ENGINE IMMOBILISER SYSTEM


  1. OUTLINE


    1. The engine immobiliser system compares the ID code registered in the ID Code Box (transponder key ECU) with the ID code of the transponder chip embedded in the key. The system unsets if these ID codes match. Thus, the ID Code Box (transponder key 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 (transponder key ECU) or making a new key, key recognition codes must be registered. For details, refer to the Service Bulletin.
