2. Disconnect the Y8 camera connector.
3. Measure the resistance of the wire harness side connectors.

   Standard resistance

   Tester Connection	Specified Condition
   K47-13 (CA+) - Y8-4 (CB+)	Below 1 Ω
   K47-14 (CGND) - Y8-3 (CGND)	Below 1 Ω
   K47-27 (V+) - Y8-2 (CV+)	Below 1 Ω
   K47-28 (V-) - Y8-1 (CV-)	Below 1 Ω
   K47-13 (CA+) - Body ground	10 kΩ or higher
   K47-14 (CGND) - Body ground	10 kΩ or higher
   K47-27 (V+) - Body ground	10 kΩ or higher
   K47-28 (V-) - Body ground	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Reconnect the K47 display connector.
2. Measure the voltage of the connector.

   Standard voltage

   Tester Connection	Condition	Specified Condition
   Y8-4 (CB+) - Y8-3 (CGND)	Power switch ON (IG), shift lever in R position	Approx. 6 V

NG → REPLACE MULTI-DISPLAY 

OK: Go to next step 

1. Reconnect the Y8 camera connector.
2. Check the waveform of the camera using an oscilloscope.

   OK

   Waveform is as shown in the illustration.
