There are fuses for the smart wheel. Rarely do they simply go blank unless it's fuse related. If they begin to fail, one side or the other fails or begins to "stick" first. The fuse(s) may be in the front bay under the driver's seat or yours could be in the engine compartment fuse bay. I'm surprised the tech you had look at it did not know about the reset so he may not know about the fuses.
Also, look for any 'hidden' fuses. Open your front wiring bay and look on the BACKSIDE of that door. There should be a sticker there telling which devices have hidden fuses and their location.
