ENGINE IMMOBILISER SYSTEM GENERAL


  1. OUTLINE


    1. The engine immobiliser system compares the ID code that is registered in the transponder key ECU with the ID code of the transponder chip that is embedded in the ignition key. The system unsets if these ID codes match. Thus, the transponder key ECU and ECM communicate with each other to authorize fuel injection and ignition, enabling the engine to start.
