TERMINALS OF ECU

1. CHECK REAR TELEVISION CAMERA ASSEMBLY

(a) Disconnect the S5 camera connector.

(b) Measure the voltage and resistance according to the value(s) in the table below.

Terminal No. (Symbol)	Wiring Color	Terminal Description	Condition	Specified Condition
S5-3 (CGND) - Body ground	W - Body ground	Ground	Always	Below 1 Ω
S5-4 (CB+) - S5-3 (CGND)	B - W	Power source	Engine switch on (IG), shift lever in R	5.8 to 6.5 V

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

(d) Measure the voltage according to the value(s) in the table below.

Terminal No. (Symbol)	Wiring Color	Terminal Description	Condition	Specified Condition
S5-2 (CV+) - S5-1 (CV-)	R - BR	Display signal	Engine switch on (IG), shift lever in R	Waveform 1

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

(e) Using an oscilloscope, check waveform 1.
