Hi, we are having problems with this truck. Everything works normal when the ignition switch is turned on (Lift, tilt, side shift & steering all okay) however when forward or reverse is selected and the accelerator pedal is pressed the hydraulic motor runs at high speed without touching the hydraulic levers, the truck drives perfectly fine. The motor will stay on until the accelerator pedal is released then the motor will stop. Occasionally the motor will stop after 20mins running sometimes longer. Switch it off and back on again and the same fault is back. Our customer said that he was told that it was the brake sensor?? The park brake release lever is under the floor, could the switch be at fault or are there other sensors for the brakes? Maybe nothing to do with the brakes. No codes on dash. Any help would be appreciated.
