[QUOTE="Raptor430, post: 1500883, member: 39946"] We had a customer who was experiencing this same issue, I rode in his truck and it was pretty bumpy. From what I have read when the live valve system has a fault it will set all 4 shocks into full stiff mode. This truck felt like it was in full stiff mode, even the smallest bump was not absorbed but transmitted through the truck. We took the vehicle in and hooked it up to our IDS (Ford Integrated Diagnostic System). The IDS allows you to choose from a table of sensors or inputs the Live Valve system has. The ride height sensors were giving out different readings when they should have been similar. We tried initialized the two sensors and were unsuccessful in completing the procedure. We decided to reflash the live valve module, and then initialize the two ride height sensors. This step asks you to have the truck completely empty of any additional weight, (no driver), door closed, it even asks you how much fuel the truck has in it. Once we completed this procedure we took it for a road test and it was immediately noticeable. The truck was absorbing the little impacts and felt much smoother. I took the customer for a road test and he was happy with the results, so much so that I have not heard back from him since. [/QUOTE]
