WARNING: This page is about a different car, the 2007 Jeep Patriot and 2007 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.
When controlling the normal fluid pressure or the fluid pressure at the time of selection, the secondary pressure can be set more accurately by using the fluid pressure sensor to detect the secondary pressure and performing the feedback control.
