Circuit/System Description

WARNING: This page is about a different car, the 2008 Cadillac CTS. 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 bumpers. The object detection system will notify the driver when backing up 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 the telltale assembly 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 telltale assembly information center by the object alarm module via the telltale assembly supply voltage circuit. The telltale assembly information center indicators are controlled by the object alarm module via the indicator control circuits. The object alarm module provides the ground for the indicator control circuits.
