Parking Assist Control Module
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 parking assist control module provides a voltage reference and a low reference to the two object alarm sensors located in the front and rear bumpers on the left and right side of the vehicle from speeds of 10 km/h (6.2 MPH) up to 140 km/h (87 MPH). The parking assist control module receives individual signals from each of the four sensors and determines the location and distance of a vehicle in the side blind spot based on these inputs. When an object is detected in the side blind zone, the parking assist control module will illuminate the visual indicator on the accordant side rear view mirror.
