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 has 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
your vehicle to start the engine.

Immobilizer 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 the "ON"
position, the ECU (engine control unit) transmits
the challenge message to the immobilizer unit.
(This is to verify whether the key is valid. If the
verification fails, it transmits re-verification signals
3 times for 2 seconds. If three re-verifications fail,
it stops verification and starts re-verification after
10 seconds.) (1)
ECUOnly when the two signals are identical, it recognizes the
key as the authorized one and transmits the positive
message to the ECU. (6)
The ECU enable the engine to be started. (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, please attend on the site.
In any cases, the immobilizer system can not 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 to the vehicle equipped with the immobilizer system. ·
