UIM FAULT CODES / UIM ERROR CODES

UIM Control Unit – The UIM (User Interface Module) is responsible for the keyboard of the GreenStar Display 2100/2400. Using the buttons, the driver enters commands which the UIM converts into CAN BUS messages and transmits those to the VTI.

John Deere UIM fault codes / John Deere UIM diagnostic trouble codes
