ECM (Engine Control Module)
- SMARTRA type immobilizer
The ECM carries out a check of the ignition key using a special encryption algorithm, which is programmed into the transponder as well as the ECM simultaneously. Only if the results are equal, the engine can be started. The data of all transponders, which are valid for the vehicle, are stored in the ECM.
- Shinchang type immobilizer
In the Ignition ON position, the engine ECM receives information from the ICM and permits injection to take place.
