Circuit Description

The immobilizer control system is an anti-theft device

which enables the starting to be possible only when the

mechanical and wireless secret codes, memorized in

the Engine Control Module, and the Immobilizer Control

Module(Except Diesel)/SMATRA (Diesel) , are aligned

simultaneously.

The transponder (bulit-in the ignition key) sends unique

frequency secret code signals to the ICM/SMATRA

through Antenna coils. The ICM/SMATRA compares

the received code signals with memorized code. When

the codes are aligned, the ICM/SMATRA sends signals

to the ECM.
