tire pressure FORD KUGA 2011 1.G Owner's Manual

HCU to check for sudden actuation of the brakes.
With the brake pedal pressed, the ABS module
triggers emergency braking if the rate of increase
of hydraulic pressure exceeds the predetermined
limit.
If the brake pedal is pressed so hard that the ABS
becomes active on the front wheels then the ABS
control unit increases the pressure to the rear
wheel brakes up to the ABS intervention threshold.
EBA operation continues until the driver releases
the brake pedal sufficiently for the hydraulic
pressure in the HCU to drop below a threshold
value stored in the ABS module.
Trailer stability control:If the vehicle is ordered
with a trailer coupling then the Trailer Stability
Control function is integrated in the ESP. The ESP
detects snaking when driving with a trailer and
reduces the speed of the vehicle and trailer through
adapted braking and, if necessary, by also reducing
the engine output until the snaking movement of
the trailer is corrected.
Roll-over protection: The ESP dynamically
determines the tipping tendency of the vehicle and
works in conjunction with the EBA system to
prevent the vehicle from tipping over during
dynamic maneuvers like lane changing or while
negotiating bends.
Emergency brake light: The emergency brake
light automatically switches on the hazard flasher
system to warn drivers of other vehicles that
emergency braking is being initiated. Based on a
defined delay value, the ABS/ESP module sends
a signal to the generic electronic module (GEM)
via the CAN data bus. The GEM activates the
hazard flasher system, that then flashes 7 times.
Prerequisites for activation of the emergency brake
light are:
• The speed is higher than 50 km/h.
• The brake pedal is being actuated.
• The deceleration is greater than 9 m/s².
To prevent activation on snow or ice, for example,
the following prerequisites must be met:
• The speed is higher than 50 km/h.
• The brake pedal is being actuated.
• ABS regulation takes place.
• The deceleration is greater than 6 m/s².
Tire pressure monitoring system: The tire
pressure monitoring system used in the Kuga is
able to detect loss of air in a tire at an early stage
and warn the driver. Because it can only compare
the behaviour of the tyres with each other, it is not possible to draw conclusions about the absolute
tyre pressure. It is also not possible to monitor the
spare tyre pressure. In order for the system to
operate correctly, the tyre pressures must be
regularly checked and corrected and the system
subsequently initialised (see below).
The tire pressure monitoring system used here,
depending on the equipment level, is built into the
anti-lock braking system (ABS) as an extra function
and therefore does not have its own sensors.
The ABS module measures the loss of pressure
in the tyres by calculation using the wheel speed
sensors of the ABS system. If a tyre loses
pressure, its diameter decreases and the speed of
the wheel therefore increases. If the ABS module
detects such a loss in pressure, it sends a signal
to the instrument cluster via the CAN bus and a
warning message is displayed in the message
centre. The warning threshold depends among
other things on the dimension of the tyres being
used, the vehicle operating conditions and the
status at the last initialisation. Since neither the
absolute tyre pressure nor the position of the tyre
is known, the pressure of all the tyres must be
checked and the system re-initialised after a tyre
pressure warning. If necessary, the cause of the
loss of pressure must be investigated.
Regular tyre pressure checks are still necessary.
The system must be initialised after a tyre is
changed, winter or summer tyres fitted, the
pressures corrected or adjusted to suit the vehicle
load. This can be done by the driver using the
driver information system. For further information,
see: Owner’s Manual.

