Normal Operation
When the power liftgate moves in the close direction, the PLG module monitors the pinch strips and optical sensor for obstacle detection. The PLG module uses a 5-volt reference signal on circuit 1966 (LB/BK) and a return signal on circuit 1967 (GY/OG) for the left pinch strip. The PLG module uses a 5-volt reference signal on circuit 1965 (VT) and a return signal on circuit 1967 (GY/OG) for the right pinch strip. The right and left pinch strip return signal circuits are spliced together.

NOTE: Initialize the power liftgate before proceeding with this pinpoint test. Refer to Power Liftgate Initialization.
