Trunk / Liftgate Solenoid: Description and Operation
CIRCUIT OPERATIONWithout Remote Keyless Entry
The deck lid release system uses a switch, located in the center console, and a release solenoid located on the deck lid latch assembly.
Power for the switch is supplied on circuit F35. This circuit is HOT at all times and protected by a 20 Amp circuit breaker located in cavity 18 of the junction block. The F35 circuit is spliced and supplies power for the power seats.
Power for the circuit breaker is supplied on circuit A3. This circuit is HOT at all times and protected by a 40 Amp fuse located in cavity 15 of the Power Distribution Center (PDC).
When the switch is CLOSED, power flows through the switch to circuit Q2. The Q2 circuit connects from the switch to the deck lid release solenoid. Ground for the solenoid is supplied on circuit Z1.
With Remote Keyless Entry
On vehicles equipped with Remote Keyless Entry (RKE) a relay is placed in the F35 and Q2 circuits. This relay allows the operator to unlock the trunk with the RKE transmitter. Power for the coil and contact sides of the relay is supplied on circuit F35. Ground for the coil side of the relay is controlled by the Body Control Module (BCM).
When the RKE transmitter is activated the BCM provides a ground path for circuit Q33. This causes the contacts in the relay to CLOSE connecting circuits F35 and Q2. The Q2 circuit connects to the deck lid release solenoid.
