THEFT DETERRENT SYSTEM > ON-VEHICLE INSPECTION |
| 1. OUTLINE OF THEFT DETERRENT SYSTEM |
When the theft deterrent system detects that the vehicle is being tampered with, the system sets off the alarm, causing the horns to sound and the lights to light up or blink in order to alert people around the vehicle to the theft.
Each mode has 4 states; a disarmed state, an arming preparation state, an armed state and an alarm sounding state.
Disarmed state:
Arming preparation state:
Armed state:
Alarm sounding state:
| Alarm Method | Headlight | Blinking (Except for Europe) |
| Taillight | Blinking (Except for Europe) | |
| Hazard Warning Light | Blinking | |
| Interior Light | Illuminating | |
| Vehicle Horn | Sounding (approx. 0.4 second cycles) | |
| Theft Warning Siren | Sounding | |
| Alarm Time | Approx. 30 sec. (Maximum 10 times (Europe only)) | |
| 2. ACTIVE ARMING MODE |
Active arming mode

| Condition | Item |
| Condition (1) | (No key in ignition key cylinder)
|
| Condition (2) |
|
| Condition (3) |
|
| Condition (4) |
|
| Condition (5) |
|
| Condition (6) |
|
| 3. FORCED DOOR LOCK CONTROL |
The forced door lock control prevents the vehicle from being tampered with. Immediately after a door is unlocked (alarm starts), the door is forced to lock by a forced door lock signal.
Conditions that force the doors to lock:
No key is in the ignition key cylinder and both of the following conditions are met.
| 4. SECURITY INDICATOR OUTPUT |
The multiplex network body ECU outputs a signal to light up 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 multiplex network body ECU.
| State of Theft Deterrent System | Security Indicator | |
| Output Signals from Body ECU | Actual Lighting Condition | |
| Disarmed state (1), (2) | OFF | OFF (Immobilizer system unset) BLINKING (Immobilizer system set) |
| Arming preparation state | ON | ON |
| Armed state | OFF | BLINKING |
| Alarm sounding state | ON | ON |
| Time | Security Indicator |
| 0.2 sec. | ON |
| 1.8 sec. | OFF |
| 5. INTRUSION (THEFT WARNING) SENSOR (FOR EUROPE) |
An intrusion sensor is provided in the front interior light located in the front of the vehicle interior.
Intrusion sensor consists of intrusion sensor OFF switch, 4 microphone (transmitter and receiver) and ultrasonic sensor (amplifier and CPU). In this sensor, the ultrasonic waves are output by the transmitter microphone and input by the receiver microphone. The CPU determines that an intrusion has taken place by detecting the changes in the ultrasonic waves that have been amplified by the amplifier.

The theft deterrent ECU activates the intrusion sensor when the system changes from the disarmed state to the armed preparation state. If an intrusion detection signal is input from the intrusion sensor during the armed state, the ECU changes to the alarm state in order to output an alarm.
When the system is in the disarmed state, the function of the intrusion sensor can be disabled by pressing the intrusion sensor OFF switch. If the system changes from this state to the armed preparation state, the intrusion sensor will not activate.
| 6. THEFT WARNING (SELF-POWER) SIREN |
The theft warning siren has an internal battery. If any of the vehicle's battery or communication lines are opened, the theft warning siren detects it by itself and sounds. Although the theft warning siren usually sounds by receiving a signal from the multiplex network body ECU, the theft warning siren can sound using its internal battery in case that the circuit of the vehicle's battery is opened.
The multiplex network body ECU sends an arming signal to the theft warning siren while switching to the armed state, as well as sending a disarming signal to the siren while switching to the disarmed state. Additionally, the multiplex network body ECU can sound the theft warning siren by sending an alarm signal in the alarm sounding state.
