THE ANTI-LOCK BRAKING SYSTEM
The system is composed of an electronic control unit which
processes signals received from sensors placed near each
wheel, a solenoid-valve group which regulates the brake-fluid
pressure in the hydraulic circuits and a pump with accumulator
which keeps the brake fluid at high pressure.
The signals sent by the tour sensors are processed by the
electronic control unit and. if ore or more wheels tend to lock
when braking, the unit acts upon the solenoid-valve group to
adjust the bra<e-fluid pressure in the part of the hydraulic
circuit involved.
The pump-accumulator group serves to keep the brake fluid at
a high pressure to ensure rapid modulation of the braking
pressure.
When the engine is started, the electronic control unit also
performs a two-second self-diagnosis routine on the whole
system, shown by the appearance of the indicator light 1
If all the parameters tested are acceptable, the light 1 switches
off; if there is an anomaly in one cr more system components, it
remains lighted.
If the indicator light remains lighted, or comes on during dnv
ing, you need not slop the car; just go loan Alta Romeo Service
Dealer as soon as possible. Even if the ABS system is shul oft
following self-ciagnosis (lighting of indicator light 1 after the
two-second routine or when driving), the power-assisted brake
system will continue to provide the powerful, dependable brak¬
ing action typical of an Alfa Romeo.
Caulion.
Should the ABS trooWt iridic-aior light 1 op ar the
same time as Ihe low-brake-fluid/worn-brake-pad indicator
(indicator light 2) on the Alfa Romeo Control, slop the car
Immediately without depressing the brake pedal violently ana
go to the nearest Alfa Romeo Service Dealer.
