Lock Motor Tailgate/Trunk Lid V70 (08-)
In practice there is no "locked" position for the lock on the tailgate/trunk lid. The difference between locked and unlocked is whether the central electronic module (CEM) will activate the lock motor or not when the switch on the tailgate/trunk lid is pressed.
The tailgate/trunk lid is "locked" and "unlocked" at the same time as other doors if an unlock command is received from the remote key. The tailgate/trunk lid can also be unlocked separately using a specific button on remote key or via switch on the light switch module (LSM).
The switch on the tailgate/trunk lid is directly connected to the central electronic module (CEM), Keyless vehicle module (KVM), and Power Operated Tailgate Module (POT) (optional equipment). If the vehicle is locked and the switch pressed in, the keyless vehicle module (KVM) activates the antenna in the bumper and begins checking for an authorized remote key. If an authorized remote key is found, the keyless vehicle module (KVM) transmits a signal to the central electronic module (CEM) to activate the lock motor in the trunk lid or tailgate. The lock motor (6/8) is directly connected to the central electronic module (CEM).
