ENGINE IMMOBILISER SYSTEM


  1. OUTLINE


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

      Tech Tips

      When replacing the transponder key ECU or making a new ignition key, key recognition code(s) must be registered. For details of the recognition code registration procedure, refer to the Service Bulletin.
