2011 FORD KUGA pressure

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.

Turning Effort Test
NOTE: Before carrying out this test, make sure
that the suspension components are serviceable.
NOTE: Before carrying out this test, make sure
that the steering column is serviceable.
NOTE: Before carrying out this test, make sure
that the toe adjustment and tire pressures are
correct.
1. Park the vehicle on a dry, even surface and apply the parking brake.
2. Remove the driver air bag module.
REFER to: Driver Air Bag Module (501-20
Supplemental Restraint System, Removal and
Installation).
3. Connect the air bag simulators to the sub-harnesses in place of the driver air bag
module at the top of the steering column.
4. Start the engine and turn the steering wheel from lock to lock several times until the power
steering fluid has reached normal operating
temperature. 5. Using a suitable torque wrench and socket,
check the steering wheel turning effort.
6. If the steering wheel turning effort is greater than the specification, install a new steering gear.
Steering Column Universal Joint
1.WARNING: Install a new steering column
to steering gear pinion retaining bolt. Failure
to follow this instruction may result in
personal injury.
Detach the steering column from the steering
gear pinion.• Discard the steering column to steering gear pinion retaining bolt.
