Instrument Panel Switch

INSTRUMENT PANEL

The instrument panel deck lid 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) (also known as the Common Body Controller/CBC) through a deck lid release switch sense circuit.

The BCM uses internal programming and inputs from other sources to determine the appropriate response to an instrument panel deck lid release switch input. If the vehicle has an automatic transmission, the BCM must confirm that the transmission gear selector lever is in the PARK position before activating the deck lid latch motor. If the vehicle is equipped with a manual transmission, the BCM must confirm that the vehicle speed input is less than 8 kilometers-per-hour (5 miles-per-hour) before activating the deck lid latch motor.

The hard wired circuits between the instrument panel deck lid release switch and the BCM may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the switch or the electronic controls and communication between other modules and devices that provide the deck lid release feature. The most reliable, efficient, and accurate means to diagnose the deck lid release feature or the electronic controls and communication related to instrument panel deck lid release switch operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
