Ducati Diavel Service Manual: Operating principle

Introduction

The hands free system features two separate on/off buttons, either one of which may be used as preferred by the rider.

For practical reasons, we recommend using the button on the handlebar rather than the button located underneath the plastic shield covering the hands free system (in front of the tank).

In order to be able to turn the motorcycle on, the active key (which may be kept in the pocket, for instance) must be within 1.5 Metres from the antenna located inside the document compartment under the seat. In case the active key charge is low or ignition by means of the passive key it is necessary to start the bike while keeping the key against the antenna.

If the steering lock is locked and the key is recognised, pressing the on/off button automatically disengages the lock.

Pressing and holding one of the two on/off buttons causes the hands free system to send a radio signal to the key commanding it to "wake up" its internal electronic circuit. This function prevents the battery inside the key from draining when not in use, in other terms, when out of range or when the motorcycle is switched off. In these conditions, the internal circuit goes into a standby state. When the key receives the "wake up" signal, it activates its internal circuit and begins transmitting the unlock code to the hands free by radio. If the unlock code received by the hands free system is correct, engine start is enabled and the dashboard switches on.

The procedure for using the passive key (or for using the active key in transponder mode) is similar to the procedure with the active key. However, the passive key has no internal battery providing power for transmission, and the power necessary is received from the hands free system antenna instead. For this reason, the passive key must be aligned perfectly with and placed close to the antenna to ensure that it is powered and recognised. When the electronic circuit inside the key receives power from the antenna, it begins to transmit the unlock code to the hands free system. If the unlock code is correct, engine start in enabled and the dashboard switches on.

Two keys are provided with the motorcycle: one active key and one passive key. The active key has its own battery and communicates remotely with the hands free system, whereas the passive key, which is only used if the active key is not working, must be placed over the antenna (transponder mode - emergency start). The mechanical part of the key is used to open the saddle and fuel cap locks (if the vehicle is not equipped with electric locks). The two keys are shown below.

Warning

Never ride the vehicle with either of the keys (active or passive) inserted in the fuel cap or saddle lock as this may damage the mechanical part of the key or its internal electronic circuits.

Warning

Never leave the key on the vehicle when washing the vehicle itself as the key is not watertight and may be damaged.

How to turn the motorcycle on

In order to switch the dashboard on and start the engine, the active key must be within 1.5 Metres from the bike seat covering the receiver antenna.
