Siemens VDO Automotive AG SV C ERFile:S:\Postzula\Dwmc\Func_Immo_Dwmc.doc Page 2 of 4General description of the immobilizerThe described system is a transponder-based immobilizer for an automotivevehicle.The immobilizer system consists of :- up to 4 ignition keys with transponder integrated in the key head- the antenna for energizing and communication with the transponderwith its integrated electronic modulator/demodulator driver- the external status indicator (LED) for displaying the immobilizer statusThe purpose of the immobilizer system is to provide an additional anti-theft-system which is installed in the vehicle. Checking of user authorization isdone by use of an ignition key whose head integrates a crypto-transponder.In case of a blocked immobilizer system (unauthorized key), the ECM controlunit locks the engine control by cutting off the ignition circuit and the injectorscircuit.The antenna is a coil allowing to create the electromagnetic field ncessary fortransponder operation. The antenna generates an electromagnetic field usinga frequency of 134.2 kHz. This field induces energy into the transponder byway of its resonant circuit.The external status indicator (LED) displays the immobilizer status, and hasan additional deterrence function.Variant:Siemens type designation frequency5WY 8301 134.2 kHz Immobilizer antennaFCC ID:KR55WY8301
