Parking and Back-Up Sensor System Description - Components

Parking and Back-Up Sensor Switch 

Input to the parking and back-up sensor control unit is performed by operating the parking and back-up sensor switch. The parking and back-up sensor indicator is activated by the parking and back-up sensor control unit.

Parking and Back-Up Sensors 

The parking and back-up sensors emit ultrasonic waves, which are reflected by obstacles and then detected by the sensors. The detected ultrasonic waves are converted to digital signals after amplification, and are then transmitted to the parking and back-up sensor control unit.
