DESCRIPTION The No. 2 ultrasonic sensor sends and receives ultrasonic waves. Based on the received wave, the sensor calculates the approximate distance value between the vehicle and the obstacle, and sends the distance value as a signal to the clearance warning ECU assembly. WIRING DIAGRAM PROCEDURE
