Drove unit normal all conditions to the mall for half hour shopping, when I came out I noticed that the vehicle had completely deflated to the rest stops. Upon inserting key and starting unit the Red Vehicle Suspention lite was on and info says Special Programs unavailable. Tried several button resets to no avail. Drove home about 8 Kms slow under 30 and still did not rise to any height. I don’t hear compressor starting either, but that could be because System Fault. Put my scanner on but won’t read those codes?
