Immobilizer System

DESCRIPTION
The vehicle is equipped with an immobilizer system that will disable the vehicle unless the proper ignition key is used.This system consists of a transponder located in the ignition key, an immobilizer antenna unit (SMARTRA), an indicator light and the ECM/PCM.

The SMARTRA unit contains an integrated inductive antenna and electronics around the lock assembly. The SMARTRA communicates to the ECM (Engine Control Module) via a dedicated communications line.

Since the vehicle engine management system is able to control engine mobilization, it is the most suitable unit to control the SMARTRA.




When the key is inserted in the ignition and turned to the ON position, the immobilizer antenna unit sends power to the transponder in the ignition key. The transponder then sends a coded signal back through the immobilizer antenna unit to the ECM/PCM.
1. The immobilizer system can store up to four key codes.
2. If it is necessary to rewrite the ECM/PCM to learn a new key, the dealer needs the customer's vehicle, all its master keys and the Hi-scan(pro) equipped with an immobilizer program card. Any key that is not learned during rewriting will no longer start the engine.
3. If the customer has lost his key, and cannot start the engine, contact Kia motor service station.
4. If the proper key has been used, the ECM/PCM will energize the fuel supply system. The immobilizer indicator light in the gauge assembly will simultaneously come on for about 2 seconds, then go off, indicating that the immobilizer antenna unit has recognized the code sent by the transponder.
5. If the wrong key has been used and the code was not received or recognized by the ECM/PCM the indicator light will come on for about 2 seconds, then it will continue blinking until the ignition switch is turned OFF.
