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 the C70, it is also possible to unlock and open the cargo compartment using a lock cylinder, which is located under the cup holder in the center console (model year 2006 and early 2007 versions). For the C70 (late versions 2007-), the lock cylinder is located on the left-hand front edge of the rear seat.
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).
