Circuit/System Description

WARNING: This page is about a different car, the 2007 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.

The object alarm system senses how close the vehicle is to an object. The distance is determined by the 4 ultrasonic sensors located in the rear and front (if equipped) bumpers. The object detection system will notify the driver when backing up or moving forward while parking at speeds less than 8 km/h (5 mph). The object alarm system makes parking easier and helps avoid colliding with objects such as parked vehicles. The object alarm system will use front and rear information center indicators and the radio speakers to notify the driver when an object is within the object alarm system field of view. Power is provided to the information center telltale assembly via the BCM for the front system and for the rear system power is provided by the object alarm module. The information center indicator(s) is controlled by the object alarm module via the indicator control circuits. The object alarm module provides the ground for the indicator control circuits.
