What is electronic engine immobilizer?

What is electronic engine immobilizer?

Prevents unauthorized use of the vehicle The electronic immobilizer secures the vehicle against theft. This is achieved by a transponder with a code in the ignition key. When the ignition is switched on, that code is read by the SMARTRA (SMARt TRAnsponder, an intelligent communications interface) using an antenna.

How does the immobilizer system work in a smartra?

The immobilizer system consists of the ECM, the SMARTRA, the lamp and ignition keys with built-in transponder. The ECM carries out the check of ignition key by special encryption algorithm, which runs in the transponder and in the ECM in parallel. Only if the results are equal the engine can be started.

What makes up the immobilizer system on a Kia?

The immobilizer system consists of the ECM, the SMARTRA, the lamp and ignition keys with built-in transponder. The ECM carries out the check of ignition key by special encryption algorithm, which runs in the transponder and in the ECM in parallel.

How does smartra communicate with engine control module?

The SMARTRA communicates to a engine control module via a dedicated communications line (called W-Line, or Immo-Line). During communication of ECM and SMARTRA the K line of ECM cannot be used for communication.

Is the smartra part of the ignition lock?

The SMARTRA unit contains an integrated inductive antenna and electronics around the ignition lock assembly. The SMARTRA does not carry out the check of validity of transponder or the calculation of encryption algorithm.

Can a smartra be used as a transponder?

The SMARTRA does not carry out the check of validity of transponder or the calculation of encryption algorithm. This device is only an advanced interface, which converts the RF data flow (radio frequency of 125 kHz) of transponder into serial communication to ECM and vice versa.
