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
NOTE:This page only indicates the meaning of the fault codes. For complete troubleshooting information, see the technical manuals.
UIM 000168.03 (UIM 168.03)— Supply Voltage (ELX) Too High
This diagnostic trouble code is triggered if system voltage (ELX) is above 15.5 volts for longer than 5 seconds.
UIM 000168.04 (UIM 168.04)— Supply Voltage (ELX) Too Low
This diagnostic trouble code is triggered if system voltage (ELX) is less than 10.0 volts for longer than 5 seconds.
UIM 000628.02 (UIM 628.02)— Control Unit Internal Fault
If a fault occurs when the internal module (EEPROM) intervenes, this diagnostic trouble code is triggered.
