During braking the ABS function allows the modulation of the braking force effectively applied to each wheel, thus preventing one or more wheels from becoming blocked, which would otherwise cause the loss of control of the vehicle.
The control unit carries out the corrections to the braking by reading the relative speed of each wheel, obtained by special sensors (pick-up).
To guarantee a good signal quality, the distance between the pick-up and the phonic wheel must be between 0.9
÷ 1.0 mm. The electro-hydraulic control unit carries out all the corrections on the braking, using 4 ISO valves and 4
DUMP valves. When an ISO valve is closed, the disc brake calliper is isolated from the hydraulic pump.
The DUMP valve, on the other hand, is used to reduce the pressure of the corresponding disc brake calliper that
is present in the hydraulic circuit. If, during normal use of the vehicle, the ABS warning light on the dashboard is
switched on and the buzzer sounds at the same time, it means that the ABS control unit has found a fault in the
system. When the warning light is on the ABS does not work; this means that in the vehicle the braking system works
anyway, but the electronic control on the braking is deactivated. $%6V\VWHPYDFXXPUHFRYHU\SXPS
The electric vacuum recovery pump is positioned in the front bumper area and is controlled by the MASTER engine injection control unit only with the engine running.
Its operation is determined by a pressure sensor that calculates its drop and makes the pump cut in to maintain the vacuum. Its operation can be checked by means of the LaRa-AS engine control unit “01” Basic setting 8 (109000).

The ESP function (Electronic Stability Program) controls the car’s dynamic behavior during fast cornering; when the
car’s speed and steering are not compatible with traction. In this situation the ESP uses the brake system and engine
torque to maintain the car’s trajectory. 7KH¿JXUHVKRZVWKHEHKDYLRURIDFDUFRUQHULQJDWDFRQVWDQWVSHHG

The electronic control unit governs and activates the various airbag modules and is secured to the car’s tunnel under the console (Fig.1).
The control unit is connected to:• front airbags (driver side airbag module and passenger side airbag module)
• LH and RH side airbags
• LH and RH seatbelt pretensioners
• LH and RH side impact sensors
On the inside, the control unit has: • an electromechanical sensor which discriminates the “activation/deactivation” conditions according to the
vehicle’s longitudinal deceleration;
• an electromagnetic safety sensor operating with the electromechanical sensor; both sensors must enable the
“activation” condition for the system to be deployed;
The electronic control unit analyzes the signals coming from the internal and external sensors (side impact) and,
based on appropriate strategies (which consider the impact’s force and angle), normally activates: • In the case of frontal impact : the driver side airbag module, the passenger side airbag module and the two
seatbelt pretensioners.
• In the case of side impact : the side airbag and the seatbelt pretensioner on the side of the impact.
The control unit has a self-diagnostic feature that checks the entire system’s operation when the ignition key is turned
to “ON”. During the test a red warning light on the dashboard turns on. The warning light turns off approximately four
seconds after the engine is started if the system is working correctly.
