PARKING ASSIST MONITOR SYSTEM TERMINALS OF ECU

  1. REAR TELEVISION CAMERA ASSEMBLY

    1. Disconnect the T6 connector from the rear television camera assembly.

      A011SI0E01

    2. Measure the voltage of each terminal of the wire harness side connector.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      T6-6 (CB+) - Body ground B - Body ground Power source

      Engine switch on (IG)

      Shift lever in R

      		 5.5 to 7.05 V

      If the result is not as specified, there may be a malfunction on the wire harness side.

    3. Measure the resistance according to the value(s) in the table below.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      T6-1 (CURT) - Body ground BR - Body ground Ground Always Below 1 Ω

      If the result is not as specified, there may be a malfunction on the wire harness side.

    4. Reconnect the T6 connector to the rear television camera assembly.

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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      T6-3 (CV+) - T6-2 (CV-) W - R Video signal

      Engine switch on (IG)

      Shift lever in R

      Camera lens not covered, displaying an image

      Pulse generation

      (See waveform 1)

      Engine switch on (IG)

      Shift lever in R

      Camera lens covered, blacking out screen

      Pulse generation

      (See waveform 2)

      Tech Tips

      A waterproof connector is used for the rear 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 rear television camera assembly may have a malfunction.

    6. Reference (Oscilloscope waveform):

      A011TH5E22

      Tech Tips

      A waterproof connector is used for the rear 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) T6-3 (CV+) - T6-2 (CV-)
        Tool Setting 200 mV/DIV., 50 μsec./DIV.
        Condition Engine switch on (IG), shift lever in R

        Tech Tips

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

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

        Item Content
        Terminal No. (Symbol) T6-3 (CV+) - T6-2 (CV-)
        Tool Setting 200 mV/DIV., 50 μsec./DIV.
        Condition Engine switch on (IG), shift lever in R

        Tech Tips

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

  2. CHECK INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY AND MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU)

    A011QP5E04

    1. Measure the voltage and check for pulses according to the value(s) in the table below.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      3C-9 - Body ground W - Body ground Luggage compartment door courtesy light switch input Luggage compartment door open Below 1 V
      Luggage compartment door closed 11 to 14 V

      If the result is not as specified, the main body ECU (multiplex network body ECU) or instrument panel junction block assembly may have a malfunction.
