Circuit Operation

Voltage is applied from the TRUNK RELEASE fuse to the trunk lid release relay. With the valet switch on and the Park/Neutral Position (PNP) switch in "PARK" or "NEUTRAL" position, pressing the trunk lid release switch energizes the relay. The relay can also be actuated, regardless of the valet switch position and PNP switch position, using the keyless entry transmitter. The Remote Function Actuator (RFA) module provides a ground path to energize the relay when the trunk lid release button on the keyless entry transmitter is pressed. When energized, the relay applies voltage to the trunk lid release actuator, releasing the trunk lid.

The trunk lid release actuator is protected by a diode for surge protection and a positive temperature coefficient device for voltage protection.
