Circuit/System Description
WARNING: This page is about a different car, the 2013 Chevrolet Trax and 2013 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
The object sensors are 3-wire sensors that are used to determine the distance between the vehicle and an object of interest. The parking assist control module supplies 8 V to the object sensors via the object sensor supply voltage circuit and provides ground via the object sensor low reference circuit. The parking assist control module triggers the sensors in a sequential loop. After each sensor transmits, the parking assist control module uses the sensor echo received through the object sensor signal circuit to calculate the distance and position of an object.
