Control Module

The keyless vehicle module (KVM) is located behind the right-hand wheel arch in the cargo compartment. The control module controls and monitors the keyless entry system. The keyless vehicle module (KVM) uses the external and internal antennas to communicate with the remote key and to control the quick locks in the doors.

The keyless vehicle module (KVM) activates the internal or external antennas depending on the input signals and commands it receives. The control module also checks the identity of the remote key.

The keyless vehicle module (KVM) is part of the immobilizer system. It works with the central electronic module (CEM) to check remote key identities.

The keyless vehicle module (KVM) must be programmed with various codes before it can function in the system. For further information, see: DOWNLOADING SOFTWARE AND REPLACING THE CONTROL MODULE 

The two control modules communicate over the LS-CAN.

The keyless vehicle module (KVM) contains 4 power stages. The control module uses these relays to select the antennas to be activated. See the table below:

Activated power stage	Active antenna or antenna group
1	Rear left antenna in door handle
2	Rear right antenna in door handle
3	Antenna in passenger compartment 1 Antenna in passenger compartment 2 Internal antenna in cargo compartment
4	Antenna in luggage compartment

Keyless vehicle module (KVM) is 30-supplied via the Central electronic module (CEM) and grounded in the body. The Keyless vehicle module (KVM) is always supplied with power as long as the vehicle is powered.
