Circuit Description
WARNING: This page is about a different car, the 2011 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
The air suspension pressure sensor sends a voltage signal to the air suspension control module that corresponds to a pressure within the range of 30-180 psi. The air suspension control module also uses this signal to verify that the proper amount of pressure is achieved in the air dryer within 23 seconds prior to opening of the inlet valves for inflation of the air springs.
