SCHEMATIC CIRCUIT DIAGRAM OF NON- ABS BRAKE LINE

General:

Anti lock braking system consists of a Hydraulic

modulator with integrated Electronic control unit,

four wheel speed sensors (one located at each

wheel) and 2 warning lamps in the instrument

cluster (1(yellow for ABS and 1(Red) for EBD).

The brake pipes are connected to the brakes

through the ABS ECU / HCU. They make two

independent circuits diagonally split. The primary

circuit connects the Front Right and the Rear Left

brake while the secondary connects Front Left

and Rear Right brake through ABS unit. Internal

to the Hydraulic modulator each brake has a pair

of solenoid valves, one inlet and one outlet; these

are activated by the ECU to control the brake

force on individual wheels whenever required.
