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).

The two injection control units are identical to each other. They have the same software and hardware.The system recognises the left and right cylinder banks by means of a ground pin on the engine wiring harness.
When writing the immobilizer system, the control unit that will operate as MASTER “01” (A-Fig.1) and the one that
will operate as SLAVE “11” ( B-Fig.1 D U H G H ¿ Q H G

After the immobilizer system is set, you can place the control unit on another vehicle provided it is not locked in the
Fazit system. Once the control unit has been installed on another vehicle after the immobilizer has been set, it is
possible to repeat the exchange procedure only once more.

The “Basic setting” function allows you to make the initial settings on the selected control unit (engine injection).
Default setting: throttle (throttle body) adaptation (Routine 60) (Setting)
1 R W H
Routine 60 is performed when:
• the throttle is adapted
• Engine OFF (on both the MASTER “01” and SLAVE “11” control units).
• Turn the ignition key to ON.
• Connect the computer to the diagnosis outlet OBDII
• Select routine 60 inside the block number ( A-Fig.15).
• Start the connection (
) and press the start push-button ( B-Fig.15).
