Note
Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground.
Check integrity of electric circuit - short-circuit to ground = with the battery cables disconnected, using an ohmmeter, continuity is detected between the wire tested and ground.
Check integrity of electric circuit - open circuit = with the battery cables disconnected, using an ohmmeter, no continuity is detected between the two ends of the wire tested.
Low beam lights not working
Turn indicators not workingIndicator speed avg - average speed
This function shows the average speed of the motorcycle.

This function identifies any abnormal vehicle behaviours.
The dashboard activates any abnormal vehicle behaviours in real time (errors).
At key-on (at the end of the check) one or more "errors" are displayed in red
(only if they are active).
When an "error" is triggered, the indication (r ...
