IMMOBILIZER SYSTEMDESCRIPTION:

Immobilizer system is designed to prevent vehicle

theft by electronically disabling the engine starting

system. The engine can be started only with

vehicle’s original immobilizer ignition key which

has an electronic identification programmed

code. The electronic key communicates the

identification code to Immobilizer control unit (ICU)

when the key is turned to the “Ignition ON” position.

Immobilizer comes with two Electronic keys (E-

key), (maximum 6 E-keys are possible). The

immobilizer used is based on CAN system.

CAUTION:

As CAN communication protocol doesn’t work

beyond 18V, vehicle will not start under “Jump

Start with voltage > 18 V” conditions.
