2. OVERVIEW
The Immobilizer System provides an additional theft deterrent to the vehicle in which it is installed and
prevents it from being started by unauthorized persons. The transponder integrated in the key and the
engine control unit have the same code. When the ignition key with the integrated transponder is
turned to the ON position, the ECU (Engine Control Unit) checks the crypto code of the key and, if
correct, allows the vehicle to start the engine. If the verification has been failed, the engine cannot be
started and the immobilizer warning lamp blinks.

ECU
Immobilizer Indicator and Warning Lamp ▶
This indicator comes on when the ignition
key is communicating with the engine control
unit (during engine starting) and goes out
after starting the engine.
When turning the ignition key to ON position, the
ECU transmits the challenge message to the
immobilizer unit to verify whether the key is valid. (1)
Only when the two signals are identical, it
recognizes the key as the authorized one and
transmits the positive message to the ECU.
The ECU allows the engine to be started. (6)
(7)
Do not drop or shock to the transponder in the key as it may be damaged.
With a damaged transponder, the engine cannot be started.
When you erase the code or register an extra key, let the owner attend on the site.
In any case, the immobilizer system cannot be removed from the vehicle. If you attempt to
remove it and damage the system, starting will be impossible, so never attempt to remove,
damage or modify it.
The remote engine starter cannot be installed on the vehicle equipped with the immobilizer
system. -
