    REAR TELEVISION CAMERA ASSEMBLY


    1. Disconnect the L202 rear television camera assembly connector.

    2. Measure the voltage on the wire harness side connector according to the value(s) in the table below.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      L202-6 (CB+) - Body ground GR - Body ground Power source Power switch on (ACC) 5.5 to 7.05 V

    3. Reconnect the L202 rear television camera assembly connector.

    4. Measure the voltage, resistance and waveform according to the value(s) in the table below.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      L202-2 (CV-) - Body ground G - Shielded Ground Always Below 1 Ω
      L202-3 (CV+) - L202-2 (CV-) B - G Video signal Power switch on (READY), shift lever in R, camera lens is not covered, displaying an image Pulse generation (See waveform 1)
      Power switch on (READY), shift lever in R, camera lens is covered, blacking out screen Pulse generation (See waveform 2)
      L202-5 (CGND) - Body ground BR - Body ground Shielded ground Always Below 1 Ω
    5. B004Y08C03
      *a Waveform 1
      *b Waveform 2
      *c Synchronization Signal
      *d Video Waveform

      Reference (Waveform):

      Tip:

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


      1. Waveform 1

        Item Content
        Terminal No. (Symbol) L202-3 (CV+) - L202-2 (CV-)
        Tool Setting 200 mV/DIV., 50 μsec./DIV.
        Condition Power switch on (IG), shift lever in R, camera lens is not covered, displaying an image
        Tip:

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

      2. Waveform 2

        Item Content
        Terminal No. (Symbol) L202-3 (CV+) - L202-2 (CV-)
        Tool Setting 200 mV/DIV., 50 μsec./DIV.
        Condition Power switch on (IG), shift lever in R, camera lens is covered, blacking out screen
        Tip:

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