trouble code -31

Hello. got a Clark TMX20 sit down 36 volt forklift.
Serial #TMX250-0195-9597KF
Cuts out drive and throws a code -31. Can anyone help or have a description of the code. Is it a voltage error?
I managed to clear battery corrosion built up between frame and battery case. It worked for about a day, Dont think that may have been the cause.

The problem with this is the controller
Is you check and the wire the goes from the motor to the controller is good and no blow fuse
Replace the controller.

are the contacts clicking? These trucks are prone for drive motor brushes sticking and direction contacts wear and do not make good connection.
