IMMOBILIZER SYSTEM 9W-3
SYSTEM DESCRIPTION
Gasoline Version
The Immobilizer System consists of an electronic device with integrated coil, called ‘Active Antenna’, the crypto
transponder, which is integrated in the ignition key, and the engine management system (EMS).
The Active Antenna is mounted at the ignition lock and handles the following tasks :
lTo supply the transponder with power
lTo receive the data from the EMS and transmit it to the transponder
lTo receive and demodulate the data from the transponder and transmit it to the EMS
The whole Immobilizer software, the authentication and the management of valid keys is completely managed by the
EMS.
