Ducati Diavel Service Manual: Check the idle and the co amount with warm engine
- Start the engine;
- Switch on the dds and check that it does not signal any error (otherwise consult the relevant paragraph of this manual to reset the error and proceed with the idle check);
- Enter the "self diagnosis" menu by selecting the diavel model in the available vehicle version. Enter the "engine electronics" system and check the default parameters.
See list below:
- Rpm
- Engine temperature
- Air temperature
- Throttle valve aperture
- Map1 pressure sensor
- Map2 pressure sensor
- Wait for the engine temperature to exceed 80 C displayed on the dds, and then adjust only the by-pass screw of the vertical cylinder until the "map2 pressure sensor" parameter displayed on the dds is nearly -52kpa;
- Make sure that the system automatically keeps the idle between 1350 +- 100 rpm; in case the idle is too high check for no cuts in the pressure sensor wires, cracks or cuts in the intake manifolds, make sure that the latter are well fixed to the engine, and so on.
- Wait that the engine temperature exceeds 90C displayed on the dds; if the air temperature detected by the dds ranges between 19 C and 40 C the co in these engine temperature conditions must be within 0.4% And 2% on both cylinders; if this check is not successful try to replace the lambda sensor of the faulty cylinder and, in case the problem still occurs, inspect the faulty cylinder (clearance, strokes, valve sealing, etc.).
Warning
If the engine is shut off during the co level check, wait three minutes after starting for the after-starting enrichment phase to be finished and the lambda sensors to start operating.
Checking the idle speed
Check that the bike is provided with electronic control unit, oem intake and
exhaust systems, otherwise fit original
components.

Check the engine oil pressure
Note
The on-screen icons used during this procedure are explained in a table at
the end of this section.
To measure the pressure of the lubrication circuit, use the engine oil pressure

Key-on/key-off using the key on the hands free lock with the active key
Key-on can be performed by pressing the button (7) on the
hands free lock (1, fig. 77) And with the presence of the
active key (3, fig. 77).
Note
The active key (3, fig. 77) Has a range of approx. 1.5 M,
therefore it must be located within this range.
Key-off can be performed by pressing the ...
Checking and adjusting the valve clearances
Note
For clarity, the figures show the engine removed from the frame.
Move the piston of the cylinder being checked to tdc of the power stroke: in
this condition, all the valves are closed and
the timing shafts come in neutral position and, therefore, free to rotate; check
to the valve cl ...
Cylinder compression test
Note
The on-screen icons used during this procedure are explained in a table at
the end of this section.
Engine performance is directly correlated to the pressure that can be
measured in the combustion chambers of the two
cylinders. Pressure which is too high/low or an excessive difference be ...
