PARKING ASSIST MONITOR SYSTEM(for Navigation Receiver Type) TERMINALS OF ECU


  1. REAR TELEVISION CAMERA ASSEMBLY


    1. A00YXK8E02

      Disconnect the U6 television camera assembly.

    2. Measure the voltage and resistance 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 Ignition switch ON Shift lever in R 5.5 to 7.05 V
      U6-1 (CURT) - Body ground W - Body ground Ground Always Below 1 Ω

    3. Reconnect the U6 television camera assembly connector.

    4. Check for pulses between each terminal of the connector.

      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 navigation ECU sub-assembly with the connector connected. If the result is not as specified, the television camera assembly may have a malfunction.

      Tech Tips

      A waterproof connector is used for the television camera assembly. Therefore, inspect the waveform at the navigation ECU sub-assembly with the connector connected.


      1. Waveform 1 (camera lens is not covered, displaying an image)

        Item Content
        Terminal No. (Symbol) U6-3 (CV+) - U6-5 (CGND)
        Tool Setting 200 mV/DIV., 50 μsec./DIV.
        Condition Ignition switch ON, shift lever in R

        Tech Tips

        The video waveform changes according to the image sent by the television camera assembly.

      2. Waveform 2 (camera lens is covered, blacking out the screen)

        Item Content
        Terminal No. (Symbol) U6-3 (CV+) - U6-5 (CGND)
        Tool Setting 200 mV/DIV., 50 μsec./DIV.
        Condition Ignition switch ON, shift lever in R

        Tech Tips

        The video waveform changes according to the image sent by the television camera assembly.
