Ducati Diavel Service Manual: Throttle valve actuator motor relay

Introduction

The throttle valve actuator motor is powered by the engine control unit. The engine control unit receives the necessary power from a specific relay.

Component assembling position

Throttle valve actuator motor relay


A injection relay; b etv relay (throttle valve actuator motor), c radiator fan relay, d engine control unit.

Connection wiring diagram

Connection wiring diagram


Ccm engine control connection, t throttle valve actuator motor relay. 85 Throttle valve actuator motor relay activation, light blue/green - lb/g, 87 ecu power input for throttle valve actuator motor, red/brown r/bn, 30 and 86 red/purple - r/v, r battery positive (+30).

In the event of fault

In the event of a throttle valve actuator relay fault, the ecu cuts motor power and the throttle valves close (see chapter operating principle and characteristics of the ride-by-wire system in this section).

Fault codes generated and possible correlated faults

Fault codes generated by the engine control unit and displayed by the dds (etv 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 "etv relay" (throttle valve actuator motor relay) 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 one of the three preset positions (0%, 50%, 100%) using the dds. During motor actuation, the throttle valve actuator motor relay is driven.

If none of the tests described above identify the problem and the throttle valve actuator relay is in proper working order, contact ducati.

Component replacement methods

No special measures are necessary in order to replace the throttle valve actuator motor relay.

Injection relay
Introduction The fuel pump, injectors and ignition coils are all powered via the injection relay. The relay also sends voltage to the engine control unit, which enables activation of the relay its ...

Starter motor relay
Introduction When the rider presses the start button, with all the safety conditions required to enable engine start met, the engine control unit enables the relay that activates the starter motor ...

How to switch the dashboard on
The dashboard may switched on either from the on/off switch on the handlebar or from the button on the hands free system. With the engine off, the on/off switch is turned to "run off". With the motorcycle and dashboard off, the on/off switch is turned to "run off". To switch the dash ...

Entering pin code function for vehicle release
This function turns on the motorcycle "temporarily" in the case of hf (hands free) system "malfunctions". To activate the function, press the "emergency" hands free button (7, fig. 87) If the motorcycle cannot be turned on using the normal starter button. After ...

First warning - oil service 1000 km
The first warning is activated at 1000 km (600 miles) of odometer reading. The (red) warning is activated as a large icon for 10 seconds upon every key-on (1) then as a small warning that remains displayed (2) until it is reset. ...
