Circuit/System Description

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

When the ignition is turned ON, the object alarm detection system performs tests to diagnose critical malfunctions within itself. When the object alarm detection system has completed the power-up mode, the object detection module will establish communication with the body control module (BCM). During the power-up mode the object detection module will check itself for a valid calibration data set, if no valid calibration set is found the object detection module will set a DTC and command the red parking indicator ON.
