Start the engine and let it warm up.
When the coolant temperature is above 70 °C, the central unit orders the
stepper motor to perform 45 steps.
Select the menu from the “PARAMETERS” function. Check the number of “STEPS” defined
by the central unit for the start-up.
This setting varies according to the engine temperature. 20° C = ~ 80÷90 steps
Select the menu from the “ERRORS” function. Check the stepper motor for anomaly detected by the central
unit.
In order to check the stepper motor and its circuit, proceed as follows:
Connect the diagnostic multimeter.
Move the key switch to the “ON” position, the emergency stop to “RUN” and lift the side stand.
