Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
External Antennas
The outer antennas are located in the door handles on the rear doors and in the luggage compartment.
The antennas make it possible for the Keyless vehicle module (KVM) to communicate using a remote key outside the vehicle.
The keyless vehicle module (KVM) activates one or some of the antennas when the vehicle is locked and:
- the system receives a wake up signal from one of the unlocking switches in the door handles (unlocking)
- the system receives a wake-up signal from the switch on the tailgate (unlocking)
- one of the outer lock buttons is pressed in (locking)
- an unlocking command is transmitted from the Central electronic module (CEM).
The output of the antennas is adjusted during installation. This is so that there must be a valid remote key within a radius of approximately 1.5 meters from an active antenna for the system to function correctly.
The keyless vehicle module (KVM) checks the external antennas every operating cycle if the vehicle speed is in excess of 20 km/h (12 mph).
The antennas are powered by the keyless vehicle module (KVM).
