Fault codes
Dds: horn diagnosis -> short circuit to ground (s.C. Gnd).
Dashboard: the error "claxon" (horn) is shown on the service display. The eobd warning light activates.
Wiring diagram

Note
Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground.
Check integrity of electric circuit - short-circuit to ground = with the battery cables disconnected, using an ohmmeter, continuity is detected between the wire tested and ground.
Check integrity of electric circuit - open circuit = with the battery cables disconnected, using an ohmmeter, no continuity is detected between the two ends of the wire tested.
Low beam lights not working
Turn indicators not workingFuel system circuit
The fuel system circuit consists of:
An electric pump, driven by the injection relay, which is in turn
controlled by the ecu (engine control unit)
A fuel filter
A pressure regulator
Two injectors (one per cylinder, located downstream of throttle valve)
The plastic mounting shown in t ...
Bleeding of the abs hydraulic system
If some "sponginess" is detected on the brake control, due to air bubbles in
the system, bleed the system, as indicated in
sect. 4 - 3, Changing the brake fluid.
Before bleeding a brake pump, move back the calliper pistons, as indicated in
(sect. 4 - 3, Changing the brake fluid) to Drain in ...

idle rpm.
To access the function it is necessary to view the ""setting" menu", using
buttons (1) "s" or (2) "t" select the "rpm"
function and press the reset button (3) to confirm.
