ELECTRICAL POWER
STEERING SYSTEM
IMPORTANT The electrical
power steering system only works
when the ignition key is at MAR.
A new electrically controlled power
steering system called EPAS (Electri-
cal Power Assisted Steering) is fitted
in the Fiat 600.
The EPAS system is operated by an
electric motor and consists of only
two parts: a steering column with
built-in electric motor and an elec-
tronic control unit.
The control unit processes the data
from the various sensors located in
the car and converts the signals into
commands for the power steering
motor to reduce the effect on the
steering wheel both when parking and
when cornering.
