Back Monitor System: Pre-Check

  1. INSPECT TELEVISION CAMERA ASSY 
    1. Standard signal check.
      1. Using the tester, measure the voltage and check the continuity between terminals.

        HINT:

        Leave the connector being connected.

      2. Using the oscilloscope, check waveforms between terminals.

      HINT:

      • Leave the connector being connected.
      • The waveform shown is merely an example.

        Noise waveform and chattering waveform are omitted.
