      T5-14 (CB+) - T5-13 (CGND)

      Power switch on (IG)

      Shift lever in R

      5.8 to 7.0 V

    NG
    OK
  3. CHECK REAR TELEVISION CAMERA ASSEMBLY


    1. Reconnect the Y14 connector to the rear television camera assembly.

      *1

      Component with harness connected

      (Inner Rear View Mirror Assembly)

      *2 Waveform 1 (under normal conditions)
      *3 Waveform 2 (camera lens is covered, blacking out the screen)
      *4 Synchronized Signal
      *5 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+) - T5-2 (E)
      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.
