John Deere skid steers are known for their reliability, durability, and advanced onboard technology. However, even the most dependable machines occasionally display fault codes or diagnostic codes when something needs attention. Knowing how to reset John Deere skid steer fault codes and troubleshoot potential issues can save valuable time and keep your projects on schedule.

This updated guide explains how to identify, troubleshoot, and clear diagnostic codes on John Deere skid steers, including popular models like the 320D, 316 P-Tier, and other recent series. You’ll also learn when to seek professional service and how preventive maintenance can help reduce downtime.

What Are John Deere Diagnostic Codes?

John Deere diagnostic codes, sometimes called error codes or fault codes, are generated by your skid steer’s onboard computer when the system detects a problem. These codes help operators and technicians pinpoint the root cause quickly.

Common Signs You Have Active Fault Codes

• Warning lights or dashboard indicators.
• Error messages displayed on the monitor.
• Reduced machine performance or unexpected shutdowns.

Step-by-Step Guide to Clearing Codes on a John Deere Skid Steer

Follow these steps to identify, diagnose, and clear diagnostic codes on most modern John Deere skid steer models.

Step 1: Identify the Fault Code

1. Press MENU on the monitor and hold for 5 seconds until “CODES” appears.
2. Press SELECT to view both machine and engine diagnostic codes.
3. Record any displayed codes for reference.
4. Use your operator’s manual or an official code reference to understand each issue.

Step 2: Diagnose the Problem

1. Review the description associated with the fault code.
2. Inspect the relevant system or components. For example, a fuel-related code may require checking fuel filters, lines, or injectors.
3. Look for visible damage, loose wiring, or worn parts.

Step 3: Perform Basic Troubleshooting

Some issues can be resolved without advanced tools or professional service:

• Replace clogged filters.
• Tighten loose connectors.
• Clear debris from sensors or components.

Step 4: Reset the Fault Code

Once the underlying problem is addressed:

1. Press MENU for 5 seconds until “CODES” displays.
2. Press SELECT to enter diagnostic codes.
3. Scroll through until END appears.
4. Press SELECT again (“WAIT” will display).
5. Hold SELECT for 5 seconds to clear all stored codes.
6. If the fault code reappears, the issue may require deeper investigation or professional diagnostics and service.
