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 brake and clutch fluid level
The levels should not fall below the min marks on the respective reservoirs. If the level is too low, air can get into the circuit, thus impairing the efficiency of the system. Brake and clutch fluid must be topped up and changed at the intervals specified in the scheduled maintenance table ...

Programming/reprogramming keys
The dds diagnosis instrument is required in order to programme/reprogramme the keys. The key programming procedure is launched from this instrument. To start the key programming/reprogramming procedure it is necessary to have at least one of the keys that start the vehicle available (i.E. I ...

Recharging the battery
Examine the label on the battery showing the check intervals in order to determine when to test the voltage. Charge the battery if the open circuit voltage is lower than 12.8 V. Leaving the battery discharged for more than one month could damage it. Check the battery charge with a voltmete ...
