      *c Waveform B *d Synchronized Signal
      *e Video Waveform - -

      Tech Tips


      • A waterproof connector is used for the side television camera assembly. Therefore, inspect the waveform at the navigation receiver assembly*1 or radio and display receiver assembly*2 with the connector connected.


        • *1: for Navigation Receiver Type

        • *2: for Radio and Display Type

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

      Measurement Condition
      Item Content
      Tester Connection I7-10 (SCV+) - I7-33 (SGND)
      Tool Setting 200 mV/DIV., 50 μsec./DIV.
      Condition
      • Waveform A: Engine switch on (IG), wide view front and side monitor switch on, camera lens not covered, displaying image

      • Waveform B: Engine switch on (IG), wide view front and side monitor switch on, camera lens covered, blacking out screen

      OK
      Waveform is as shown in illustration.
