Looking at your control board pic, I would suspect issues with the printed circuit board might be the problem . I had issues with a smart wheel on a friends Diplomat and nothing made sense. All operations were erratic. Had been to three different techs over time with no success. Opened the front run bay and saw that someone had removed wiring or such from the bay and left it open to the wheel so road debris had entered the bay. Pulled the printed circuit board off the wall and the back of the board was coated with road film. Cleaned it up with dielectric spray and all issues disappeared. There must have been cross talking going on between circuits.
