Lock Motor Tailgate/Trunk Lid

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 control or if the vehicle is unlocked passively. The tailgate/trunk lid can also be opened separately using a dedicated button on the remote control.

For C70 it is also possible to unlock and open the tailgate using a lock cylinder which is located on the rear seat's left leading edge.

This lock is mechanically directly connected to the cargo compartment's locking mechanism.

The switch on the tailgate or trunk lid is directly connected to the keyless vehicle module (KVM) and to the central electronic module (CEM). This connection reduces the reaction time from the switch being pressed to the trunk lid or tailgate opening. 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 key. If an authorized 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 (3/78) is directly connected to the central electronic module (CEM).
