How to Clear Codes on a Harley Davidson


If you own a Harley Davidson motorcycle, you may occasionally see a check engine light. The light can be a sign of a variety of problems, but it is frustrating nonetheless. To make things easier, you should learn how to clear codes on a Harley Davidson motorcycle. It is also helpful to know the codes retrieved from the light. You should be able to perform this process yourself in the event that the light reappears.

Diagnostic trouble codes

If your bike is acting up, you may want to clear the diagnostic trouble codes to find out what the problem is. To do this, you will need to turn off the ignition, hold down the reset button, and then push it again. The next step will be to run the bike and see if any other codes are stored. Occasionally, your bike may be displaying warnings about something that’s not a major problem.

Before you can clear the diagnostic trouble codes, you must have some knowledge of motorcycles. Basically, Harley-Davidson trouble codes are a series of letters and numbers. When the codes are triggered, your motorcycle may need to be taken to a shop. The motorcycle will need to be run through several cycles to clear the trouble codes. Eventually, a technician will need to check the motorcycle’s computer for the cause of the trouble.

Check engine light

A Harley Davidson check engine light may illuminate, indicating the need to have your bike checked out. This light may contain a number of trouble codes. You can attempt to clear the trouble codes yourself, but remember that clearing these codes does not fix the problem. Once you have the code, you can visit a Harley-Davidson service center or dealership for professional diagnosis. But before you try to clear the trouble codes yourself, read this article to learn how to clear check engine light codes on Harley Davidson.

If the motorcycle’s check engine light does not go away after several attempts, you might need to have your vehicle checked out by a mechanic. In such cases, you can use a free application designed for Harley owners. The Harley DTC application looks up diagnostic trouble codes and displays them for you. Each code is explained in detail, including its definition. Moreover, it also comes with documentation. This tool can be extremely useful for anyone who owns a Harley Davidson.

Identifying faults

Identifying faults on Harley Davidson begins with the diagnostic check. Performing this diagnostic check is an organized approach to locating the fault that’s causing the misfire in the electronic control system. The key to identifying the problem lies in comparing the running parameters to those that are in-spec. An engine not running may indicate a mechanical failure in a number of areas, including compression, cam timing, and fuel system. In addition, a test lamp in place of the ignition coil can set the DTCs (Dig-Technical Control Unit) on the engine. Clearing these DTCs is not a difficult process, either.

Diagnostic trouble codes (DTCs) are stored in the vehicle’s memory. DTCs are either current or historic, and can be accessed with a digital technician or speedometer self-diagnostics. The DTCs reside in the ICM and TSM, and the DTC is stored in the memory. When a Harley Davidson experiences an electrical fault, the DTC may not be fully diagnosed until the engine starts, so it will give an incorrect indication of the fault.

Repairing faults

There are a few simple steps that you can take in order to diagnose your motorcycle’s faults. One common fault is the gas cap. The gas cap rattles despite two attempts to install channel locks. This problem was an oversight on the part of Harley’s development and engineering teams. It is possible to resolve this problem with a few dollars of spare parts, and it will pay to be able to identify the problem in the first place.

To repair your Harley Davidson, you must first diagnose the issue. First, look for a code. If the error code is ‘0’, this means the problem is with the brakes. Generally, brakes need to be replaced. If the brakes are too soft, they could lead to a crash. Brake components such as calipers are prone to wear out after a few years of use, so you should have them replaced before riding the bike.
