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.
Location of right hand fan connection.
Location of left hand fan connection.

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.

Refitting the steering head components
Important
The steering tube bearings (6) are identical but in no case may their
components be swapped around during reassembly.
Clean all contact surfaces and lubricate with the recommended grease.
To fit the external rings (c) of the bearings (6) to the steering tube, use the
tool with par ...
Low battery level
The activation of this (amber yellow) "warning" indicates
that the status of the battery vehicle is low.
It is activated when the battery voltage is . 11.0 Volt.
Note
In this case, ducati recommends charging the battery
as soon as possible with the specific device, as it is possibl ...
