Object Alarm Module
WARNING: This page is about a different car, the 2012 Chevrolet Cruze. However, it is still accessible from the selected car via links, so may be relevant.
The object alarm module provides an 8 V reference and a low reference to the four object alarm sensors. The object alarm 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 object alarm module will send a data message via CAN-Bus to the radio requesting an audible alert.
