Operation

1.When the theft-deterrent system is stand-by 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 BCM.
