Toyota 4Runner: Rear Clearance Sonar Sensor RH Circuit

Toyota 4Runner Service Manual / Audio / Visual / Telematics / Park Assist / Monitoring / Intuitive Parking Assist System / Rear Clearance Sonar Sensor RH Circuit

DESCRIPTION

The ultrasonic sensor sends and receives ultrasonic waves. Based on the received wave, the sensor calculates the approximate distance between the vehicle and the obstacle, and sends the distance value as a signal to the clearance warning ECU assembly.
