Got a Harley? Keep it running well!
Harleys are fun to ride. But they sometimes show warning lights. Do you know what these lights mean? Let’s find out together! Checking your Harley’s codes can tell you if it needs help.
What Are Diagnostic Codes?
Codes are secret signals. Your bike’s computer uses them to talk to you. The computer checks everything. Everything must work right. If not, the codes will tell you so.
Steps to Check Your Harley’s Codes
- Find your bike’s menu screen. It’s where all information shows up.
- Turn the ignition to On. This is how you start checking codes.
- Also, turn the handlebar kill switch to On.
- Push the odometer reset button. Keep holding it down.
- Turn the ignition to Off then back to On.
- Watch the screen. It’s going to say “DIAG”.
- Release the reset button. You’re doing great so far!
Next, we’ll look at the types of codes.
Types Of Diagnostic Codes
There are current (C) codes and historic (H) codes. C means it’s happening now. H means it happened before. Knowing both is smart.
Finding the Codes Table
Here’s a table with common codes. You can find what each one means.
| Code | Type | Meaning |
|---|---|---|
| U1300 | C/H | Speed signal issue |
| P0107 | C/H | Air pressure low in engine |
| B1121 | H | Left turn signal problem |
