Horn Button; Turn Indicator Switch (Turn); Control Switch (Set Up) (Set Down); Low Beam And High Beam (Hi Beam) - Ducati MONSTER 821 Workshop Manual

CONTROLS ON LEFT-HAND SWITCH

HORN button (2)

Connect the terminals of a multimeter to the Red/Blue and White/Blue cables to check for electric
continuity, which must be available when HORN is pressed.
- When the HORN button is pressed, the resistance value read by the multimeter should be close to zero
and, if available, a continuity beep should be heard.
- When the HORN button is not pressed, the resistance value should be infinity (there is no continuity as
the electrical contacts inside the push-button are open) and no continuity beep should be heard, if provided.
If these conditions are not met, the device must be replaced.

Turn indicator switch (TURN) (3)

The turn indicators cancel button may also be used in the instrument panel for the CONFIRM MENU
function, for selecting the riding mode.
Push this button for 3 seconds to the left side to activate the "Hazard" function (all 4 turn indicators).
Connect the multimeter to the Red/Blue and Grey wires arriving from the turn indicator switch and check
for electrical continuity when operating the right turn signal.
Repeat the above procedure for the left turn indicator, but connect the multimeter to the Black and Grey
wires.

Control switch (SET UP) (SET DOWN) (4) (5)

Buttons used to display and set instrument panel parameters.
Connect the multimeter to the Red and Black wires arriving from the instrument panel function selector
switch and check for electrical continuity when pressing button (4).
Repeat the same procedure, press button (5) and connect the multimeter to the Red/Blue and Blue/Yellow
wires.

Low beam and high beam (Hi Beam) (6)

Test using the same procedure, applying the probes of the meter to the Red/Blue and Blue wires and
moving switch down.
Flash switch (PASSING) (6)
The high-beam flash button may also be used for LAP functions.
Check for continuity between the Red/Blue and Orange wires.
Unlike the Hi Beam, switch (6) should be pressed.
