A Code 40-13 occurs when the Bobcat Controller detects that the Right Joystick Grip is not communicating with the Right Joystick Base. The auxiliaries will be disabled with a Code 40-13 present. Possible Cause: Wire harness between the Right Joystick Grip and Base. Moisture, corrosion, or pushed back pins in the Right Joystick assembly. If the code is intermittent and not on at the time of testing, the cause of the code may not be found at this time. Probable causes may include: loose connections, corrosion, pushed back pins, the controller, the wire harness or a combination of these problems. Troubleshooting Procedure: Note: Key switch / (run/enter) must be Off when connectors are disconnected or connected. 1 Check the wires and connectors between the Right Joystick Base and Grip. Are the wires and connectors in OK? Go to Step 2. Repair or replace Right Joystick. 2 Switch the Right Joystick Grip with the Left Joystick Grip. Does the code change to 39-13 "Left Joystick Grip No Communication"? Replace Right Joystick Grip. Replace Right Joystick Base.
