These abbreviations, and the accompanying list of trouble codes, can be a great start when your KTM check engine light comes on. As mentioned above, if you are not comfortable with electrical diagnostic work, a dealership or qualified technician can offer assistance. Please keep in mind that even though you have the ability to clear a DTC using the onboard diagnostic feature, you shouldn't clear the code prior to your service appointment. Let the technician view and clear the codes as they troubleshoot the issue.
