Ducati Diavel Service Manual: Communication antenna

Introduction

The communication antenna enables the hands free system to detect and communicate with the active or passive key.

The active key is detectable within a range of 1.5 Metres, whereas the passive key (or active key with flat battery) can only be detected if placed in contact with the lower part of the clear plexiglas windscreen covering the antenna.

An antenna fault will compromise correct key detection.

Wiring diagram

Communication antenna


The communication antenna is connected to the hands free system by two cables and a dedicated connection.

  1. Blue/black (b/bk)
  2. Red/yellow (r/y)

Error codes

"Hands free diagnosis" error: "antenna": antenna not detected (open circuit) or antenna short circuited. The following icon appears on the tank dashboard:


Note

Checking the integrity of the electrical circuit entails the following actions:

Short circuit to vdc: with the dashboard on, use a voltmeter to measure the voltage between the wire being tested and ground.

Short circuit to ground: with the battery cables disconnected, use an ohmmeter to check for continuity between the wire being tested and ground.

Open circuit: with the battery cables disconnected, use an ohmmeter to check that there is no continuity between the two ends of the wire being tested.

Electrical characteristics and checking component

The resistance between the two terminals of the component side connection must be approximately 2 ohm.

In the event of fault

In the event of a component fault, the hands free system can no longer detect and recognise the keys. The pin code procedure must be used to start the motorcycle.

Component replacement methods

No special measures are necessary in order to replace the hands free system communication antenna.

The hands free module
Introduction The hands free module incorporates the control unit communicating with the other nodes on the motorcycle, the on/off button, the microswitches detecting full lock steering angle (for ...

On/off switch on handlebar
Introduction The on/off switch on the handlebar is used to switch the dashboard on and off, if a key has been detected, and start the engine. With the switch turned to "run off" (centre positio ...

Checking and adjusting the valve clearances
Note For clarity, the figures show the engine removed from the frame. Move the piston of the cylinder being checked to tdc of the power stroke: in this condition, all the valves are closed and the timing shafts come in neutral position and, therefore, free to rotate; check to the valve cl ...

Beam setting
When checking beam setting, put the motorcycle upright. Tyres should be inflated at the correct pressure and one person should be sitting astride the motorcycle, keeping it at right angles to its longitudinal axis. Place the motorcycle opposite a wall or a screen, 10 meters apart from it, draw ...
