INTRUSION SENSOR CIRCUIT
CIRCUIT DESCRIPTION
The intrusion sensor (theft warning radar sensor) senses any moving object by using ultrasonic waves and
outputs the signals to inform the theft warning ECU of an intrusion, so that the theft deterrent system can
set off the alarm.
When the theft deterrent system is switched to the arming preparation state, the intrusion sensor is supplied
with S+B by the theft warning ECU. This causes the theft deterrent system to set off the alarm when the signal
is input from the intrusion sensor in a situation such as when the window glass is broken.

THEFT WARNING SIREN CIRCUIT
CIRCUIT DESCRIPTION
The theft warning siren has an internal battery. If any of the vehicle's battery or communication line is opened,
the theft warning siren detects it by itself and sounds. Although the theft warning siren sounds by receiving
a signal from the theft deterrent ECU usually, the theft warning siren can sound by its internal battery in case
that the vehicle's battery is opened.
The theft deterrent ECU sends an arming signal to the theft warning siren while transferring to the armed
state, and it also sends a disarming signal to the siren while transferring to the disarmed state. Besides, the
theft deterrent ECU can cause the theft warning siren to sound by sending an alarm signal in the alarm
sounding state.
