GF42.35-P-3000B ETS, ABS control mode, function
- with CODE (212a) Electronic Traction System (ETS)

Component Identification:

ABS control mode - pressure reduction
The control process or valve positions shown in the example relate to the FR brake.

The ETS control module introduces the pressure reduction phase from the slip values of the braked wheels.

The pressure reduction phase is introduced by actuating (opening) the solenoid valve (y9). The solenoid valve (y8) remains actuated in this control phase (closed). -
During the pressure reduction phase brake fluid flows back into the high pressure/return pump (p1) via the accumulator. From there the high pressure/return pump in pressure circuit 2 delivers the brake fluid back into the master brake cylinder against the prevailing pressure. A silencer (10) is fitted to each brake circuit to dampen delivery noise.
