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. $ % 6 V \ V W H P Y D F X X P U H F R Y H U \ S X P S
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).
