Internal Antennas

There is a total of three internal antennas. The internal antennas are under the carpet between the front seats, under the carpet above the center console in front of the rear seat and in the cargo compartment. The antennas allow the keyless vehicle module (KVM) to communicate with the passive key. The keyless vehicle module (KVM) activates the internal antennas in the event of any of the following:

• a signal is received from the key-in switch when the starter button is pressed in
• a signal is received indicating that the brake pedal (automatic transmissions) or clutch pedal (manual transmissions) is pressed
• a lock command is received from the remote control
• a lock button at one of the external door handles is pressed in
• the first switch in one of the external door handles is closed
• a request to check the key from the central electronic module (CEM).

The antennas are also activated when the vehicle is locked. This is to deactivate any keys which are still in the vehicle. This is so that the vehicle cannot be passively started by any keys still in the passenger compartment. A deactivated key is activated again when the vehicle is unlocked or when any of the lock buttons on the deactivated remote control are depressed.

The keyless vehicle module (KVM) checks the internal 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).
