Introduction
The electric motor actuating the throttle valve for the vertical cylinder is mounted on the throttle body of the diavel, while a link rod connects the vertical cylinder throttle valve to the horizontal cylinder throttle valve. In the electric motor, the throttle valve position sensor (tps) is integrated.
The electric motor, which also incorporates the throttle valve position sensor (tps), is visible on the right, on the throttle body. The accelerator position sensor (aps) is visible on the left.

Component assembling position
The image shows the throttle valve actuator motor. Inside of it, it is also placed the throttle valve position sensor (tps).

In the event of fault
In the event of a throttle valve actuator fault, motor power is cut off and the throttle valves close (see chapter relative to ride-by-wire system).
Fault codes generated and possible correlated faults fault codes generated by the engine control unit and displayed by the dds (etv motor 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 "etv motor" (throttle valve actuator motor) and the eobd warning light activates.
Possible correlated faults: the engine does not start, cuts out or remains running at idle speed and will not accelerate.
Check:
The throttle valve actuator motor may be actuated into three preset positions (0%, 50%, 100%) using the dds.
If none of the tests described above identify the problem and the throttle valve actuator is in proper working order, contact ducati.
Component replacement methods
The throttle valve actuator motor incorporates the throttle valve position sensor (tps) and cannot be replaced as an individual component. In case it brakes down it will be necessary to fit a new throttle body (refer to sect. 6 - 8, Operating principle and characteristics of the ride-by-wire system). After replacement of the throttle body, reset the self-adaptive parameters relative to carburation with the dds. Adjust the cables connecting the throttle grip to the throttle grip position sensor.
Refitting the clutch master cylinder assembly
Insert the clutch master cylinder assembly (3) and the clamp (6) on the left
handlebar, so that the top mating faces
match the mark (z) on the handlebar as shown.
Couple terminal (6) to the clutch master cylinder control and fix them with
the screws (v).
Tighten the retaining screws ...
Immobilizer override procedure
This procedure makes it possible to "temporarily" turn on
the motorcycle if the hf (hands free) system is not working.
Note
The pin code function must be activated by entering
your 4 digit pin in the instrument panel, otherwise the
vehicle cannot be turned on temporarily in the case ...
