SMART ENTRY AND START SYSTEM


  1. OUTLINE


    1. The smart entry and start system has the following main functions, making it a very user-friendly system.

      Function Outline
      Start Function

      The start function is operated by simply pushing the engine switch while carrying the electrical key transmitter sub-assembly. When the engine switch is pushed, the certification ECU (smart key ECU assembly) turns the ACC relay, IG1 relays and IG2 relay on or off to switch the power source.*1


      • The power source changes depending on depression of the brake pedal and the shift position.
      Engine Immobiliser The engine immobiliser function compares the ID code that is registered in the certification ECU (smart key ECU assembly)*2 or ID code box (immobiliser code ECU)*3 with the ID code of the transponder chip that is embedded in the electrical key transmitter sub-assembly.
      Steering Wheel Lock The steering wheel lock function is operated to lock and unlock the steering wheel by using a lock/unlock mechanism in the steering column assembly.
