WARNING: This page is about a different car, the 2004 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT TELEVISION CAMERA ASSY 
    1. Standard signal check.
      1. Using the tester, measure the voltage and check the continuity between terminals.
        NOTE: Leave the connector being connected.
      2. Using the oscilloscope, check waveforms between terminals.
      NOTE:
      • Leave the connector being connected.
      • The waveform shown is merely an example.

        Noise waveform and chattering waveform are omitted.
