DETAILS/RESULTS/ACTIONS
TEST CONDITIONS
F2: CHECK FOR BRAKE PEDAL BINDING
1 Check the brake pedal for free operation.
• Did the brake pedal operate freely?
zYe s INSTALL a new brake booster. TEST the
system for normal operation.
zNoINSTALL new brake pedal bushings. TEST
the system for normal operation.
Component Tests
Hydraulic Leak Check
NOTE: There is a common clutch and brake fluid
reservoir, therefore it is possible that a clutch leak
can lead to reduction in the reservoir level.
It is possible that all evidence of fluid leakage may
have washed off if the vehicle has been operated
in rain or snow, as brake fluid is water-soluble.
Refill the system, bleed then apply the brakes
several times. Examine the system to verify that
the reservoir fluid level is actually dropping. Locate
and repair the external leak. If the fluid level drops
and no external leak can be found, check for a
brake master cylinder bore end seal leak.
Brake System Check
Brake Pedal Reserve Check
Where a low brake pedal or the feel of a
bottomed-out condition exists, check for brake
pedal reserve.
1. Operate the engine at idle with the transaxle in the NEUTRAL position.
2. Apply the brake pedal lightly three or four times.
3. Allow 15 seconds for the vacuum to replenish the brake booster.
NOTE: This increased resistance may feel like
something has bottomed out.
4. Apply the brake pedal until it stops moving downward or an increased resistance to the
pedal travel occurs. 5. Hold the brake pedal in the applied position and
raise the engine speed to approximately 2000
rpm.
NOTE: The additional movement of the brake pedal
is the result of the increased engine manifold
vacuum which exerts more force on the brake
booster during engine rundown. This means that
additional stroke is available in the brake master
cylinder and the brake system is not bottoming out.
6. Release the accelerator pedal and observe that the brake pedal moves downward as the engine
returns to idle speed.
Brake Booster Functional Test
Inspect all hoses and connections. All unused
vacuum connectors should be capped. Hoses and
their connections should be correctly secured and
in good condition with no holes and no collapsed
areas. Inspect the check valve on the brake booster
for damage.
Brake Booster Operation Check
1. Check the hydraulic brake system for leaks orlow fluid.
2. With the transaxle in the NEUTRAL position, stop the engine and apply the parking brake.
Apply the brake pedal several times to exhaust
all the vacuum in the system.
3. With the engine turned off and the vacuum in the system exhausted, apply the brake pedal
and hold it down. Start the engine. If the vacuum
system is operating, the brake pedal will tend
to move downward under constant foot
pressure. If no motion is felt, the vacuum
booster system is not functioning.

4. Remove the vacuum hose from the brakebooster. Manifold vacuum should be available
at the brake booster end of the hose with the
engine at idle speed and the transaxle in the
NEUTRAL position. Make sure that all unused
vacuum outlets are correctly capped, hose
connectors are correctly secured and vacuum
hoses are in good condition. When it is
established that manifold vacuum is available
to the brake booster, connect the vacuum hose
to the brake booster and repeat Step 3. If no
downward movement of the brake pedal is felt,
install a new brake booster.
5. Operate the engine a minimum of 10 seconds at approximately 1200 rpm. Stop the engine and
let the vehicle stand for 10 minutes. Then, apply
the brake pedal with approximately 89 N (20 lb)
force. The pedal feel (brake application) should
be the same as that noted with the engine
operating. If the brake pedal feels hard (no
power assist), install a new vacuum check valve
and then repeat the test. If the brake pedal still
feels hard, install a new brake booster. If the
brake pedal movement feels spongy, bleed the
brake system. REFER to: (206-00 Brake System
- General Information)
Brake System Bleeding (General Procedures),
Brake System Pressure Bleeding (General
Procedures),
Component Bleeding (General Procedures).
Brake Master Cylinder
Usually, the first and strongest indicator of anything
wrong with the braking system is a feeling through
the brake pedal. In diagnosing the condition of the
brake master cylinder, check pedal feel as
evidence of a brake concern. Check for the red
brake warning indicator illumination and the fluid
level in the master cylinder reservoir.
Normal Conditions
The following conditions are considered normal
and are not indications that the brake master
cylinder is in need of service.
– Modern brake systems are not designed to
produce as hard a pedal effort as in the past.
Complaints of light pedal efforts should be compared to pedal efforts of another vehicle, of
the same model and year.
– During normal operation of the brake pedal, the fluid level in the reservoir will rise during brake
pedal application and fall during release. The
net fluid level (i.e., after brake pedal application
and release) will remain unchanged.
– A trace of brake fluid will exists on the brake booster shell below the master cylinder
mounting flange. This results from the normal
lubricating action of the master cylinder bore
end seal.
– The fluid level will fall with brake shoe and lining wear.
Abnormal Conditions
NOTE: Prior to performing any diagnosis, make
sure the brake system warning indicator is
functional.
Changes in brake pedal feel or travel are indicators
that something could be wrong with the braking
system. The diagnostic procedure and techniques
use brake pedal feel, warning indicator illumination
and low brake fluid level as indicators in diagnosing
braking system concerns. The following conditions
are considered abnormal and indicate that the
brake master cylinder is in need of service.
– The brake pedal goes down fast. This could be caused by an external or internal leak.
– The brake pedal eases down slowly. This could be caused by an external or internal leak.
– The brake pedal is low and or feels spongy. This condition may be caused by no fluid in the brake
master cylinder reservoir, reservoir cap vent
holes clogged or air in the hydraulic system.
– The brake pedal effort is excessive. This may be caused by a bind or obstruction in the pedal
or linkage, clogged fluid control valve or
insufficient booster vacuum.
– The rear brakes lock up during light pedal force. This may be caused by incorrect tire pressures,
grease or fluid on the brake shoes and linings,
damaged brake shoes and linings, incorrectly
adjusted parking brake, or damaged or
contaminated brake pressure control valves.
– The brake pedal effort is erratic. This condition could be caused by a brake booster malfunction,
extreme caliper piston knock back or incorrectly
installed brake shoes and linings.
– The red brake warning indicator is ON. This may be caused by low fluid level, ignition wire routing

