      1. If the following conditions are met, the forced door lock control is operated.


        • The theft deterrent system is in the armed state.

        • Any door is unlocked.

  • SECURITY INDICATOR OUTPUT


    1. The main body ECU (driver side junction block assembly) outputs a signal to come on the security indicator, according to the state of the theft deterrent system. However, some of the actual lighting conditions of the security indicator are different from the output signals of the main body ECU (driver side junction block assembly).

      Output
      State of Theft Deterrent System Security Indicator
      Output Signal from Main Body ECU (Driver Side Junction Block Assembly) Actual Lighting Condition
      Disarmed state (1), (2) OFF

      OFF (Immobiliser system unset)

      Tech Tips

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