starter relay FORD KUGA 2011 1.G Workshop Manual

Electrical consumers are switched off when the
battery voltage is low if the GEM determines (as a
result of the message received from the PCM on
the CAN bus via the instrument cluster) that the
battery voltage has dropped below the threshold
value.
When the threshold for low battery voltage is
reached the GEM switches off the following
consumers in this order at intervals of 5 seconds:
• Heated windscreen
• Heated rear window
• Electric booster Heater
• A/C system
If the battery voltage increases back above the
lower threshold then all of the consumers which
were previously switched off are reactivated by the
GEM.
Once the electric consumers have been reactivated
their status is "switched off", i.e. the consumers
are switched off and await an input signal provided
from the relevant switch via the GEM; this means
that the driver needs to switch these components
back on again.
Electrical consumers are switched on when the
battery voltage is excessively high if the GEM
determines that the battery voltage has increased
above the threshold for overvoltage and the
charging system warning indicator has come on.
When the threshold is reached the GEM switches
on the following consumers in this order at intervals
of 5 seconds:
• Heated windscreen
• Heated rear window
When these components are deactivated again
their status is "switched off". This means that the
consumers are waiting for an input signal provided
from the relevant switch via the GEM.
Ignition overload protection
The ignition overload protection intermittently
disconnects certain circuits in order to restrict the
current being drawn from the battery while the
starter motor is operating.
The position of the ignition switch is broadcast by
the instrument cluster on the medium speed CAN
bus.
The ignition overload protection relay which is
integrated in the battery junction box is activated
by the GEM if the message "ignition switch in
position III" is received from the instrument cluster.
All of the electric consumers controlled by the
ignition overload protection relay are then switched
off.
The following consumers (among others) are
controlled by the ignition overload protection relay:
• Fog lamps
• Windscreen/rear window wash/wipe systems
• Backup lamps
• Heated washer nozzles
• Heating blower motor
• Seat heating
Headlamp switch-off delay
The headlamp switch-off delay utilizes the low
beam together with the peripheral lights (if
equipped) to illuminate the area surrounding the
vehicle. The function is activated by operating the
high beam lever when the ignition switch is in the
"0" position.
After the last door has been closed, the function
remains active for a further 30 seconds and then
switches off automatically.
When a door or the tailgate is open, the switch-off
time is extended to 180 seconds. After the last door
has been closed, the switch-off time is reset to 30
seconds.
The headlamp switch-off delay can be deactivated
prematurely by operating the high beam lever again
or by switching on the ignition.
The switch-off time is adjusted to set values at the
factory and cannot be re-programmed using the
Ford diagnostic unit.

Ultraviolet (UV) Testing
1. Clean the engine and transmission with a suitable cleaning fluid.
2. Pour the UV-test fluid in accordance with the quantity specified by the manufacturer through
the oil filler neck into the engine and install the
oil filler cap.
WARNING: Vehicles with manual transaxle,
shift the transaxle into Neutral. Failure to
follow this instruction may result in
personal injury.
3. Start the engine and let it run for about five minutes.
4. Switch off the engine.
NOTE: If no leak can be found, road test the
vehicle under various loads and check the engine
for leaks again.
5. Check the engine for oil leaks using a suitable UV lamp.
6. Rectify any leaks found and check the engine for oil leaks.
Measure the compression pressure
NOTE: The powertrain control module (PCM)
receives an error message when the fuel pump
relay is removed or electrical components are disconnected. This error message must be deleted
from the fault memory using the Ford diagnostic
equipment after completing the compression test.
NOTE:
Valve clearance must be set correctly
before performing a compression test. Make sure
the engine is at the normal operating temperature.
NOTE: The varying design of compression
checking devices and fluctuating starter motor
speeds normally only allows for a comparison to
be made of the compression pressures in all
cylinders.

