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
   X12-6 (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 X12 television camera assembly connector.
4. Check for pulses between each terminal of the connector.

   Terminal No. (Symbol)	Wiring Color	Terminal Description	Condition	Specified Condition
   X12-3 (CV+) - X12-2 (CV-)	R - W	Video signal	Power switch on (IG) Shift lever in R Camera lens not covered, displaying image	Pulse generation (Refer to waveform  1)
   			Power switch on (IG) Shift lever in R Camera lens covered, blacking out screen	Pulse generation (Refer to waveform  2)

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

   HINT: 

   • The video waveform changes according to the image sent by the television camera assembly.
   • The video waveform is constantly output when the power switch is on (ACC).

   *a	Waveform 1 (camera lens is not covered, displaying an image)
   *b	Waveform 2 (camera lens is covered, blacking out the screen)
   *c	Synchronization Signal
   *d	Video Waveform

   HINT: 

   A waterproof connector is used for the television camera assembly. Therefore, inspect the waveform at the navigation receiver assembly*1 or radio and display receiver assembly*2 with the connector connected.

   • *1: for Navigation Receiver Type
   • *2: for Radio and Display Type

   If the result is not as specified, the television camera assembly may be malfunctioning.
