206-09A-3 Anti-Lock Control 206-09A-3
DESCRIPTION AND OPERATION
Anti-Lock Control
Overview
Function
The ABS is a closed loop control system in the
brake system which prevents the wheels from
1 4 1 Ignition lock I situations.
3
1 5 1 Stoplamp switch I
6 ABS warning lamp in the instrument
I 1 cluster
Wheel
speed sensors
In addition to the conventional brake system with
two diagonally split brake circuits, the ABS consists
of an ABS hydraulic unit with integrated control
unit, four wheel sensors and the ABS warning lamp
in the instrument cluster. locking up under
braking and therefore maintains
steerability and driving stability in extreme
Electronic brake force distribution is integrated in
the software of the ABS control unit', which
electronically regulates and optimises the pressure
applied to the wheel brakes on the front and rear
axles in accordance with the operating conditions.
ABS control unit
The ABS control unit continuously compares stored
physical deceleration values with those detected
by the wheel sensors. This allows the lock-up
tendency of each wheel to be detected separately.
If the ABS control unit detects that a wheel is
threatening to lock up, then the corresponding
hydraulic valves in the valve block are either closed
or opened.
The ABS control unit then also passes on the
vehicle speed signal obtained from the wheel sensors to the Powertrain Control Module (PCM).

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.
