  4. INSPECT TELEVISION CAMERA ASSEMBLY


    1. Reconnect the Q43 connector to the television camera assembly.

      A0160W9E01
    2. A0161YIE01

      Check the waveform of the television camera assembly using an oscilloscope.

      Item Content
      Measurement terminal Q43-2 (CV+) - Q43-1 (CV-)
      Measurement setting 0.2 V/DIV., 50 μsec./DIV.
      Condition Engine switch on (IG), shift lever in R
      OK
      Pulses are as shown in the illustration.

      Tech Tips


      • For waveform 1, the cycle is approximately 63.6 μsec and the waveform is almost entirely longitudinal.

      • For waveform 2, the cycle is approximately 63.6 μsec and the waveform is almost flat.
