check the mechanical linkage to the pallet grab release and make sure there are no electrical harness's near it. If it is consistant every time you press the pallet grab release then check and see if that linkage is making contact with any wires. It may have rubbed one and every time it touches when you press the pedal to release it triggers the code.
