Circuit/System Description

When the rear compartment lid unlatch switch is pressed, the rear compartment lid release signal circuit to the body control module is grounded. When the rear compartment lid release signal circuit is grounded, the body control module grounds the coil side of the rear compartment lid unlatch relay through the relay control circuit. With ground applied to the coil side of the rear compartment lid unlatch relay, voltage is applied to the rear compartment lid latch, opening the rear compartment.
