      Tech Tips

      A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the accessory meter assembly*1 or multi-display assembly*2 with the connector connected.


      1. Waveform 1

        Item Content
        Terminal No. (Symbol) S31-3 (CV+) - S31-2 (CV-)
        Tool setting 200 mV/DIV., 50 μsec./DIV.
        Condition

        Engine switch on (IG)

        Shift lever in R

        Camera lens not covered, displaying image

        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).

      2. Waveform 2

        Item Content
        Terminal No. (Symbol) S31-3 (CV+) - S31-2 (CV-)
        Tool setting 200 mV/DIV., 50 μsec./DIV.
        Condition

        Engine switch on (IG)

        Shift lever in R

        Camera lens covered, blacking out screen

        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).
