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 between the two cylinders will cause a drop in engine performance and can cause engine breakdowns.
To reach the vertical head spark plug lift the tank up as specified under the section 8 - 2 "removal of the fuel tank" and fit a drift under it.
Run the engine so that it warms up to the point that the fan is tripped at least once.
Open the throttles completely.
Remove the ht leads (1), unscrewing the nuts (2) of both spark plugs.
Remove the spark plug from the cylinder to be tested.
Connect the ht lead to earth to prevent sparking.
Screw the cylinder compression cable part no.552.1.038.1A into the spark plug compartment.
Connect the pressure sensor part no. 552.1.039.1A to the cable with part no. 552.1.038.1A..
Turn on the dds diagnosis instrument (3) referring to the paragraph "connection to the motorcycle".
Connect the power and diagnosis cable (measurement module) (4) part no. 97900.0222 To the measurement module connector (b) of the dds (3).
Connect the pressure sensor part no. 552.1.039.1A to the outlet (a) or (c) of cable (4) part no. 97900.0222.
Note
Measure the compression on one cylinder at a time.
On the dds diagnosis instrument (3), select the "measurement module" function by pressing the corresponding icon; then press the "cylinder compression" icon (d) followed by the "start" icon (e).
The socket to which the cable (measurement module) (4) is to be connected is indicated on the screen with a capital letter: a, b or c.
Turn over the engine with the starter motor until the pressure stops rising.
Check the pressure in each cylinder:
An excessively high pressure value can be caused by:
An excessively low pressure value can be caused by:
Refit the spark plugs and position the coil-spark plugs wires (1) in the corresponding compartments and tighten the nuts (2) to a torque of 10 nm (min. 9 Nm max. 11 Nm) (sect. 3 - 3, Frame torque settings).
Refit the tank as indicated in section 8 - 2 "refitting the fuel tank".

system has detected that the battery that
permits the active key (a) to communicate and turn the vehicle on is almost
discharged.
