system functions no problem all four levels, especially now that i finally got it all calibrated thanks to everyone's help. but, it doesn't adjust based on speed anymore, over 75 it used to drop to level one, then raise back up after exiting the highway. it is not in the "manual" mode but needs to be told like it is?? any ideas where to start, no warning lights or fault codes either-
thanks!!
