Circuit/System Description

WARNING: This page is about a different car, the 2008 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.

The electronic suspension control (ESC) module supplies a 5-volt reference signal to each suspension position sensor. The suspension position sensors supply an voltage signal of 0.35-4.75 volts to the ESC module which represents the position between the body and the wheel. The sensors are also grounded through the ESC module.
