Switch, Deck Lid Release: Operation: DECKLID

WARNING: This page is about a different car, the 2020 Chrysler 300 and 2019 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

The Passive Entry (PE) decklid release switch is a normally open switch that is connected to ground at all times. When the switch button is depressed, it provides a ground signal to the Body Control Module (BCM) through a decklid release switch sense circuit. In response to that input, the BCM sends an electronic unlock request message to the Radio Frequency Hub (RF-Hub) over the Controller Area Network (CAN) data bus. The RF-Hub determines the PE system response based upon the inputs it receives through the authentication process with each detected Finger Operated Button Integrated Key (FOBIK).

The diagnostic resistor integral to the output side of the switch enables the BCM to monitor the condition of the decklid release switch and switch sense circuit. The BCM will store a Diagnostic Trouble Code (DTC) for any fault that is detected in this circuit.
