  • FORCED DOOR LOCK CONTROL


    1. The forced door lock control prevents the vehicle from being tampered with. Immediately after a door is unlocked (alarm starts), all doors are forced to lock by a forced door lock signal.


      1. Conditions that force the doors to lock:


        • The theft deterrent system is in the alarm sounding state of active arming mode.

        • Any door is unlocked.

  • SECURITY INDICATOR OUTPUT


    1. The certification ECU (smart key ECU assembly) outputs a signal to turn on the security indicator light according to the state of the theft deterrent system. However, some of the actual lighting conditions of the security indicator light are different from the output signals of the certification ECU (smart key ECU assembly).

      Output
      State of Theft Deterrent System Security Indicator
      Output Signal from Certification ECU (Smart Key ECU Assembly) Actual Lighting Condition
      Disarmed state (1), (2) OFF

      OFF (Immobiliser system unset)

      BLINKING (Immobiliser system set)
      Arming preparation state ON ON
      Armed state OFF BLINKING
      Alarm sounding state ON ON
      Blinking Cycle
      Time Security Indicator
      0.1 sec. ON
      1.8 sec. OFF

      Tech Tips

      When the engine immobiliser system is set, the security indicator light blinks during both the disarmed state and armed state, due to output signals from the engine immobiliser system.
