      (Navigation Receiver Assembly)
      A01MG2UC09
      *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

      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 navigation receiver assembly with the connector connected.

      OK
      Waveform is similar to that shown in the illustration.
      Item Content
      Measurement terminal G106-12 (V+) - G106-24 (V-)
      Measurement setting 200 mV/DIV., 50 μs./DIV.
      Condition Power 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 power switch on (ACC).
