Power Trunk / Liftgate Hazard Sensor: Description and Operation
Pinch sensors are located on each side of the lift-gate. These sensors look like weather-strips, however they consist of pieces of electrically conductive
rubber (tapeswitch), wires, resistor, double sided tape, and a plastic carrier. They are used to indicate an obstruction during a power liftgate close cycle.
During a power liftgate close cycle, if either of the two conductive rubber strips (tapeswitch) of the pinch sensor come in contact with an obstacle, the
pinch sensor circuit is completed. This tells the power liftgate control module that a obstruction is felt. The control module will stop the liftgate
immediately and return it to the full open position.
