  1. TELEVISION CAMERA ASSEMBLY


    1. A00YXK8E01

      Disconnect the U6 television camera assembly connector.

    2. Measure the voltage according to the value(s) in the table below.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      U6-6 (CB+) - Body ground B - Body ground Power source Within 60 seconds of turning the ignition switch to ACC 5.5 to 7.05 V

    3. Reconnect the U6 television camera assembly connector.

    4. Measure the voltage and waveform according to the value(s) in the table below.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      U6-3 (CV+) - U6-2 (CV-) W - R Video signal

      Ignition switch ON

      Shift lever in R

      Camera lens not covered, displaying an image

      Pulse generation

      (See waveform 1)

      Ignition switch ON

      Shift lever in R

      Camera lens covered, blacking out screen

      Pulse generation

      (See waveform 2)

      Tech Tips

      A waterproof connector is used for the television camera assembly. Therefore, inspect the waveform at the radio and display receiver assembly*1 or navigation ECU sub-assembly*2 with the connector connected.
