When I just drove my Fleetwood out of the dealer parking lot, the steering scared me. It was too lose. Changing lanes was kind of stressful as well. I ran onboard diagnostics and got 128 which is VES related. Never fixed the problem, just got used to it. Rarely I will have limited effort steering at low speeds.
By the way, any malfunction of VES will turn the system to full effort assist. so disconnecting anything is not going to help in your case either.
