These error codes can be retrieved from the machine’s display system or through a diagnostic tool. They serve as the first step in identifying problems that could lead to decreased performance, costly repairs, or machine downtime if left unaddressed.
Common Causes of Error Codes
Error codes can appear for a variety of reasons, including:
- Engine-related Issues: These could involve the fuel system, air filters, or exhaust emissions.
- Hydraulic Problems: A drop in pressure or a malfunction in the hydraulic pump could trigger an error.
- Electrical Failures: Problems with wiring, sensors, or battery voltage may also cause error codes.
- Sensor Failures: If a sensor becomes damaged or fails to relay accurate data, it could lead to an error code.
- Software Issues: Occasionally, a software glitch can trigger an error code, even if there is no mechanical problem.
Resetting error codes after the issue has been addressed serves several important functions:
- Clearing Faulty Messages: Sometimes, error codes may remain on the display even after the problem has been resolved. Resetting the codes ensures that the system is cleared of any false alarms.
- Preventing Misdiagnosis: If error codes are not cleared, it may be harder to identify new issues as the system continues to display old, irrelevant codes.
- Ensuring Proper Machine Operation: Some machines may not operate correctly with unresolved codes on the display. For example, certain functions may be locked out or the machine may be forced into “limp mode” to protect the engine or hydraulics from damage.

Step 2: Access the Diagnostic System
To reset the error codes, you need to access the diagnostic system on the excavator. This is usually done via the monitor display on the machine’s dashboard.
- Navigate to the Diagnostics Menu: From the main menu, find the diagnostics section on the screen. This is where the error codes are displayed. Depending on the machine’s configuration, you may see a specific icon for diagnostics or a dedicated option for error codes.
- View the Stored Error Codes: In the diagnostics section, you should be able to access a list of all the error codes that the machine has recorded. These codes will typically appear as a series of numbers or alphanumeric characters.
Before resetting the error codes, it’s important to understand what each code represents. John Deere provides a detailed error code manual for their equipment, which can help you interpret the meaning of each code. Common codes on the 290G LC may include engine malfunctions, hydraulic system issues, or sensor errors.
- Error Code Example:
- SPN 1234 FMI 9: This code might indicate a sensor issue related to the engine speed.
- SPN 5678 FMI 4: Could refer to a hydraulic pressure issue or a low oil level.
- SPN 1234 FMI 9: This code might indicate a sensor issue related to the engine speed.
Step 4: Reset the Error Codes
Once the issue has been addressed, you can proceed with resetting the error codes. There are two common methods for resetting these codes:
- Method 1: Manual Reset
- In the diagnostics menu, look for an option labeled “Reset Codes” or “Clear Faults.”
- Select the reset option, and the machine will clear all stored error codes.
- Confirm that the codes have been cleared by checking the diagnostics screen again. If the screen shows no active fault codes, the reset was successful.
- In the diagnostics menu, look for an option labeled “Reset Codes” or “Clear Faults.”
- Method 2: Disconnecting the Battery
- If the error codes persist after a manual reset, another method is to disconnect the excavator’s battery for about 15-30 minutes.
- Reconnect the battery and power on the machine. This should reset the system and clear the stored error codes.
- Verify that the codes are no longer showing on the display.
- If the error codes persist after a manual reset, another method is to disconnect the excavator’s battery for about 15-30 minutes.
After clearing the codes, it’s important to test the machine by operating it through various functions. This ensures that everything is working as expected and no new error codes appear. If new codes appear, this might indicate that the issue persists, or another underlying problem needs attention.
