Kubota Tractor Error Codes – List of Fault / DTC Codes

Kubota tractor error codes are alphanumeric codes generated by the onboard diagnostic system of Kubota tractors. These codes are designed to indicate specific issues or malfunctions within the tractor’s systems. When a fault is detected, the diagnostic system assigns a unique code to identify the problem. These error codes can vary depending on the specific model and configuration of the tractor, as well as the type of onboard diagnostic system installed.

Common types of errors include engine-related issues, transmission problems, hydraulic system malfunctions, electrical faults, and sensor failures. When an error code is displayed, it is essential to consult the tractor’s operator manual or contact a certified Kubota technician to diagnose and resolve the issue effectively.

Can I Reset my Kubota Tractor Error Myself?

Yes, you can reset your Kubota tractor error codes yourself by following specific procedures outlined for your tractor model. The process may involve pressing buttons in a specific pattern, troubleshooting through the menu, or following a set of instructions provided in the tractor’s manual. While it is possible to reset the error codes independently, it is always recommended to consult with a professional Kubota customer service team, especially if you encounter persistent issues or are unsure about the process.

Resetting Kubota tractor errors may vary depending on the specific error code and the model of the tractor. In some cases, simple issues can be resolved by turning off the tractor, waiting for a few minutes, and then restarting it. However, for more complex errors or persistent issues, it’s recommended to consult the tractor’s user manual or contact a qualified Kubota service technician for assistance.

Attempting to reset errors without proper knowledge or training may inadvertently cause further damage to the tractor or compromise its safety and performance.

How to Reset Errors on Kubota Tractor

When the Kubota tractor instrumental panel detects something wrong, the master system warning indicator (1) starts blinking and the error code indicating the location of the trouble. Showed in below is displayed on the LCD.

Mode “A” (Test Mode)

1. While holding down both DPF INHIBIT switch and parked regeneration switch, turn the key switch to “ON” or “START” position.
2. Mode selection display is indicated on the Kubota LCD.
3. Press the parked regeneration switch and the mode indicated on the LCD is changed.
4. If “A” is indicated on the LCD, press the parked regeneration switch for more than 2 seconds.
5. Kubota tractor test mode is selected.
6. If parked regeneration switch is pressed, the display item is changed.
7. Turn off the tractor key switch to finish test mode.

Mode “B” (Error Information Clear Mode)

1. While holding down both DPF INHIBT switch and the parked regeneration switch, turn key switch “ON” or “START” position.
2. Mode selection display is indicated on the Kubota dash LCD display.
3. Press the parked regeneration switch and the mode indication on the LCD is changed.
4. If “B” is indicated on the LCD, press the parked regeneration switch for more than 2 seconds.
5. Error information Clear mode is selected and the expression “PUSH” is displayed.
6. Press the parked regeneration switch for more than 2 seconds.
7. The expression “OFF” is displayed.
8. Turn off the tractor key switch.

Be sure to clear Kubota tractor error information by performing this procedure after servicing is finished.

What is a Kubota Tractor Regeneration Process?

Watch this helpful video about operation tips for when your tractor signals that the regeneration process is underway.

Kubota’s Automatic Regeneration System effectively eliminates accumulated soot within the DPF muffler, ensuring its cleanliness and enabling extended working hours.

As a safety measure, the automatic regeneration feature can be deactivated in fire-prone environments. Nevertheless, if the operator disables the regeneration process more than three times, the Kubota engine will activate auto-regen mode autonomously.

Most common Kubota Tractor Error Codes

These error codes can be caused by various issues, such as wiring problems, sensor failures, or ECU malfunctions. It is recommended to consult the tractor’s manual or contact a Kubota dealer for troubleshooting steps and possible solutions:

• E-20: Communication trouble – This error code is associated with a communication problem between the tractor’s electronic control unit (ECU) and other components. It may be caused by a broken electrical connector, a blown fuse, or a malfunctioning sensor.
• E-21: Range gear shift (Hi) switch trouble – This error code indicates a problem with the range gear shift (Hi) switch. It may be caused by a malfunctioning switch or a wiring issue.
• E-60: Proportional reducing valve failure – problem with the hydraulic system, specifically with the reducing valve, which controls the hydraulic pressure to the implement.
• E-94: Relay for engine-shut-off is in trouble – This error code indicates a problem with the relay for engine-shut-off. It may be caused by a faulty relay or a wiring issue.
• P-0087: Pressure limiter opening abnormality – This error code is associated with a problem with the pressure limiter. It may be caused by a faulty pressure limiter or a wiring issue.
• P-0088: High rail pressure abnormality – This error code is associated with a problem with the rail pressure. It may be caused by a faulty pressure sensor or a wiring issue.
• P-0088: High rail pressure abnormality – This error code is associated with a problem with the rail pressure. It may be caused by a faulty pressure sensor or a wiring issue.
• P-0563: Battery voltage abnormality (High) – Open circuit, short circuit or damage of harness. Failure of battery. Poor starting. Insufficient output. Deterioration of emission performance.
• P-0093: Fuel Leak (in High Pressured Fuel System) – Fuel leakage from high-pressure fuel system (when excessive fuel consumption is detected by calculating the difference in the rail pressure before and after fuel injection). Insufficient output. Deterioration of emission performance. * Engine stopped.

These Kubota DTC error codes cover a range of potential issues related to engine temperature, fuel system, and sensor malfunctions. Proper diagnosis and repair are essential to address these problems effectively.

Whate is Kubota SPN Error / FMI Error code?

Kubota SPN (Source Physical Number) and FMI (Fault Mode Identifier) error codes are used in the J1939 diagnostic protocol to identify specific faults in the tractor’s systems. These codes are part of the SAE J1939 diagnostic protocol used in modern vehicles and machinery to communicate faults and malfunctions.

• SPN (Suspect Parameter Number): This is a numeric value assigned to specific parameters or signals within the vehicle’s electronic systems. Each SPN corresponds to a particular aspect of the vehicle’s operation, such as engine speed, coolant temperature, or hydraulic pressure. When a fault or malfunction occurs, the SPN helps identify which parameter is affected.
• FMI (Failure Mode Identifier): This is a numeric value that provides additional information about the nature of the fault or malfunction associated with a particular SPN. The FMI describes the type of failure or the condition that triggered the diagnostic trouble code (DTC). It helps technicians understand whether the fault is intermittent, a short circuit, an open circuit, or another specific failure mode.

Together, SPN and FMI codes help technicians diagnose and troubleshoot issues with Kubota tractors and other equipment by providing specific information about the nature and location of faults within the vehicle’s electronic systems. These codes are typically accessed using diagnostic tools connected to the vehicle’s onboard diagnostic port.
