EV100 Controller, 1A close to fast and speed jumps

I have this problem for quite a moment tbut did nothing about it. The speed control works correctly sometime but the other time, the contactor 1A close to soon and cause the truck to jump. However, there is no code and the controller never shut down. I tried to adjust function #3 and it seems to cured for me but the operator came back later in the day saying nothing has changed. My question is, how the logic card knows the truck is almost full speed and decide to close 1A? Any idea what could cause this phenomena? the battery is good. Thanks in advance. The truck is a Yale ERC065RFN... and the oscillator card is IC3645LXCD1

Sounds like the accelerator potentiometer has begun to fail or the pedal sensor, which ever the lift has. Not familiar with the yale numbers. That can give you erratic function from the acceleration side without setting codes.