The ABS monitors the different wheel speeds of
the vehicle with the aid of wheel speed sensors.
Using the data from all of the wheel speed sensors,
the ABS module calculates the so-called reference
speed, which is a measure of the actual road
speed. The ABS module compares the individual
circumferential wheel speeds with this reference
speed when the driver initiates braking. If one or
more of the circumferential wheel speeds deviates
too far from the reference speed, this means that
slip at the affected wheels is so great that steering
stability of the vehicle is no longer ensured. The
ABS module actuates electro-mechanical valves
which influence the brake pressure at the relevant
wheels.
Like the traction control system (TCS), the ESP
system uses a large proportion of the ABS
components. In addition, there are sensors which
pick up the steering angle, the acceleration forces
acting on the vehicle and the yaw rate or yaw
moment. The sensors transmit these signals to the
combined ABS/ESP module. Using the wheel
speed and steering angle data, the ABS/ESP
module calculates the direction of travel planned
by the driver and determines the corresponding
speed-dependent lateral acceleration and yaw
moment. These values are compared with those
actual measured. If the actual lateral acceleration
and the yaw moment deviate excessively from the
target values (unstable driving characteristics), the
ABS/ESP module actuates individual brakes
selectively via the HCU (hydraulic control unit). In
addition, the engine speed is reduced by
intervention in the engine management system.
How the system works for understeer: In the
event of understeer, brake intervention occurs at
the wheels on the inside of the curve. The rear
wheel is braked heavily, so that a high amount of slip is caused. In this way, the cornering force of
the rear axle is heavily reduced and the centrifugal
force that now becomes effective turns the rear of
the vehicle back into the curve. The front wheel is
not braked as hard. The braking force that is
transmitted via the front wheel to the road surface
generates a torque with the aid of the lever arm
(vertical tire force to the vehicle's centre of gravity),
which supports the yaw moment of the vehicle.
Both measures together result in the vehicle
reverting back to the curved path intended by the
driver.
How the system works for oversteer:
In the
event of oversteer the wheels on the outside of the
curve are braked. This time, the front wheel is
subjected to a high level of slip so that the
cornering force at the front axle is reduced. The
rear wheel is not braked as heavily and, together
with the effective lever arm, results in a reduction
in the vehicle yaw moment. Both measures
together result in the vehicle being stabilized and
reverting back to the curved path intended by the
driver.
If ESP control occurs, possible ABS interventions
will be overridden as the ESP works at higher slip
rates than the ABS.
Emergency brake assist (EBA): The emergency
brake assist helps drivers in emergency braking
situations by automatically applying the brakes with
the maximum possible braking force.
If the brake pedal is pressed very suddenly, the
ABS module increases the hydraulic pressure to
all of the brakes until the threshold for ABS
intervention is reached. This applies the maximum
braking effort for the available traction. The ABS
control unit monitors inputs from the brake pedal
switch and from the pressure sensor within the

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.

System Operation
Electronic principle of operation
The power steering module requires the following
information in order to ensure precise steering
behavior in all driving situations:
• Steering wheel position
• Rate of turn of the steering wheel
• Vehicle speed
• Information about the vehicle configuration
• Information about the ignition switch position
• Instantaneous engine operating status
The required information is made available to the
power steering module via direct connections and
via the CAN bus (refer to the flow chart).
The steering wheel position and the rate of turn of
the steering wheel are transmitted to the power
steering module as PWM signals from the steering
angle sensor. The steering angle sensor receives
its voltage and ground supply from the power
steering module and operates inductively with an
input voltage of 5 V.
The vehicle speed is made available to the power
steering module as a CAN bus signal from the ABS
module or ESP module. The engine operating status is made available to
the power steering module as a CAN bus signal
from the PCM.
The power steering module obtains the vehicle
configuration information via the CAN bus from the
GEM. This information is required by the power
steering module in order to define the internal
characteristics of the power steering.
The power steering module obtains information
about the current ignition switch position via the
voltage input (terminal 15) of the ignition switch.
Whilst constantly monitoring the relevant input
signals the power steering module accesses stored
maps. With the aid of this information the pump
speed is matched to the current driving situation.
An electronic diagnosis of the electro-hydraulic
power steering can be performed with the aid of a
diagnostic tester via the DLC of the vehicle. For
additional information please refer to "Diagnosis
and Testing" in this section.

In the electrohydraulic power steering system, a
brushless 12 volt direct current motor drives the
hydraulic pump. Higher pumping rates are only
provided when they are required for steering
manoeuvres. This avoids unnecessary energy
consumption in the majority of phases in a drive
cycle.
Commutation in the motor is done electronically.
As a result, there are no brushes to wear away.
The entire system is designed for maintenance-free
operation.
In more than 85% of all driving situations, the
power steering pump operates at standby speed
and consumes less than 4A. However, pump speed
can quickly increase to full rotational speed if
emergency steering manoeuvres require it. The system has a continuously variable pump
rotational speed.
