This system is designed to be upgraded by featuring an optional glass break sensor.

All initial setting are performed in active mode. It can be switched to passive mode by specified operation. (See step 3. CHANGING METHOD OF PASSIVE MODE)

NOTE:
There are 4 conditions in this system which are disarmed state, arming preparation, armed state and alarm sounding.
1. Disarmed state
  - When the alarming function does not operate.
  - When theft deterrent function is not performed.
2. Arming preparation
  - Time until transferring to armed state.
  - Theft deterrent function is not performed.
3. Armed state
  When theft deterrent function is possible.
4. Alarm sounding:
  In this condition, once theft is detected, it is informed using light and sound to people around the vehicle.
  
  Refer to Fig 1 for alarming method or time.

Indicator light output:

INDICATOR LIGHT OUTPUT

Condition	Indicator light
Disarmed state	OFF
Arming preparation	ON
Armed state	OFF
Alarm sounding	ON

NOTE:

Even in disarmed state, the indicator light flashes. (Due to the signal output from immobilizer system). The indicator always flashes receiving the signal from the immobilizer system at any time in the armed state.

Flashing frequency:

0.2 seconds (ON)

1.8 seconds (OFF)

Answer back:

The hazard lights flash as answer back under the following conditions.

When the system is set. When arming preparation is set from disarmed state using the wireless door lock, the hazard lights flush once.
When the system is released. When disarmed state is set from either arming preparation, armed state or alarm sounding using the wireless door lock, the hazard lights flush twice.

PASSIVE ARMING MODE

This mode can be switched according to the specified operation.
All initially set modes (when shipped from factory) are active mode. (No passive mode)
