      Tech Tips

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

      OK
      Waveform is as shown in the illustration.
      Item Content
      Terminal No. (Symbol) F76-12 (V+) - F67-7 (GND1)
      Tool Setting 200 mV/DIV., 50 μsec./DIV.
      Condition Ignition switch ON (IG), shift lever in R

      Tech Tips

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