-To enter the diagnostic mode: +
-Before turning on the key, press and hold the trip button for the odometer (on the left handlebar). While pressing the button, turn on the key switch. When the odometer shows '​diag',​ release the button. +
- +
-There are multiple sections to the diagnostic mode that will display in sequence:​\\ +
- +
-^ Code Section | Related To: | +
-|  ECM         | Electronic Control Module | +
-|  BCM         | Body Control Module | +
-|  SPDO        | Speedometer | +
-|  ABS         | AntiLock Braking System (if present) | +
- +
-Press the trip button briefly in order to scroll through the various sections. +
- +
-If a section has a display of '​Y'​ next to its name (such as ‘ECM Y’) that section has a diagnostic code present. To display the diagnostic code(s) in that section, press and hold the trip button for 5 seconds. The first diagnostic code will be displayed. If there are no codes in that section (no Y next to the section name), you will see a display of ‘none’. +
- +
-Repeatedly press the trip button (briefly) to scroll through multiple error codes until you reach the display of ‘END’. After the ‘END’ display in each particular section, the next press of the trip button will display the part number of the module reporting for that section, such as the part number for the ECM / BCM / Speedo / ABS control module. +
- +
-Be sure to record all diagnostic error code(s) for later reference. +
- +
-In order to delete an error code, press the trip button while the diagnostic code is showing and hold it for 5 seconds - THIS WILL DELETE THE CODE and display ‘CLEAR’ (be sure to have recorded the code beforehand). +
- +
-Simply press the trip button repeatedly to scroll through any additional codes, to return to the section list or to scroll thru additional sections. +
- +
-When finished, turn the ignition switch to off to terminate the diagnostic mode. +
- +
-**Historic Diagnostic Codes** +
- +
-Each DTC that occurs is tracked historically. After the DTC has been resolved, or if a particular problem happens to resolve itself, the status of the DTC is dropped from being current and it becomes a historic DTC. Historic DTCs are stored for 50 ignition cycles after any DTC was last set as current. This may assist in the diagnosis of intermittent faults. On the 50th cycle, the DTC will clear itself. +
- +
-The check engine lamp will not indicate the existence of only historic DTCs. It is important to note that historic DTCs will exist whenever the system indicates the existence of a current fault. +
- +
-NOTE: To determine if a code was stored historically or is a current error will require you to reset the error and check again - Clear the displayed code by pressing and holding the odometer reset button ( longer than 5 seconds) until '​Clear'​ comes up. Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it down then recheck the DTC’s again as described above. If the code is current it will reappear. Historic codes can still be retrieved with computer-based diagnostic tools. +
