Riding Modes; The Battery Charging Circuit And Power Distribution - Ducati Diavel Workshop Manual

Introduction to the electrical system of the Diavel
- Self test accelerometer error / AccY offset error
- Run time accelerometer error
- Pin state accelerometer error
- Sensor power supply error
Warning
Faults relative to DTC are only detected if DTC is enabled. In the event of any wheel speed sensor faults or internal BBS
faults, DTC is disabled.

Riding Modes

The rider may select between four different riding modes (Sport, Touring, Urban and Enduro) from the dashboard and via
the "turn indicator reset" button (3). Each riding mode contains settings for the following:
- The DTC set-up (Sect. 6 - 7
- One of the three different maps of throttle opening (Sect. 6 - 9,
wire system)
The rider may modify the parameter settings of each riding mode or restore the default settings. The default settings are
summarised in the following table.

The battery charging circuit and power distribution

On the Diavel, the +15V (KEY ON power) voltage does not come from a conventional ignition key, but from PIN 30 of the
Hands Free relay. This relay is switched to closed state by the Hands Free unit when the latter enables power on for the
ignition and engine. The Hands Free relay receives +30V voltage (battery voltage), protected by a general 30A fuse.
The three phase alternator has three windings (l1, l2, l3), connected to one another in a "triangle" or "delta"
configuration. The electrical terminals R, S and T are connected to the voltage regulator.
The drawing illustrates the "triangle" or "delta" configuration connection of the three windings of the three phase
alternator.
The voltage regulator is constructed with specific electronic circuits (using MOSFET instead of SCR diodes) which limit
operating temperature and, as a result, improve reliability. The regulator can withstand a maximum current of 50A
(maximum current for the regulator used on SBK models is 35A) and has integrated waterproof electrical connections.
In the event of incorrect battery voltage (too low or too high), the message "Battery" is shown in the service display. The
DDS also indicates if an excessively low or high battery voltage is detected (Battery voltage diagnosis: High voltage, Low
voltage).
