Parking Assist Control Module: Notes
WARNING: This page is about a different car, the 2010 Buick LaCrosse. However, it is still accessible from the selected car via links, so may be relevant.
The parking assist control module provides a reference voltage and a low reference to the four rear object sensors. The module receives individual signals from each of the four sensors and determines the location and distance of an object based on these inputs. When an object is detected, the module will command the object alarm module to provide an audible alert.
