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.

transponder, which is integrated in the ignition key, and the Immobilizer-Control-Unit (ICU).
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 ICU and transmit it to the transponder
lto receive and demodulate the data from the transponder and transmit it to the ICU
The whole Immobilizer software, the authentication and the management of valid keys and controlling the fuel valve

IMMOBILIZER SYSTEM 9W-7
System Integration
The med 98.2 immobilizer is an anti-theft protection device allowing the start of the engine only if a specific authorization
is obtained during the start up phase. The med 98.2 will allow (prohibit) the start of the engine by driving ON (OFF) an
internal solenoid valve.
The med 98.2 is a single unit integrating the following subsystem :
la valve that allows (valve open) or blocks (valve closed) the fuel flow through the engine fuel system
la microprocessor control system to control and activate the valve during the start up of the engine, in order to
allow the start up only when a specific permission is given
the med 98.2 task is, therefore, to prevent the non authorized start up of the engine.
The functional unit includes also a basic set of electronic components whose function is to reduce its dependence on
the microprocessor control system: a part from a short temporarily period, during the start up phase, the electronics
allows the control system to excite and open the valve, but it doesn’t allow to close it.
The valve can be shut off only after the KL 15 has been deactivated.
The structure allows to obtain the highest degree of safe-operation (functionality fail-start): a failure in the
microprocessor unit cannot cause the shut-off of the valve. The main consequence of this type of failure is to prevent
the next engine start up.
As a result of the above considerations, the med 98.2 immobilizer can realize its anti-theft functionality only in conjunction
with a control device: the ICU.
The ICU, when requested, sends a coded message to med 98.2 according to a settled communication protocol. The
med 98.2 will allow the start of the engine based upon this message.
In addition to the basic anti-theft functionality, the 98.2 immobilizer provides a number of diagnostic services when it
is connected to an external test instrument (SCAN-100). Those connections are depicted in the following integration
diagram (Fig. 1), where the dashed line indicates a temporary link for diagnostic purposes, and the shaded area the
med 98.2 system’s physical boundaries:
