III - ELECTRO-HYDRAULIC UNIT
Discharge the pressure accumulator using the Diag-
nostic tool before any operation on the electro-hy-
draulic unit.
Be careful not to twist the high pressure pipes when re-
moving the electro-hydraulic unit.
IV - GEAR SELECTION SENSOREquipment required
Diagnostic tool
IMPORTANT
Before any operation on the sequential system, dis-
charge the accumulator using the Diagnostic tool.
WARNING
If any operation is carried out on the electro-hydrau-
lic unit, it is essential to clean the unit using a clean-
ing product and compressed air.
Never leave the circuit open and never use a high
pressure cleaner.
WARNING
After the accumulator has been fully filled (15 sec-
onds after the ignition has been switched on): the
oil level is at the MINIMUM mark.
WARNING
To remove the gear selection sensor it is essential
that you shift to first gear before removal.
