Overview of Harley Davidson Codes
If you've ever wondered what those mysterious check engine light codes on your Harley-Davidson mean, you're in the right place. Harley-Davidson trouble codes are used to diagnose issues indicated by the check engine light.
These codes are categorized into different modules such as the Engine Control Module (ECM), Body Control Module (BCM), Speedometer (SPDO), Radio (RAD), ABS, and TSSM.
Diagnostic Trouble Codes (DTC) provide directional information for diagnostic work and are essential for troubleshooting. However, understanding and interpreting the codes requires experience and practice. Technicians with diagnostic skills are in high demand in the motorcycle industry.
Different codes may apply based on the motorcycle's model year and options, and they help identify the root cause of the issue. When dealing with Harley-Davidson codes, it's important to note that each code is associated with a specific part number, which can aid in locating the necessary replacement part.
Common Harley Davidson Trouble Codes
Common Harley Davidson trouble codes are essential for diagnosing and addressing issues within your motorcycle's system. These diagnostic codes categorize faults into different areas, such as the Engine Control Module (ECM), Body Control Module (BCM), Speedometer (SPDO), Radio (RAD), ABS, and TSSM. Understanding and interpreting these codes can help you identify the root cause of the problem and troubleshoot it effectively.
Here are some common Harley Davidson trouble codes and their meanings:
| Trouble Code | Description |
|---|---|
| P0374 | Ignition Switch Fault |
| B1004 | Ignition Control Module Internal Fault |
| B1153 | Side Stand Switch Fault |
| U0141 | Lost Communication with Body Control Module |
These codes are just a few examples, and there are many more specific to different models and years of Harley Davidson motorcycles. When you encounter a trouble code, it is important to refer to the appropriate service manual or consult with a professional technician to understand the exact cause of the issue.
Understanding Harley Davidson Diagnostic Codes
To gain a comprehensive understanding of your Harley Davidson motorcycle's issues, it's important to familiarize yourself with the diagnostic codes used to identify and troubleshoot problems within the electronic control module (ECM) and various other systems. These diagnostic codes provide valuable information about the faults detected in your motorcycle. The codes are categorized into different systems such as ECM, BCM, SPDO, RAD, ABS, and TSSM, allowing you to pinpoint the specific area of concern.
When it comes to diagnostic codes, there are three types: current codes, historic codes, and pending codes. Current codes indicate an active fault that requires immediate attention. Historic codes remain saved until cleared and can provide insight into past issues. Pending codes record faults that haven't occurred enough times to set as current.
Fortunately, you don't need an external tool to access and understand these codes. Harley Davidson motorcycles have an onboard diagnostic feature that allows you to display the codes directly on the bike's instrument cluster. Simply turn on the ignition, press and hold the reset button, and then turn on the ignition again. The diagnostic codes will appear on the display, guiding you towards the root cause of the problem.
It is important to note that interpreting and understanding these codes may require some experience and practice. Clearing a code should also be done by a qualified technician to ensure proper diagnosis and resolution of the issue. So, take the time to familiarize yourself with these diagnostic codes, and you'll be better equipped to address any problems that may arise with your Harley Davidson motorcycle.
How to Interpret Harley Davidson Codes
To interpret Harley Davidson codes, start by turning off the ignition switch and setting the Run/Stop switch to Run. Then, push and hold the odometer reset button while turning the ignition switch to Ignition. Release the button and the diagnostics module selection menu will appear as 'PSSPt' with the first 'P' flashing. Each letter represents an area of the diagnostics module, and the flashing module is the one to check.
To view diagnostic trouble codes (DTCs), push and hold the odometer reset button for 5 seconds and release. If there are any DTCs, the code will be displayed. To determine the status of a code, clear the displayed code, turn off the ignition switch, run the bike, shut it down, and recheck the DTCs. If the code is current, it will reappear.
To continue and finalize the process, press and release the odometer reset button to move to the next module. Turn off the ignition switch and complete the troubleshooting process.
Here is a table that summarizes the steps to interpret Harley Davidson codes:
| Steps to Interpret Codes |
|---|
| 1. Turn off ignition switch |
| 2. Set Run/Stop switch to Run |
| 3. Push and hold odometer reset button while turning ignition switch to Ignition |
| 4. Release the button |
| 5. Check the flashing module in the diagnostics module selection menu |
| 6. Push and hold odometer reset button for 5 seconds and release to view DTCs |
| 7. Clear and recheck DTCs to determine code status |
| 8. Press and release odometer reset button to move to the next module |
| 9. Turn off ignition switch to finalize the process |
