1) Place the scooter on its main stand.
2) Turn the ignition switch ON. The CELP (Check Engine Lamp) will light for two seconds then turn off to show the lamp is working. If the ECU detects any faults then the lamp will stay lit.
3) Start the engine and let it idle. If the CELP does not light or blink, the system has no memory of problem data. If the CELP lights or blinks, stop the engine and read the failure codes by performing the following:
3a) Turn ignition switch to OFF and hold the throttle fully open.
3b) Turn ignition switch to ON. The CELP comes on for 2 seconds, then turns off.
3c) Close the throttle fully when the CELP comes on again.
3d) When the CELP begins to blink, it is showing the failure codes.
The number of blinks are from 1 to 24, excluding numbers 20 and 23.
3e) When more than one failure occurs, the CELP shows the blinks in the order of lowest number to highest number.
All the failure codes will be blinked repeatedly until cleared from memory.

If you're in the San Francisco Bay Area, let me know. You can drop by and use my Diagnostic Tool to troubleshoot it. It gives more comprehensive data than just the blink codes.
