System Operation
The HCU features 3 operating modes:
Normal braking:
Initially, no current is supplied to
any of the solenoid-operated valves. Operating the
brake pedal produces a corresponding increase
or decrease of pressure in the brakes, through the
open pilot valves and inlet valves. If the ABS
module determines that EBD is necessary, it
energizes the inlet valves for both the rear brakes,
to isolate the brakes from any further increase in
hydraulic pressure.
ABS braking: If the ABS module determines that
ABS braking is necessary, it actuates the inlet and
outlet valves of the relevant brake and starts the
hydraulic return pump. The inlet valve closes to
isolate the brake from pressurized fluid; the outlet
valve opens to release pressure from the brake
into the accumulator and the return pump circuit.
The brake releases slightly and the wheel starts to turn again. The ABS control unit then operates the
inlet and outlet valves to regulate the hydraulic
pressure acting on the brake in order to maximize
braking effect without the wheel locking up. Control
of the valves for each wheel takes place
individually.
Active braking:
With active braking, pressure is
generated for other braking functions than the
normal and ABS braking systems, e.g. for the ESP
and TCS systems. For active braking, the ABS
module energizes the pilot valves and priming
valves, starts the return pump and energizes all of
the inlet valves. Brake fluid, drawn from the
reservoir through the master cylinder and priming
valve, is pressurized by the return pump and
supplied to the inlet valves. The ABS control unit
then actuates the inlet and outlet valves in order
to regulate the pressure for the individual brakes.
Some noise may be generated during active
braking.

The opto-electronic steering wheel rotation sensors
use light barriers for contactless scanning of a
segment disk which is connected fixedly to the
steering shaft.

Use is made of opto-electronic types of sensors
with relative and absolute steering angle sensing.
For relative steering angle sensing, changes in the
steering angle are measured exclusively by the
sensor and transmitted to the ABS/ESP module.
With the aid of other vehicle status signals (e.g.
wheel speed sensors) the module calculates the
straight ahead position of the steering. For absolute
steering angle sensing, the sensor transmits a
specific signal to the module for each steering
angle position (in relation to one turn of the steering
wheel). The straight ahead position of the steering
is therefore defined in the sensor. On an absolute
steering angle sensor, several photoelectric barrier
modules are distributed around the segment disk
at varying distances. The gaps between segments
of the segment disk are also unequal. For each specific steering angle there is therefore a specific
switch status of all photoelectric barriers.

The HCU comprises the ABS module, the valve
block (with low-pressure accumulators) and the
ABS pump.
The valve block combines all of the brake pressure
control valves in one unit. Depending on the
system, either simple changeover valves or
proportioning valves (e.g. on EBD (electronic brake
force distribution) systems) are installed. The
low-pressure accumulators store the brake fluid
that is returned from the wheel brakes during the
pressure reduction phase until it is drawn back into
the system by the ABS pump.
The ABS pump is designed as a dual piston pump.
This means that two separate pump elements
assure an increase in brake pressure during control
interventions. A direct current motor drives the
pump pistons via an eccentric shaft.
The ABS/ESP module monitors the input signals
of all sensors and actuates the electro-magnetic
brake pressure valves and the ABS pump as
required. For reasons of safety, the module is of
the redundant type, whereby processing of the
signals is carried out via two separate processors
that also monitor each other.

