When the valet lockout in the rear compartment lid release switch is in the UNLOCK position, battery positive voltage (B+) is applied in the following ways:
| • | From the TRUNK REL fuse |
| • | Through the contacts of the rear compartment lid release relay |
| • | Through CKT 56 (BLK/WHT) to the rear compartment lid release actuator |
The rear compartment lid release actuator is grounded at all times through CKT 650 (BLK) to ground G400.
Pressing the rear compartment lid release switch provides a ground input signal to the body control module (SBM) through CKT 1576 (BLK), the switch contacts and CKT 450 (BLK). The SBM provides a message on the Class 2 serial data line to the remote function actuator (RFA) module. The RFA module in turn grounds the rear compartment lid release relay control at terminal A1. This terminal grounds CKT 1344 (LT BLU) which energizes the rear compartment lid release relay coil. The relay contacts close in order to perform the following functions:
| • | Actuate the rear compartment lid release actuator |
| • | Release the rear compartment lid. |
The rear compartment lid may be released using the keyless entry transmitter regardless of the valet lockout position. Pressing the rear compartment lid release button on the transmitter provides a signal to the remote function actuator (RFA) module. The RFA module grounds the rear compartment lid release relay control at terminal A1. This ground applied to CKT 1344 (LT BLU) actuates the rear compartment lid release relay.
