Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Description
The parking assist sensors are 3-wire ultrasonic sensors that are used to determine the distance between the vehicle and an object. The parking assist control module supplies a reference voltage to the parking assist sensors via the Parking Assist Sensor Reference Voltage circuit and provides ground via the low reference circuit. The parking assist control module triggers the sensors in a sequential loop. After each sensor transmits, the 6 parking assist control module uses the sensor echo received through the signal circuit to calculate the distance and position of an object.
