Annex No.5 Functional Description SIEMENS VDO Automotive AG SV C BC P2 RF TG FCC ID:KR55WK48089 IC:267T-5WK48089 Functional Description / User Manual of the Siemens VDO Keyless Vehicle Module type 5WK4 8079 5WK4 8089 File: D:\Postzula\Kunden\Mb\W221\FunctionalDiscription_W221.doc Page 1 of 1 SIEMENS VDO Automotive AG SV C BC P2 RF TG FCC ID:KR55WK48089 IC:267T-5WK48089 General functional description The immobilizer system is equipment which enables comfortable operation of the vehicle. To be able to operate the vehicle the driver only has to take the key with him. The vehicle communicates with the key inductively via ferrite- antennas which are located in the front doors, in the interior of the car and in the bumper. These ferrite antennas are driven by inductance with a frequency of 125 kHz. By damping the body sheet-metal of the car, the system's range is kept in defined limits. The range of the interior antennas of the vehicle is the interior of the car only. This enables the locating of the key. The door handles and the trunk lid have been equipped with contacts for the functions "locking" and "unlocking" the vehicle. Woken up by pulling a door handle the immobilizer sends a challenge 125 kHz via the corresponding inductive door antenna to the key. The data transmitted in the process activate the key. The key sends a code to the radio receiver on the control unit via radio frequency transmission. The control unit transmits the data to the vehicle's "electronic ignition starter switch (EZS)”. If this code is assessed as valid in the EZS, the vehicle will be unlocked. If a lock command is send to the control module while the vehicle is unlocked, the EZS and the key interchange a code via the control module and the antennas. If the key is in the exterior area and the code is valid, the vehicle will be locked. If it is intended to start the engine of a vehicle, this requires actuation of a start key. The interior inductive antennas are activated. This is to ensure that the key is inside the vehicle. If the valid code is emitted by the key, the engine will start. If the code is invalid, the engine will not start.

To activate the system, sensors or push-buttons are located in the doors, in the trunk lid and in the interior. Interaction with the vehicle is effected via the radio receiver in the control module, which receives the messages from the key and transmits them via the vehicle's CAN bus to the EZS.