actuated) or opened (actuated). Each cylinder has
its own injector. The injection is accurately dosed
and takes place at a time determined by the PCM.
Injection takes place immediately in front of the
intake valves of the cylinder. The injectors are
actuated ground side via end-stages integrated
into the PCM and using the signal calculated by
the engine management system. Power is supplied
via the Powertrain Control Module relay in the BJB.
The injected fuel quantity depends on the opening
time, the fuel pressure and the diameter of the
nozzle holes.
The fuel metering is determined via open or
closed-loop control.
The open control loop differs from the closed
control loop in that the lambda control is
deactivated.
The PCM switches from closed to open-loop control
if the HO2S cools down to below 600°C or fails, as
well as when accelerating, coasting and at full load.
Regulation of injected fuel quantity via the PCM
involves:
• controlling the fuel pump,
• calculating the required quantity of fuel forengine starting,
• observance of the desired air/fuel ratio,
• calculating air mass,
• and calculating the fuel quantity for the different operating states and corresponding fuel
adjustment measures.
Open loop control
Open loop control is used primarily for fuel
injection, as long as the signals of the HO2S are
not involved in the calculation of the PCM.
The two most important reasons that make it
absolutely essential to run the engine without
lambda control (open-loop control) are the following
operating conditions:
• Cold engine (starting, warm-up phase)
• Full-load operation (WOT (wide open throttle))
Under these operating conditions the engine needs
a rich air/fuel mixture with lambda values below λ
= 1 in order to achieve optimum running or
optimum performance.
It is possible to keep this unregulated range very
small by using a broadband HO2S.
Closed-loop control
Closed loop control ensures strict control of
exhaust emissions in conjunction with the TWC (three-way catalytic converter) and economical fuel
consumption. With closed loop control, the signals
from the HO2S are analyzed by the PCM and the
engine always runs in the optimum range of λ = 1.
In addition to the normal HO2S, the signal from the
monitoring sensor for the catalytic converter is also
included in the control. The lambda control is
optimized on the basis of this data.
Certain factors such as wear, component
tolerances or more minor defects such as air leaks
in the intake system are compensated for by
lambda control. If the deviation occurs for a longer
period of time, this is recorded by the adaptive
(self-learning) function of lambda control. In this
instance, the entire map is shifted by the
corresponding amount, to enable control to
commence once again from the virtual baseline.
These adaptive settings are stored in the PCM and
are also used in open-loop control conditions.
If the adaptive value is too high or too low, an error
is stored in the fault memory of the PCM.
Oxygen sensor (HO2S) and catalyst monitor
sensor
A broadband HO2S is used as the HO2S. The
HO2S is located in front of the TWC. The catalyst
monitor sensor is located in the center of the TWC
so that it can detect any deterioration in the
cleaning performance of the TWC more quickly.
The HO2S measures the residual amount of
oxygen in the exhaust before the TWC.
The catalyst monitor sensor measures the amount
of oxygen in the exhaust gas after or in the TWC.
Both the HO2S and the catalyst monitor sensor
transmit these data to the PCM.
The broadband HO2S works at temperatures of
between 650°C and 900 °C. If the temperature
rises above 1000°C, the oxygen sensor will be
irreparably damaged.
To reach optimum operating temperature as quickly
as possible, an electrically-heated oxygen sensor
is installed. The heating also serves to maintain a
suitable operating temperature while coasting, for
example, when no hot gases are flowing past the
oxygen sensor.
The heating element in the HO2S is a PTC
(positive temperature coefficient) resistor. The
heating element is supplied with battery voltage as
soon as the Powertrain Control Module relay
engages. The HO2S is earthed via the PCM. As
the heating current is high when the element is
cold, it is limited via PWM in the PCM until a certain

Knowing and Understanding Customer
Concerns
Knowing and understanding customer concerns is
necessary in order to perform diagnosis.
First of all, ask the customer under which operating
conditions the problem occurs. If possible, try to
reproduce the concern by road testing the vehicle
with the customer.
You should be familiar with the following operating
conditions:
• Engine operating state
– Cold, warm-up phase, or at operatingtemperature
• Ambient temperature – Below 0 °C (32 °F), 0 to 20 °C (32 to 68 °F),or above 20 °C (68 °F)
• Road conditions – Good, poor, or off-road
• Vehicle load status – Unloaded, loaded, or fully loaded
• Transaxle status in manual mode – Upshift, downshift, overrun or acceleration
Testing Possible Causes of Transmission
Control Faults
Before performing a symptom-based diagnosis,
first carry out checks to eliminate various other
potential causes of the fault.
These situations include:
• Battery state of charge
• Defective fuses • Loose or corroded cables or electrical
connectors
• Ground connections to the transmission
• Retrofitted add-on units which are not approved by Ford, such as air conditioning, car telephone,
cruise control
• Unapproved tire sizes
• Incorrect tire size programmed with IDS (Integrated Diagnostic System)
• Engine tuning
IDS Diagnosis
NOTE: Customer concerns relating to the transaxle
can also be caused by engine-related faults.
The transmission control system of the AW55 is
closely linked to the engine management system.
Faults in the engine management system may
affect the transmission control system.
Before repairing the transaxle, it should be ensured
that the fault is not caused by the engine
management system or other non-transaxle
components.
The diagnosis can be performed on the AW55 with
the aid of von IDS.
visual inspection
A thorough visual inspection of the transaxle is
necessary for successful diagnosis.
A visual inspection is made of the following
components:
• Connectors and plug connections
• Ease of operation of the selector lever
