Normal Operation
When the power liftgate (PLG) moves in the close direction, the PLG module monitors the pinch strips and position sensor for obstacle detection. The PLG module uses a 5-volt reference signal on circuit CPR52 (YE/VT) and a return signal on circuit RPR52 (VT/GY) for the left pinch strip. The PLG module uses a 5-volt reference signal on circuit CPR51 (YE/OG) and a return signal on circuit RPR52 (VT/GY) for the right pinch strip. The right and left pinch strip return signal circuits are spliced together.
