Measure the voltage and resistance between each terminal of the wire harness side connector.

TELEVISION CAMERA ASSEMBLY VOLTAGE AND RESISTANCE

Symbols (Terminal No.)	Wiring Color	Terminal Description	Condition	Specified Condition
CGND (T13-3) - Body ground	W - Body ground	Ground	Always	Below 1 Ω
CB+ (T13-4) - CGND (T13-3)	B - W	Power source	Power switch ON (IG), shift lever R position	Approx. 6 V

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

Measure the voltage and frequency between each terminal of the connector.

TELEVISION CAMERA ASSEMBLY VOLTAGE

Symbols (Terminal No.)	Wiring Color	Terminal Description	Condition	Specified Condition
CV+ (T13-2) - CV - (T131)	R - Shielded	Display signal	Power switch ON (IG), shift lever R position	See waveform 1

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

Using an oscilloscope, check the waveform
