Circuit/System Description
WARNING: This page is about a different car, the 2017 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
The suspension control module supplies a 5 V reference signal to each suspension position sensor. The suspension position sensors supply a signal of 0.3-4.7 V to the suspension control module which represents the position between the body and the wheel. The sensors are also grounded through the suspension control module.
