Introduction
The radiator fans are powered via a specific relay, which is enabled by the engine control unit.
Component assembling position
A injection relay; b etv relay (throttle valve actuator motor), c radiator fan relay, d engine control unit.

In the event of fault
In the event of a radiator fan relay fault, the radiator fans themselves do not work. The relay is not commanded by the ecu.
Fault codes generated and possible correlated faults fault codes generated by the engine control unit and displayed by the dds (fan relay diagnosis):
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.
The dashboard service display shows the error "fan relay" and the eobd warning light activates.
Possible correlated faults: coolant reaches boiling point but radiator fans not working. Check:
The radiator fan relay may be actuated from the dds to check radiator fan function.
The fans are normally activated at 103 and switched off at 101C.
If none of the aforementioned tests identify the problem and the radiator fan relay is in proper working order, replace the engine control unit.
Component replacement methods
No special measures are necessary in order to replace the radiator fan relay.
Recovery procedure in the event of electric steering lock fault
If any fault occurs during activation of the electric steering lock: for
example, if the pin jams, if the handlebar is moved
while the pin is deployed or if there is excessive strain on the electric pin
actuator motor, the electric steering lock is
automatically disengaged and the hands free s ...
Description of the clutch assembly
The clutch is disengaged by a drive unit consisting of a thrust piston (c)
accommodated inside a small cap mounted to
the generator cover. This piston (c) pushes a pushrod (b), which runs through
gearbox primary shaft and operates the Pressure plate (4)
located on top of the clutch plate pack ...
Changing bulbs
Changing the headlight bulbs
Before replacing a burnt out light bulb, ensure that the replacement bulb has
the same voltage and power rating as
specified for the lighting device in question (sect. 3 - 1.1, Lights/instrument
panel).
Warning
The halogen light bulbs in the headlight become hot ...
