John Deere error UIC codes
This diagnostic trouble code (DTC) UIC 000639.12 is generated when the control unit receives too many incorrect CAN BUS messages or when it detects a general problem in the connection to the power train CAN BUS.
- John Deere error UIC codes
This diagnostic trouble code (DTC) UIC 000629.12 is generated when the control unit internally detects that too much time has elapsed (watchdog timer). This indicates that the control unit has taken longer than expected to complete its tasks, potentially due to an internal fault or processing error.

This diagnostic trouble code (DTC) UIC 000628.02 is triggered when the control unit detects an internal problem during initialization (control unit boot sequence after the ignition is switched ON). This indicates a potential issue within the control unit’s hardware or software.

This diagnostic trouble code (DTC) UIC 000606.16 is triggered when the control unit detects that the engine speed is too high. This condition is identified as excessive speed when there is no weight pushing from behind to account for it. It serves as an informational alert to reduce the travel speed to avoid potential damage…

This diagnostic trouble code (DTC) UIC 000598.31 is generated if the switch position of clutch pedal switch S72 (transmitted as a CAN message by the TCU) does not match the position of the clutch pedal (ascertained via the signal from clutch pedal potentiometer B65).
- John Deere error UIC codes
This diagnostic trouble code (DTC) UIC 000587.31 is generated if an invalid tractor type is detected in address UIC036 during initialization (booting the control unit after ignition ON). This indicates that the UIC has not been programmed properly or has not been programmed at all.

This diagnostic trouble code (DTC) UIC 000237.31 is generated when the vehicle identification number (VIN) from other control units is not received or is incorrectly received. All active VIN participants must send the programmed VIN to the UIC at regular intervals.
- John Deere error UIC codes
This diagnostic trouble code (DTC) UIC 000191.19 is generated if the Transmission Control Unit (TCU) does not register any transmission output speed and thus cannot provide the CAN BUS with any data. A transmitted replacement value generates this diagnostic trouble code in the UIC. In its active state, this fault also generates a diagnostic trouble…

This diagnostic trouble code (DTC) UIC 000091.04 is generated when the control unit measures a voltage of less than 0.5 volts at the signal input from channel 1 of the accelerator pedal potentiometer (B79, lead 6066). This indicates a problem at the signal lead or an issue with the potentiometer supply voltage.
