THEFT DETERRENT DETAILS

FUNCTION

1. The theft deterrent system has the following functioris:

   Function	Outline
   Alarm	When the theft deterrent system enters the alarm state, the warning items (hazard warning lights and security horn or self-power siren) are operated for approximately 27.5 seconds.
   Security Indicator	When the state of the theft deterrent system enters the armed preparation or alarm state, the security indicator light is illuminated to inform the user. This indicator is also the engine immobiliser indicator, it blinks when the engine immobiliser is in an engaged state.
   Forced Door Lock	The main body ECU (multiplex network body ECU) transmits a door lock signal when all of the following conditions are satisfied. The theft deterrent system is in the alarm state (except in the situation where a door has been unlocked with the mechanical key). Any door has been unlocked The function stops when one of the following conditions is met. All doors are locked. The warning ends. Either front door is unlocked using the mechanical key.

CONSTRUCTION

1. Intrusion Sensor

   
   

   1. An intrusion sensor is provided in the map light assembly.

   2. If the intrusion sensor detects an inappropriate entry into the vehicle interior by an intruder (including intrusions made by breaking window glass), a warning signal is sent to the main body ECU (multiplex network body ECU).

   3. The intrusion sensor operation can be suspended for a short period of time by pressing the intrusion sensor cancel switch, provided on the map light assembly, before the theft deterrent system is set.

   4. The intrusion sensor, which is linked to the auto alarm system, sets automatically when the system transfers to the armed state (and the setting of the auto alarm is completed).

   5. When the intrusion sensor detects a moving object in the vehicle interior, the system transfers to the alarm state. Then, the system sounds the horn intermittently and blinks the hazard warning lights for approximately 27.5 seconds and performs a forced locking operation.

      Tech Tips

      
      

      • Radio waves are used to detect intrusion. Radio waves do not penetrate steel or glass. When any of the side windows is left open, radio waves may escape. This may result in the detection of people in the surroundings, leaves or insects entering the vehicle, strong wind or other radio wave sources in the environment when the vehicle is parked with the side windows open.

      • When parking the vehicle with the side windows open for ventilation, turn off the intrusion sensor using the off switch.

2. Glass Breakage Sensor

   
   

   1. By sending signals through the connected sensor strips on the back door glass and rear quarter glass, the glass breakage sensor can detect breakage of those glasses.

   2. The glass breakage sensors are linked to the theft deterrent system, and they will automatically be set when the system enters the armed state. During the armed state, when the glass breakage sensor detects an open circuit of the print patterns on the back door glass and rear quarter glass, it transmits a signal indicating glass breakage to the main body ECU (multiplex network body ECU), and the system enters the alarm state.

3. Self-power Siren (Theft Warning Siren Assembly)

   
   

   1. During a normal operation, this siren sounds an alarm in accordance with the operation signal from the main body ECU (multiplex network body ECU). Because this siren has an internal battery, it can independently sound an alarm even if the vehicle's battery terminals are disconnected or if the wiring harnesses that are related to the system are cut.
