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 an 8 V reference and a low reference to the four rear parking assist sensors. The parking assist control 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 parking assist control module will illuminate the appropriate LED on the parking assist indicator and send a serial data message to the radio requesting an audible alert.
