Display Error Codes: L300 and L04NH
Confirm your display model before using a code table. The same number can mean different things on different displays or firmware. Identify your bike and display first.
New Defiant ST: this model does not use the L300. Do not use the L300 table for it. Its exact display model is not confirmed here, and the L04NH table must not be assumed to apply. Send support a display photo and the exact code for the correct reference.

The supplied translation is unclear for codes 2 and 5. Send support a display photo for confirmation rather than using another display's definitions.
What to do with an error
Stop riding and photograph the full screen and exact code. Turn the bike off before inspecting visible cables. Do not open the controller, bypass sensors, or change factory parameters to clear the error. For low-voltage indications, follow the charging guide only if the battery and charger are undamaged. If the code persists or is not listed, contact support with your model and display photos.
