Object Alarm Module: Notes

WARNING: This page is about a different car, the 2009 Cadillac DTS. 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 eight parking assist sensors. The object alarm module receives individual signals from each of the eight 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 appropriate parking assist indicator and send a serial data message to the radio requesting an audible alert.
