LaserWash 4000 Help

Just replaced and calibrated VT. Wash arm is travelling too far across rear of vehicle and when it rotates to up pass side, it becomes stuck on the T-Bar so that when it reaches the front of the vehicle it faults for arch rotate failure. What should I be looking at??
TIA.

Check picket count prox switch to see if pulses are coming into JO box. And you could move your right limit flag inward a bit. If those are ok, then it could be the right ultrasonic is bad.
