Unlocking Using Trunk Lid Request Switch: Notes

The method for unlocking trunk lid using trunk lid request switch is as follows.

1. Push trunk lid request switch (1) in trunk lid.
2. Keyless start control module (2) activates mid inside antenna (3) and rear inside antenna (4) to transmit within the vehicle compartment and trunk room.
3. When keyless start control module determines that remote controller (5) is not in vehicle compartment and trunk room, it activates rear outside antenna (6) to send request signal to remote controller.
4. Remote controller receives request signal and then sends ID code to keyless start control module via keyless entry/TPMS receiver (7).
5. Keyless start control module compares ID code sent from remote controller with ID code registered in keyless start control module. If ID codes match, keyless start control module outputs trunk lid opener request signal to BCM (8) through CAN communication.
6. BCM activates trunk lid opener actuator (9).
