If the CO value is lower than 0.7, close the bypass screw (20) of the relative cylinder by a 1/4 turn and wait 15 seconds before
taking the exhaust gas reading again.
If the CO value is correct, check the idle speed rpm: this should be between 1250±1350 rpm (1300±50 rpm); if the rom is not in
this specified range, repeat the adjustment procedure described in "Resetting the TPS".
If the adjustment does not produce a positive result, carry out the "Cylinder synchronisation" procedure described below to make
sure that the vacuum levels produced in the intake manifolds are balanced.
Cylinder synchronisation
Connect the Measurement Module cable (3) to the Measurement Module connector on the DDS (see paragraph "Description of
the Ducati Diagnostic System instrument").
Connect the vacuum/pressure pipes (6) to the connectors (A) and (C) of cable (3) and connect the fittings (7) to the pipes.
Switch on the DDS tester; see heading "Tester Power Supply".
Enter the "Measurement module" function. Press the "Cylinder synchronisation" icon.
The socket to which the Measurement Module cable (3) is to be connected is indicated on the screen with a capital letter: A, B
or C. Remove the screws (21) from the cylinder heads and install the fittings (7) in their place.