concern is found, correct the cause (if possible)
before proceeding to the next step.
4. If the cause is not visually evident, verify the symptom and refer to the diagnostic tab within
the Ford approved diagnostic tool.
Components Tests
Steering Linkage
1. Grasp the steering wheel firmly and move it upand down and to the left and right without
turning the steering wheel to check the steering
column bearing for wear, steering column shaft
for wear, steering wheel for looseness and
steering column for looseness. If the steering
column bearing or the steering column shaft is
worn install a new steering column. If the
steering wheel or the steering column is loose,
tighten the steering wheel or the steering column
retaining bolts.
2. With the road wheels in the straight ahead position, gently turn the steering wheel to the
left and the right to check for free play in the
steering linkage.
3. There should be no excessive free play at the steering wheel rim. If there is excessive free
play, CHECK the tie-rod inner and outer ball
joints, REFER to Tie-Rod Component Test in
this procedure. CHECK the steering column
universal joint, REFER to Steering Column
Universal Joint Component Test in this
procedure. If there is no free play in the tie-rod
and the steering column, install a new steering
gear.
Tie-Rod
CAUTION: Steering gear boots must be
handled carefully to avoid damage. Use
new steering boot clamps when installing
the steering gear boots.
NOTE: Noises such as knocks, which may appear
to originate from the steering linkage, may also be
generated by front suspension components.

Straight edge
Items to be observed when checking the steering
system
The following list of steering gear conditions and
the methods of testing should be taken into account
when carrying out checks to the steering system:
• If the steering gear has no faults after completing the following checks, do not install
a new steering gear.
• Surface corrosion and marks on the tie-rod are acceptable.
• When checking for turning effort torque peaks in the steering gear, turn the steering wheel from
steering lock stop to steering lock stop in
approximately 15 seconds.
• A steady increase of turning effort torque from steering center to steering lock stop is
acceptable.
• When checking for power steering fluid leaks, turn the steering wheel to the steering lock stop
in approximately 10 seconds.
• Noises from the power steering, for example the power steering pump relief valve, are
acceptable.
STEERING GEAR HOUSING
1. Raise and support the vehicle. REFER to: Lifting(100-02 Jacking and Lifting,
Description and Operation).
2. Visually inspect the steering gear housing for cracks and damage. If the steering gear housing
is cracked or damaged, install a new steering
gear.
REFER to: Steering Gear (211-02 Power
Steering, Removal and Installation).
TIE-RODS
1. Using a straight edge and feeler gauge, check the tie-rods to see if they are straight. If the
distance between the tie-rod and straight edge is greater than 0.5 mm, install a new steering
gear.
REFER to:
Steering Gear (211-02 Power
Steering, Removal and Installation).
2. Check the tightening torque of the tie-rod end to wheel knuckle nut.
REFER to: Tie Rod End (211-03 Steering
Linkage, Removal and Installation).
3. Check the tightening torque of the tie-rod end locking nut.
REFER to: Tie Rod End (211-03 Steering
Linkage, Removal and Installation).
CHECK FOR TURNING EFFORT TORQUE
PEAKS IN THE STEERING GEAR
1. Lower and support the vehicle making sure that the road wheels are just clear of the floor.
2. With the ignition switch in position I, slowly turn the steering wheel from steering lock stop to
steering lock stop. If a turning effort torque peak
or judder is felt while turning the steering wheel,
detach the tie-rods from the wheel knuckles.
3. Slowly turn the steering wheel from steering lock stop to steering lock stop. If a turning effort
torque peak or judder is felt while turning the
steering wheel, install a new steering gear.
REFER to: Steering Gear (211-02 Power
Steering, Removal and Installation).
CHECK FOR POWER STEERING FLUID LEAKS
1. Lower the vehicle.
2. Run the engine at a fast idle and slowly turn the steering wheel to the left-hand steering lock
stop. Hold the steering wheel in this position for
5 seconds with a turning effort torque of 15 Nm
at the steering wheel rim.
3. Turn the steering wheel away from the left-hand steering lock stop for 30 seconds.
4. Run the engine at a fast idle and slowly turn the steering wheel to the right-hand steering lock
stop. Hold the steering wheel in this position for
5 seconds with a turning effort torque of 15 Nm
at the steering wheel rim.
5. Turn the steering wheel away from the right-hand steering lock stop.
6. Check for power steering fluid leaks at the steering gear housing and the power steering
line connections to the steering gear. If there is
