Circuit/System Description

WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.

The object sensors are 3-wire ultrasonic sensors that are used to determine the distance between the vehicle and an object when parallel parking. The Advanced Parking Assist Control Module supplies 8 V to the object sensors via the 8 V reference circuit and provides ground via the low reference circuit. The Advanced Parking Assist Control Module triggers the sensors in a sequential loop. After each sensor transmits, the Advanced Parking Assist Control Module uses the sensor echo received through the signal circuit to calculate the distance and position of an object.
