      *a Waveform A (camera lens not covered, displaying an image)
      *b Waveform B (camera lens covered, blacking out the screen)
      *c Synchronized Signal
      *d Video Waveform

      Tech Tips

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


      1. Waveform

        Item Content
        Terminal No. (Symbol) F76-15 (CV+) - F75-37 (CGND)
        Tool Setting 200 mV/DIV., 50 μsec./DIV.
        Condition

        • Waveform A: Engine switch on (IG), shift lever in R and camera lens is not covered, displaying an image.

        • Waveform B: Engine switch on (IG), shift lever in R and camera lens is covered, blacking out the screen.

  2. REAR TELEVISION CAMERA ASSEMBLY

    A01XB3AE02

    1. Disconnect the S5 rear television camera assembly connector.

    2. Measure the voltage and resistance according to the value(s) in the table below.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      S5-3 (CGND) - Body ground BR - Body ground Ground Always Below 1 Ω
      S5-4 (CB+) - S5-3 (CGND) B - BR Power source Engine switch on (IG), shift lever in R 5.5 to 7.05 V

    3. Reconnect the S5 rear television camera assembly connector.

      Tech Tips

      A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the parking assist ECU with the connector connected. If the result is not as specified, the rear television camera assembly may have a malfunction.

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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      S5-2 (CV+) - S5-3 (CGND) R - BR Display signal Engine switch on (IG), shift lever in R Pulse generation (See waveform)
