206-09A-4 Anti-Lock Control 206-09A-4
DESCRIPTION AND OPERATION
The warning lamp in the instrument cluster is
actuated by the ABS control unit after switching on
the ignition. It remains on up to the end of the ABS
self-test, and is also actuated in the event of
system errors.
It continuously monitors the system for possible
faults and stores these as and when they occur.
The corresponding trouble codes can be
interrogated with the aid of WDS via the DLC
.
The ABS control unit is directly connected via a
diagnostic data link to the DLC.
Valve block
The valve block contains four inlet valves and four
outlet valves. There is one inlet valve and one
outlet valve for each wheel.
When there is no electrical supply the inlet valves
are open and the outlet valves are closed.
The valve block also contains the low-pressure
reservoir and sound damping chambers.
Pump motor
In the event of an ABS intervention the pump motor
ensures that the pressure can be provided to the
regulating channels independently of the brake
master cylinder.
ABS regulating cycle
An ABS regulating cycle has three phases:
Phase
1 - holding pressure
The inlet valve is closed, and the brake pressure
to the wheel brake cannot be increased any
further, even if the actuation pressure (brake
pedal) is increased further.
Phase
2 - pressure reduction
The outlet valve is temporarily opened, and the
brake pressure to the wheel brake is reduced
in a controlled manner.
Phase
3 - pressure build-up
The inlet valve is opened in stages, and the
brake pressure is increased in a controlled
manner to achieve the greatest possible
deceleration.

206-0949-5 Anti-Lock Control 206-09A-5 -- -
DESCRIPTION AND OPERATION
Anti-Lock Control
MK70 Anti-lock Brake System (ABS)
The MK70 ABS is similar to the MK60 in
construction and design. The main differences are:
New ABS control unit
New hydraulic lines through a revised valve
block
New wiring harness and electrical connector
(fewer occupied pins)
The MK70 ABS system will be installed from
0512004 in vehicles which only have one ABS
function.
Vehicles with
ESPlBrake Traction Control System
(BTCS) will continue to be equipped with the
MK60.
MK60 ABS
Item Description
Fpump motor I
1 2 I Valve block I
1 3 1 ABS control unit I
The MK60 ABS has been designed specifically for
small to medium size vehicles. Compared to the
MK20 ABS system, it has been possible to reduce
the size of the hydraulic and electric components
(e.g. hydraulic valves and solenoids) and the
housing.
As a result, the overall weight of the ABS hydraulic
unit has been significantly reduced.
The hydraulic unit consists of the pump motor, the
valve block with
8 hydraulic valves and the
electronic control unit.
The ABS control unit actuates the ABS warning lamp in the instrument cluster via the CAN
databus.
The MK60 ABS is a 413 system. This means that
the wheel speed is measured individually for each
wheel (4 wheel speed sensors).
ABS controlled braking is provided individually for the front wheels and jointly for the two rear wheels
(3 control channels; select-low control), i.e. the
ABS control for the rear wheels is governed by the
wheel closest to locking up.
