Today while driving a "suspension malfunction 30 MPH, vehicle will lower" came in the dash and it dropped all the way down. Code U0155-87. Per GAP tool it says LCD Gauge communication lost- bus signal/message failure-missing a message(2B). I deleted the code and as soon as I speed up the same issue came back. If anyone has idea on how to proceed before I go and change to coil springs and be done. Thanks
