      *b Waveform 2 (camera lens covered, blacking out the screen)
      *c Synchronization Signal
      *d Video Waveform

      Check the waveform of the 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 navigation receiver assembly with the connector connected.

      OK
      Waveform is similar to that shown in the illustration.
      Item Content
      Terminal No. (Symbol) E3-22 (V+) - E6-7 (GND)
      Tool Setting 200 mV/DIV., 50 μsec./DIV.
      Condition Ignition switch ON, shift lever in R

      Tech Tips

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