Thanks,
Are the two bags connected? (there are 2 separate air supply valves).
Strange, the dash button for the OR mode doesn't always respond, somtimes requiring the car to move a few yards first. In low range the button responds faster, but not always. Can't get much info from RAVE which says it should respond anytime (no range mentioned) , unless the vehicle is disarticulated. How does it know if it is disarticulated? must be reading a pressure difference in the bags. Does anyone care to explain the system to me please.
