2 Product concept The whole immobilizer function is accomplished by the mutual authentication between key and BCM while the active antenna is playing a role of charging transponder in key and data modulation (demodulation) in the communication path. The typical immobilizer system with active antenna can be referenced as below: Only active antenna is covered by this technical specification
2.1
Functionality
• Magnetic field generation: The active antenna contains base station for driven antenna coil which generates the LF field for charging transponder as well as carrying the modulated data. • Serial communication with BCM: The active antenna is connected to BCM via synchronous serial link. LF communication data is converted to baseband signals by active antenna and transmitted in half-duplex mode between transponder and BCM on this interface. 2.2 HW concept PCBA is reuse DFL step 8 PCBA. Simple HW block diagram can be found as below:

The active antenna contains the ABIC1 immobilizer base station IC, a ceramic resonator for clock generation, and a voltage regulator for stabilization of power input. It needs to be connected to the BCM for the communication function as well as to battery supply and ground.
2.3 Mechanical concept 2.3.1 IMMO overview The LF antenna is integrated into the housing: • One housing with integrated LF antenna, connector and PCB fixture, • One cover ring, in front side of the antenna coil.
