Bobcat Engine Error Codes are diagnostic codes generated by the onboard electronic control unit (ECU) of Bobcat machines, such as mini excavators, compact track & skid steer loaders, telehandlers, wheel loaders, and other construction equipment. These codes serve as a communication system between the machine and the operator, indicating specific issues or potential problems with the engine or its associated systems.
Each error code corresponds to a specific problem, such as fuel system malfunctions, engine overheating, sensor failures, or electrical faults. Bobcat engine codes pinpoint the exact component or system requiring attention, reducing the time spent diagnosing issues. Some codes may indicate minor issues (warnings), while others signal critical problems that may require immediate action. Codes are typically displayed on the machine’s control panel or digital screen, often accompanied by warning lights or audible alarms.
Bobcat Engine Error Codes
General engine issues codes indicate problems such as low oil pressure, high coolant temperature, or emissions system faults. Electrical system errors include battery issues, alternator malfunctions, or sensor communication errors. Enhanced Efficiency: Accurate diagnostics reduce machine downtime and improve overall productivity. By decoding these error messages, operators and technicians can maintain Bobcat equipment in peak operating condition, ensuring both performance and longevity.

How To Clear Bobcat Engine Error Codes
Clearing Bobcat engine error codes typically involves diagnosing and resolving the issue that triggered the code, followed by resetting the machine’s onboard computer. Here’s a step-by-step guide to clearing error codes on Bobcat equipment:
Identify and Address the Cause
- Consult the Operator’s Manual: Look up the error code in the manual to understand its meaning and possible causes.
- Inspect the Machine: Check the relevant system or component (e.g., sensors, wiring, fuel lines) for faults or damage.
- Perform Necessary Repairs: Fix or replace faulty parts, refill fluids, or recalibrate as needed to resolve the issue.
Reset the Error Code
- Turn Off the Machine: Shut down the engine and turn off the ignition. Wait a few minutes to ensure the ECU powers down completely.
- Restart the Machine: Turn the ignition back on without starting the engine. Wait for the diagnostic system to complete its self-check.
- Check the Control Panel: If the issue is resolved, the error code may clear automatically. If the code persists, proceed to the manual reset or ECU tools.
Perform a Manual Reset (if needed)
For some models, the following steps may help reset the code:
- Access Service Mode: Press and hold specific buttons on the control panel (consult your operator’s manual for exact instructions).
- Navigate to Error Code Settings: Use the control interface to locate the error code list.
- Clear the Code: Follow the prompts to clear the displayed codes.
Use Diagnostic Tools
- Bobcat Diagnostic Software or Scanner: Connect a diagnostic tool compatible with Bobcat’s system. Access the ECU and use the software to erase error codes after resolving the underlying issue.
- Dealership Assistance: For persistent codes, visit a Bobcat dealership or authorized service center for professional diagnostics and resetting.
Confirm the Reset
- Run the Machine: Operate the equipment to ensure the error does not reappear.
- Monitor Performance: Check for smooth operation and verify that no new codes are triggered.
If the error code returns immediately after resetting, the issue has not been fully resolved. Double-check diagnostics and repairs. Disconnect the machine’s battery for 10–15 minutes, then reconnect it. This may reset the ECU and clear codes. Use caution, as this method might erase other settings. Always follow safety procedures when working on heavy equipment.
By following these steps, you can effectively clear error codes and maintain optimal performance of your Bobcat equipment.
Understanding engine error codes is vital for maintaining the performance and reliability of Bobcat mini excavators and skid steer loaders. These codes are part of the advanced diagnostic system designed to alert operators to potential issues within the machine’s engine or related systems. From minor maintenance needs to critical malfunctions, error codes play a crucial role in identifying problems early, minimizing downtime, and reducing repair costs.
