PARKING ASSIST MONITOR SYSTEM(w/ Parallel Parking Assist Function) TERMINALS OF ECU

REAR TELEVISION CAMERA ASSEMBLY

1. 

   Disconnect the U6 rear television camera assembly connector.

2. Measure the voltage on the wire harness side connector 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	Power switch on (ACC)	5.5 to 7.05 V

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

3. Reconnect the U6 rear television camera assembly connector.

4. Measure the voltage and check for pulses at 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	Power switch on (IG) Shift lever in R Camera lens not covered, displaying image	Pulse generation (See waveform 1)
   			Power switch on (IG) Shift lever in R Camera lens covered, blacking out screen	Pulse generation (See waveform 2)
   U6-5 (CGND) - Body ground	BR - Body ground	Shield ground	Always	Below 1 V

   Tip:

   A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the multi-media module receiver assembly with the connector connected.

   If the result is not as specified, the rear television camera assembly may have a malfunction.

   Reference (Oscilloscope waveform):

   Tip:

   A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the multi-media module receiver assembly with the connector connected.

   
   

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

      Item	Content
      Measurement terminal	U6-3 (CV+) - U6-2 (CV-)
      Measurement setting	200 mV/DIV., 50 μs./DIV.
      Condition	Power switch on (IG), shift lever in R

      Tip:
      

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

      • The video waveform is constantly output when the power switch is on (ACC).

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

      Item	Content
      Measurement terminal	U6-3 (CV+) - U6-2 (CV-)
      Measurement setting	200 mV/DIV., 50 μs./DIV.
      Condition	Power switch on (IG), shift lever in R

      Tip:
      

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

      • The video waveform is constantly output when the power switch is on (ACC).