System Operation
Smart Start
The PCM enables the starting process when a key
providing a valid code is read via the PATS. This
code is then verified in the GEM and compared
with the saved code. If this code is recognized as
correct, synchronization with other modules is
carried out. After successful synchronization, the
engine is cleared to start in the PCM. The PCM
connects earth to the starter relay, which then
connects power to the starter solenoid. As soon
as the engine reaches a certain speed, the PCM
disconnects the starter relay and so turns off the
starter. This protects the starter.
If the engine does not turn or turns only slowly, the
starting process is aborted by the PCM.
The starter is notactivated if:
• the engine is running (i.e. the engine speed is above a particular value),
• the PATS does not permit the engine to be started,
• the clutch pedal is not operated (vehicles with manual transmission),
• the gear selector level is not set to P or N (vehicles with automatic transmission),
• the brake pedal is not operated (vehicles with automatic transmission).
Emergency starting function
If the keyless vehicle system is unable to recognize
the passive key, the vehicle can be started via the
emergency starting function. In this case, there is a passive key mount on the
steering wheel. A PATS transmission/reception
unit is attached to this.
To start the engine, the passive key must be
inserted into the passive key mount. The Start/Stop
button can then be used to turn on the ignition and
start the engine as normal. To deactivate the
PATS, a transponder is fitted in the passive key,
which is read by the transmission/reception unit.

System Operation
The engine is controlled by the PCM. For this
purpose, the PCM uses information from the
sensors, sender units and switches. In addition,
the PCM receives information from other control
modules via the CAN data bus. All the information
is processed in the PCM and is used to control or
regulate the different actuators.
These are:
• the throttle control unit,
• the fuel injectors, • the camshaft adjustment,
• the boost control solenoid valve
• and the ignition coils.
Some values are sent via the CAN databus to other
systems.
The following functions are regulated or controlled
by the PCM:

FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL

• Starting process
• Engine running– Fuel supply to the engine including lambdacontrol
– Ignition setting including knock control
– Idle speed control
– Boost pressure control
– Valve timing via the camshaft adjuster for the intake and exhaust camshafts (including
internal exhaust gas recirculation)
• Refrigerant compressor (activation, deactivation and delivery)
• EVAP purge valve
• Charging system
Fuel is supplied to the engine via a sequential
multi-point injection system. Ignition is performed
by a distributor-less ignition system with one
ignition coil unit for each cylinder.
The PCM optimizes engine power and emissions
at all times by processing the sensor signals and
information received via the CAN databus and
using these for open or closed loop control of the
different variables.
The PCM contains part of the PATS (passive
anti-theft system).
The PCM is supplied with battery voltage via a fuse
in the BJB (battery junction box). This power supply
is needed to ensure that saved data is not lost
when the engine is switched off.
For other power supply requirements, the PCM
switches on a relay in the BJB which is responsible
for supplying power to the PCM and to some
sensors and actuators. Each of these are protected
by fuses in the BJB.
To guarantee optimum engine running at all times,
the PCM has several adaptive (self-learning)
functions. These adapt the output signals to
changing circumstances, such as wear or system
faults.
In some cases a faulty signal is replaced with a
substitute value or limited. A substitute value can
be calculated from other signals or it can be
predefined by the PCM. The substitute value allows
the vehicle to keep on running without the emission
values changing unduly. Depending on the signal
failure, the PCM operates in emergency mode. In
this mode, the engine power and/or the engine
speed is reduced to prevent further damage.
Depending on the faulty signal, a fault code is
stored in the error memory of the PCM. These can be read out using IDS (Integrated Diagnostic
System) via the DLC.
The PCM processes and evaluates the signals
from the sensors. The following sensors send
signals to the PCM:
• CMP sensors
• CKP sensor
• MAF sensor
•KS
• ECT sensor
• TP sensor
• APP sensor
• Broadband HO2S
• Catalyst monitor sensor
• MAPT sensor
• Air conditioning (A/C) pressure sensor
• Alternator
• Fuel temperature and fuel pressure sensor
• Engine oil level, temperature and quality sensor
• Outside air temperature sensor
The following components receive signals from the
PCM:
• Powertrain Control Module relay
• A/C clutch relay
• injectors
• Direct ignition coils
• Cooling fan module
• Throttle control unit
• Camshaft adjuster solenoid valve
• Starter Relay
• EVAP purge valve
• Alternator
• Heating element - broadband HO2S
• Catalyst monitor sensor heating element
• FPDM
• Wastegate control valve
• Air conditioning compressor
The PCM receives the following signals via the
CAN databus:
• APP
•CPP
• BPP
• Vehicle speed.
• Refrigerant compressor request
• PAT S
