(Normal Mode And ABS Pressure Build-Up Control Function - GF42.30-P-3100GG)
MODEL 463.### ## up to 127356 up to 31.8.01 with CODE (B02) ABS brake system
Braking process in normal mode ABS pressure build-up control mode
(ABS shown on models 463.308/330/331 with 2/2-way valves)
Every ABS control starts with a normal braking process which the driver performs via the brake pedal.
The ABS control module recognizes the braking process via the stop lamp switch and decelerated wheel speeds.
The brake pressure at the front axle is built up via the solenoid valves (y6 and y8). The brake pressure at the rear axle is built up via the solenoid valve (y20).
The pressure is reduced via the same solenoid valves during a normal braking process.
