Operation

1. When the theft-deterrent system is standby mode, the intruder sensor outputs ultrasonic waves in the passenger compartment. The intruder sensor detects differences in the ultrasonic waves (reflected waves) that are output and bounced off a target object.

2. When a difference in reflected waves occurs by movement in the vehicle (intruder), the CPU calculates the level of difference.

3. If the differences meet certain criteria, the intruder sensor sends a detection signal to the body control module (BCM).
