Title: PARK ASSIST / MONITORING: INTUITIVE PARKING ASSIST SYSTEM: Back Sonar Sensor RH Circuit; 2015
MY Tundra [08/2014 - ]
Back Sonar Sensor RH Circuit
DESCRIPTION
The No. 3 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.
