ENGINE IMMOBILISER SYSTEM GENERAL


  1. OUTLINE


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

      Tech Tips

      When replacing the ID code box (immobiliser code ECU) or making a new key, key recognition code(s) must be registered. For details, refer to the Service Bulletin for the ENGINE IMMOBILISER SYSTEM (KEY REGISTRATION).
