Steps to Clear Codes on Harley Davidson
Clearing codes on a Harley Davidson involves accessing diagnostic mode, reading and interpreting the codes, and erasing the error codes. Here’s a detailed guide to each step.
Accessing the Diagnostic Mode
First, access the diagnostic mode by turning off the bike’s ignition. Hold the trip button on the instrument panel, then turn the ignition back on without starting the engine. Release the trip button when the diagnostic menu appears. This menu allows access to the stored error codes for further inspection.
Reading and Interpreting Codes
Navigate the diagnostic menu using the trip button to scroll through the various modules. Each module displays specific codes related to potential issues, such as “P” for powertrain, “B” for body, “C” for chassis, and “U” for network communication. Write down these codes, then refer to the Service Manual for accurate interpretations. Understanding the meanings aids in identifying the motorcycle’s issues.
Erasing the Error Codes
Once interpreted, you can erase the error codes by re-entering the diagnostic mode. Use the trip button to navigate back to the code you wish to clear. Hold the trip button until “CLEAR” appears on the display, then release. Confirm the code’s erasure and exit the diagnostic mode by turning the ignition off. Removing these codes won’t fix underlying issues, so ensure to address them accordingly for optimal performance.
Common Issues and Troubleshooting Tips
Harley Davidson riders encounter various error codes that can signal maintenance needs. Understanding these codes aids in quick troubleshooting, helping to prolong the bike’s performance.
Frequent Error Codes and Their Meaning
- P0107 (MAP Sensor Circuit Low): Indicates a problem with the manifold absolute pressure sensor circuit, often leading to poor engine performance.
- U1255 (Missing Message at Speedometer): Points to communication failure between the engine control module and speedometer, affecting data display.
- P0131 (Front O2 Sensor Low Voltage): Suggests an issue with the oxygen sensor, typically resulting in inefficient fuel combustion.
- B1121 (Left Turn Output Fault): Refers to a malfunction in the left turn signal, needing inspection of the bulb connections.
- Regular Maintenance Checks: Conduct routine inspections and service appointments every 5,000 miles to catch potential issues early.
- Use Quality Fuel: Ensure the use of high-octane gasoline recommended by Harley Davidson to maintain engine health.
- Update Software: Keep the bike’s software current to benefit from the latest features and diagnostic improvements.
- Inspect Electrical Connections: Periodically check wiring and connectors for wear or looseness to avoid electrical faults.
Maintaining a consistent maintenance routine and addressing error codes promptly enhance both the longevity of the motorcycle and the rider’s experience.
