Object Alarm Module: Notes
WARNING: This page is about a different car, the 2009 Saturn Outlook, 2009 GMC Acadia, 2009 Chevrolet Traverse, and 2009 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
The object alarm module provides an 8-volt reference and a low reference to the four rear parking assist 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 illuminate the appropriate LED on the parking assist indicator and send a serial data message to the radio requesting an audible alert.
