembly.

    2. Disconnect the T6 connector from the rear television camera assembly.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      I154-8 (V+) - T6-3 (CV+) Always Below 1 Ω
      I154-7 (CA+) - T6-6 (CB+) Always Below 1 Ω
      I154-15 (CGND) - T6-5 (CGND) Always Below 1 Ω
      I154-16 (V-) - T6-2 (CV-) Always Below 1 Ω
      I154-8 (V+) - Body ground Always 10 kΩ or higher
      I154-7 (CA+) - Body ground Always 10 kΩ or higher
      I154-16 (V-) - Body ground Always 10 kΩ or higher
      I154-15 (CGND) - Body ground Always 10 kΩ or higher

      *a

      Component with harness connected

      (Radio and Display Receiver Assembly)
      *b Waveform 1 (camera lens not covered, displaying an image)
      *c Waveform 2 (camera lens covered, blacking out the screen)
      *d Synchronization Signal
      *e Video Waveform

      Check the waveform of the rear 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 radio and display receiver assembly with the connector connected.

      OK
      Waveform is similar to that shown in the illustration.
      Item Content
      Terminal No. (Symbol) I154-8 (V+) - I152-7 (GND1)
      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 rear television camera assembly.
