Understanding the Harley’s Check Engine Light

The Harley’s check engine light is part of its onboard diagnostic system. This system monitors your motorcycle’s performance and alerts you to potential issues. When the light comes on, it’s signaling that the bike’s computer has detected an abnormality, which could be anything from a minor glitch to a significant mechanical problem.

Even though the check engine light is a warning signal, it doesn’t necessarily mean there is an immediate danger. It’s more of a notification that something needs your attention. It could be a simple issue that you can address yourself, or it could be a sign that your Harley needs professional attention.
