External Antennas
The external antennas are mounted in the door handles (C30/C70 front doors, S40/V50 rear doors) and in the rear bumper. The antennas make it possible for Keyless vehicle module (KVM) to communicate with a key outside the vehicle.
The keyless vehicle module (KVM) activates one or more antennas when:
- the system receives a wake up signal from one of the unlocking switches in the door handles
- the system receives a wake-up signal from the switch on the tailgate
- one of the outer lock buttons is pressed in.
The keyless vehicle module (KVM) checks the external antennas every 5th operating cycle if the vehicle speed is in excess of 20 km/h.
The antennas are powered by the keyless vehicle module (KVM).
