   *2	Front view of wire harness connector (to Rear Television Camera Assembly)

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Replace the digital cable between the parking assist ECU and display and navigation module display with a new one.

NEXT: Go to next step 

1. Turn the engine switch on (IG).
2. When the shift lever is moved to R, check that the image displays normally on the screen.

   OK

   Image displays normally on the screen.
