REAR VIEW MONITOR SYSTEM TERMINALS OF ECU

REAR TELEVISION CAMERA ASSEMBLY

1. 

   Disconnect the P9 rear television camera assembly connector.

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

   Terminal No. (Symbol)	Wiring Color	Terminal Description	Condition	Specified Condition
   P9-6 (CB+) - Body ground	R - Body ground	Power source	Ignition switch ON 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. Reconnect the rear television camera assembly connector.

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

   Terminal No. (Symbol)	Wiring Color	Terminal Description	Condition	Specified Condition
   P9-3 (CV+) - P9-2 (CV-)	B - W	Display 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)

   Tip:

   A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the radio and display assembly with the connector connected.

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

5. 

   Reference (Oscilloscope waveform):

   Tip:

   A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the radio and display assembly with the connector connected.

   
   

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

      Item	Content
      Terminal No. (Symbol)	P9-3 (CV+) - P9-2 (CV-)
      Tool Setting	200 mV/DIV., 50 μsec./DIV.
      Condition	Ignition switch ON, shift lever in R

      Tip:

      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)	P9-3 (CV+) - P9-2 (CV-)
      Tool Setting	200 mV/DIV., 50 μsec./DIV.
      Condition	Ignition switch ON, shift lever in R

      Tip:

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