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 test point (19) as described below.
Disconnect the wiring connector (f) of pressure switch (1) and remove it taking care to recover the seal.
Insert in the pipe union fitting (2) part no. 875.1.065.1A the fitting (3) part no. 814.1.114.1A, by putting the two copper gaskets (4). Fit in the threaded hole the fitting (3) of pipe (2), by tightening it fully home. Refit on fitting (3) the pressure switch (1), with the relevant gasket and reconnect it to connector (f) of the electric system.
Connect the pressure sensor (5), part no. 552.1.039.1A, to the hose (2), in order to convert the pressure reading into an electric signal.
Turn on the dds diagnosis instrument (6) referring to the paragraph "tester power supply".
Connect the power and diagnosis cable (measurement module) (7) part no. 97900.0222 To the measurement module connector (b) of the dds (6).
Connect the pressure sensor (5) to socket (a) or (c) of the cable (7).
On the dds diagnosis instrument (1), select the "measurement module" function by pressing the corresponding icon; then press the "pressure test" icon (d) followed by the "start" icon (e).
The socket to which the cable (measurement module) (7) is to be connected is indicated on the screen with a capital letter: a, b or c.
Start the engine.
The values may be displayed in three different ways: in one numeric form and in two graphic forms; to select the desired display type, press the "value display" icon.
The measured value is indicated alongside the letter (a) or (c) identifying the cable used for the measurement: i.E. If you used connector (a) of the cable (3), the value measured will displayed next to the letter (a) on the screen.
Oil pressure test values: warm engine
(Minimum oil temperature = 80 C) 1100-1300 min-1
Greater than 0.8 Bar.
3500-4000 Min-1 greater than 4 bar.
Important
The maximum pressure must never exceed 6.0 Bar.
Excessively high pressure may indicate that the relief valve is stuck. Excessively low pressure, on the other hand, may be caused by the relief valve being stuck in the open position, the relief valve spring being too weak, or a faulty oil pump.
Other causes are excessively worn seals and gaskets or a badly worn engine.
Remove the gauges and refit the pressure switch (1) with its seal. Tighten it to a torque of 19 nm +/- 10% (sect. 3 - 3, Frame torque settings).
Connect the electrical system connector (f) to the pressure switch.
Disconnect the dds diagnosis instrument.

Refitting the rear wheel eccentric hub and rear wheel shaft
Refitting is the reverse of removal, with attention to the following points.
If the calliper bracket locating pin (14) was removed, apply the recommended
threadlocker on reassembly.
Tighten the pin (14) to the torque of 33 nm +/- 5% (sect. 3 - 3, Frame torque
settings).

Hands free key (hf) not recognised
The activation of this (amber yellow) "warning" indicates that the hands free
system does not detect the active key (1,
fig.62) Near the vehicle.
Note
Check that the active key (a) is near the vehicle (and has not been lost)
or that it works properly.
