IMPORTANT
☞
•
In case of damage to the gear clutch pressure sensors,
the system does not engage the clutches corresponding
to the damaged sensors. In case of damage to the 2
nd
and
3
rd
gear clutch pressure sensors, the system passes auto-
matically from the automatic logic AU to the semiautomat-
ic logic SA.
•
Engine start:
In case of damage to the 2
nd
gear solenoid valve, the elec-
tronic control takes the 1
st
gear as point of reference. In
case of damage to the 2
nd
or 3
rd
gear solenoid valve, the
system passes automatically from the automatic logic AU
to the semiautomatic logic SA.
•
In case of damage to the RPM sensor, the shifting with the
automatic logic AU cannot take place any more.

When a figure code appears on the display, contact your
