      *d Video Waveform

      Using an oscilloscope, check the waveform of the television camera assembly.

      Tech Tips

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

      OK
      Waveform is similar to that shown in the illustration.

      Measurement terminal F72-12 (V+) - F69-7 (GND1)
      Measurement setting 200 mV/DIV., 50 μs./DIV.
      Condition Engine switch on (IG), shift lever in R

      Tech Tips


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

      • The video waveform is constantly output when the engine switch is on (ACC).
