Rear Object Sensor Control Module: Notes
WARNING: This page is about a different car, the 2011 GMC Sierra, 2011 GMC Cab & Chassis Sierra, 2011 Chevrolet Silverado, and 2011 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
The rear object sensor control module provides an 8 V reference and a low reference to the four object alarm sensors. The rear object sensor 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 rear object sensor control module will send a serial data message to the radio requesting an audible alert.
