Circuit/System Description
WARNING: This page is about a different car, the 2010 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
The object alarm module directly controls the parking assist indicators located in the rear parking assist display. The rear parking assist display consists of two amber and one red LED that indicate the distance of an object from the rear bumper. As objects become progressively closer to the bumper, the object alarm module will illuminate the LEDs in a sequence: one amber LED, both amber LEDs, and lastly, both amber LEDs and the red LED. The LEDs are supplied voltage by the object alarm module. Each LED is also discretely controlled by the object alarm module.
