PARKING ASSIST MONITOR SYSTEM TERMINALS OF ECU


  1. CHECK MULTI-MEDIA MODULE RECEIVER ASSEMBLY

    A01FTPAE45

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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      N164-39 (CA+) - N164-40 (CGND) B - Shielded Power source Hybrid control system starts, shift lever in R 5.5 to 7.05 V
      N164-18 (V+) - N164-40 (CGND) R - Shielded Display signal Hybrid control system starts, shift lever in R Pulse generation (See waveform)
      N164-19 (V-) - N164-40 (CGND) W - Shielded Rear television camera assembly ground Always Below 1 V
      N164-40 (CGND) - Body ground Shielded - Body ground Shielding Always Below 1 V
      N164-17 (+B1) - N164-12 (GND1) L - W-B Battery power source Always 11 to 14 V
      N164-12 (GND1) - Body ground W-B - Body ground Ground Always Below 1 Ω
      N164-1 (CANH) B CAN communication line - -
      N164-2 (CANL) W CAN communication line - -

    2. Using an oscilloscope, check waveform.

      Item Content
      Terminal No. (Symbol) N164-18 (V+) - N164-40 (CGND)
      Tool Setting 0.2 V/DIV., 50 μs/DIV.
      Condition

      Waveform A: Hybrid control system starts, shift lever in R (camera lens is not covered, displaying an image)

      Waveform B: Hybrid control system starts, shift lever in R (camera lens is covered, blacking out the screen)

      Tech Tips

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