Parking Aid — Vehicles With: Front Parking Aid
Refer to Wiring Diagrams Section 413-13, for
schematic and connector information.
General Equipment
Ford diagnostic equipment
Principles of Operation
The ultrasonic parking aid system activates when
the ignition switch is turned to the RUN and when
the parking brake is OFF. If a front parking aid
switch is fitted the system will be de-activated and
a light emitting diode (LED) will indicate the state
of the system. A lit LED will indicate that the system
is currently deactivated. The parking aid system
will be disabled if a fault is detected in one of the
four front parking aid sensors, the parking aid
speaker or the parking aid module. An error tone
approximately 3 seconds long will be emitted from
the rear parking aid speaker if a fault is detected.
If the rear parking aid speaker is inoperative the
error tone will sound from the front parking aid
speaker.
Inspection and Verification
1. Verify the customer concern. 2. Visually inspect for obvious signs of electrical
damage.

WARNINGS: Batteries contain sulphuric acid. Avoid
contact with skin, eyes, or clothing. Also,
shield your eyes when working near
batteries to protect against possible
splashing of the acid solution. In case of
acid contact with skin or eyes, flush
immediately with water for a minimum of
15 minutes and get prompt medical
attention. If acid is swallowed, call a
physician immediately. Failure to follow
these instructions may result in personal
injury.
Batteries normally produce explosive
gases which can cause personal injury.
Therefore, do not allow flames, sparks or
lighted substances to come near the
battery. When charging or working near a
battery, always shield your face and
protect your eyes. Always provide
ventilation. Failure to follow these
instructions may result in personal injury.
1. Verify the customer concern.

2. Switch the multimeter to the voltage function.
3. Connect the leads of the multimeter across the
battery terminals.
4. Read the voltage (base voltage).
5. Start the engine.
6. Run the engine at 1500 rpm with no electrical load.
7. Read the voltage. The voltage should be in the range of 14.1 volts to 15.1 volts. If the voltage
increase is less than 2.5 volts above the base
voltage, carry out the Load Test. If the voltage
increase is greater than 2.5 volts, REFER to the
Ford diagnostic equipment. Generator On-Vehicle Tests - Load Test
1. With the engine running, turn on the air
conditioning (if equipped), turn the blower motor
to high speed and the headlamps to high beam.
2. Increase the engine speed to 2000 rpm. The voltage should increase a minimum of 0.5 volts
above the base voltage. If the voltage does not
increase as specified, REFER to the Ford
approved diagnostic tool. If the voltage
increases as specified, the charging system is
charging correctly.

Battery Tester Reading WARNING: Do not recharge the battery.
Make sure that the surface charge was removed. A "REPLACE BATTERY" result could also mean
a poor connection between the battery cables and the battery. Check the connections are OK and
retest. If the result remains the same, INSTALL a NEW battery
REFER to: Battery(414-01 Battery, Mounting and
Cables, Removal and Installation).
REPLACE BATTERY or BAD CELL BATTERY
In addition it is advisable to check the vehicle electrical system. Check that the generator is functioning
correctly and the vehicle does not have an excessive key-off load (in general this should be under
20mA after 40 minutes of key off).

Code
At the end of the test, use the arrow keys to scroll
down the screens to see additional information.
One of these is the TEST CODE.
The TEST CODE has 11 digits, for example:
0021U-B88WKX.
Using the Midtronics GR-590-2 The Midtronics GR-590-2 is both a battery charger
and battery tester and automatically removes the
surface charge as part of the normal operating
procedure.
The Midtronics GR-590-2 can be used on a battery
in-vehicle or out-of-vehicle.
• Disconnect the battery ground cable.
• Connect the positive red clamp from the
Midtronics GR-590-2 to the battery positive

WARNINGS:
Batteries normally produce explosive
gases which may cause personal injury,
therefore do not allow flames, sparks or
lighted substances to come near the
battery. When charging or working near
the battery always shield your face and
protect your eyes. Always provide
adequate ventilation. Failure to follow

the power supply has been disconnected.
Wait for a minimum of 3 minutes before
disconnecting or removing any SRS
components.
Audio unit key code saving devices must
not be used when working on
supplemental restraint or fuel systems.
When using these devices the vehicle
electrical system is still live but with a
reduced current flow. Failure to follow this
instruction may result in personal injury.
CAUTION: Make sure the engine is not
running before disconnecting the battery
ground cable to avoid damage to the
vehicle electrical system.
NOTE: Disconnecting the battery will erase fault
codes, drive values and customer data stored in
the modules.
NOTE: This procedure should be used to
disconnect the battery while carrying out repairs
that refer to the battery being disconnected.
1. Refer to: Battery and Battery Charging Health
and Safety Precautions (100-00 General
Information, Description and Operation).

FORD KUGA 2011.0MY WORKSHOP REPAIR MANUALE103137

Generator
General information
The powertrain control module (PCM) controls the
alternator charging voltage. The connection
between the PCM and the generator is made via
the control module subnetwork (LIN) bus.
If the load on the alternator is high, the PCM can
increase the idle speed.
The alternator is temporarily deactivated during
engine starting so that the engine drag moment is
minimized and it is reactivated again after the
starting procedure.
The PCM controls the charge control lamp in the
instrument cluster via the controller area network
(CAN) bus.
Smart Charge system
In addition to the familiar functions, the Smart
Charge system also performs the following
functions:
•
Automatic deactivation of non-critical high power
electrical consumers when the battery voltage
is low in order to reduce the level of current
drawn.
• Automatic activation of non-critical high power electrical consumers when the battery voltage
is excessively high in order to protect
components which are sensitive to increased
voltages.
The battery charging current is optimized through
continuous calculation of the battery temperature
and monitoring of the alternator output voltage.
By receiving the forwarded alternator load signal,
the PCM is given early warning whenever an
electric consumer is switched on or off. This means
that the PCM receives information about imminent
changes in the torque drawn by the alternator. By
evaluating this information the PCM can provide a
higher level of idling stability.
The two remaining functions of the Smart Charge
System are controlled by the GEM.
Electrical consumers are switched off due to low
voltage when the GEM determines (on the basis
of the message received from the PCM on the CAN
bus via the instrument cluster) that the battery
voltage has dropped below the threshold.
When the threshold for low battery voltage is
reached the GEM automatically deactivates the following consumers - in this order and with a gap
of 5 seconds between each:
• Electric booster heater (vehicles with diesel
engines)
• Heated exterior mirrors
• Heated rear window
• Heated windscreen
If the battery voltage rises back above the lower
threshold then the GEM re-enables all of the
electrical consumers which were previously
disabled. They then have switched off status and
must be switched back on by the driver.
Electrical consumers are switched on due to
excessively high voltage if the GEM determines
that the battery voltage is above the threshold for
overvoltage and the charge control lamp has been
switched on.
When the threshold is reached the GEM
automatically activates the following consumers -
in this order and with a gap of 5 seconds between
each:
• Heated rear window
• Heated exterior mirrors
• Electric booster heater (vehicles with diesel engines)
• Blower motor
If the battery voltage drops back below the
threshold then the GEM automatically deactivates
any consumers that were switched on. However,
if they were switched on by the driver before the
automatic activation, they will then be switched on
again in turn with a 5-second time interval. G964174en
