Exterior Liftgate/Luggage Compartment Lid Release Switch

The exterior liftgate/luggage compartment lid release switch is a momentary contact switch that supplies a ground signal to the BCM  and, if equipped, the RFA  module. When the switch is pressed, the signal is routed to ground, indicating a request to the BCM  to release the liftgate/luggage compartment lid latch or for the RFA  module to initiate the passive entry feature.
