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.

Reassembly of the crankcase halves
If removed, apply threadlocker on the screw (36), insert it with the washer
(37) on the crankcase half and tighten it to The torque of 8 nm
(min. 7 Nm - max. 9 Nm) (sect. 3 - 3, Engine torque settings).
If removed, apply threadlocker on the dowel thread (35), tighten it to a
torque of 20 ...
Fuel 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 ...
Injection relay
Introduction
The fuel pump, injectors and ignition coils are all powered via the injection
relay. The relay also sends voltage to the
engine control unit, which enables activation of the relay itself.
