      *a Waveform 1 (camera lens is not covered, displaying an image)
      *b Waveform 2 (camera lens is covered, blacking out the screen)
      *c Synchronization Signal
      *d 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 inner rear view mirror assembly with the connector connected.

      OK
      Waveform is as shown in the illustration.
      Item Content
      Terminal No. (Symbol) T5-7 (CV+) - Body ground
      Tool Setting 200 mV/DIV., 50 μsec./DIV.
      Condition Power switch on (IG), shift lever in R

      Tech Tips

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