System Operation
General
In a communications network (data bus system),
various modules of different systems are connected
to one another via one or several lines.
The data bus system is used exclusively for
transmitting data between the connected modules,
as well as between the connected modules and
the Ford diagnostic unit.
In a data bus system, complete data blocks are
transmitted instead of single on/off pulses. In
addition to the actual information, these data blocks
also contain data regarding the address of the
module to be addressed, the size of the data block
and information for monitoring the content of each
individual data block.
Data bus systems offer various advantages: • Simplified data transmission between the
modules due to a standardized protocol
• Fewer sensors and connectors
• Improved diagnostic options
• Lower costs
The DLC is connected to the various data bus
systems and to the power supply via the standard
16-pin GEM. The signal for the module
programming is also transferred via the DLC.
In a data bus system, if there is a break in one or
both lines or there is a short to ground or to voltage,
then communication between the modules and
with the Ford diagnostic unit is disturbed or is no
longer possible at all.
In order to be able to establish communication with
one another, the modules of the individual systems G1030779en

Engine - Oil Leaks
NOTE:
Before installing new gaskets or oil seals,
make sure that the fault is clearly established.
If the oil leak cannot be identified clearly by a visual
inspection, carry out an ultraviolet (UV) test:
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.
