OUTLINE OF THEFT DETERRENT SYSTEM
  1. The theft deterrent system can be set/cancelled by locking/unlocking the doors using the following operation:
    1. Wireless lock operation

ALARM MEMORY FUNCTION

  1. If the alarm is set off (tampering is detected) while the theft deterrent system is armed, it will be stored by the alarm memory function. Whenever the theft deterrent system is cancelled, the alarm memory function causes the taillights to light up for 2 seconds in order to inform you that the alarm has been set off.

    1. Conditions that cause the taillights to light up for 2 seconds:
      The theft deterrent system has entered the alarm sounding state (tampering has been detected) at least once.

THEFT WARNING INDICATOR LIGHT ASSEMBLY OUTPUT

  1. According to the state of the theft deterrent system, the main body ECU outputs a signal to turn the theft warning indicator light assembly on. However, some of the actual lighting conditions of the theft warning indicator light assembly are different from the output signals of the main body ECU.
