use, they must be thrown away (once used they are soiled and cleaning is not sufficient to make them
reusable). Unused plugs must be thrown away.
Ensure that you have hermetically resealable plastic bags for storing removed parts. There is less risk of
parts stored in this way being exposed to contamination. The bags must be used only once, and after use
they must be thrown away.
Ensure that lint-free towelettes are used for injection pump related service purposes. The use of a normal
cloth or paper for cleaning purposes is prohibited. They are not lint-free and may contaminate the fuel cir-
cuit of the system. A lint-free cloth should only be used once.
Instructions to Be Followed before Opening The Fuel Circuit:
Use new thinner for each operation (used thinner contains impurities). Pour it into a clean receptacle.
For each operation, use a clean brush in good condition (the brush must not shed its bristles).
Use a brush and thinners to clean the connections to be opened.
Blow compressed air over the cleaned parts (tools, cleaned the same way as the parts, connections and injec-
tion system zone). Check that no bristles remain adhering.
Wash your hands before and during the operation if necessary.
When wearing leather protective gloves, cover them with latex gloves.
Instructions to Be Followed During The Operation:
As soon as the circuit is open, all openings must be plugged to prevent impurities from entering the system.
The plugs to be used are available from the Parts Stores. They must not, under any circumstances, be reused.
Close the resealable bag, even if it has to be reopened shortly afterwards. The ambient atmosphere carries
impurities.
All components removed from the injection system must be stored in a hermetically sealed plastic bag once
the plugs have been inserted.
The use of a brush, thinner, bellows, sponge or normal cloth is strictly forbidden once the circuit has been
opened.
These items are likely to allow contaminants to enter the system.
A new component replacing an old one must not be removed from its packaging until it is to be fitted to the
vehicle.
ECM REPLACEMENT, PROGRAMMING OR REPROGRAMMING OPERATION
Following items can be (re)programmed via the DLC using the CONSULT-II.
System configuration
Injector adjustment value
Before replacing the ECM in after-sales operations, the following data must be readout using CONSULT-II:
The injector adjustment values to be noted to appropriate paper or CONSULT-II copying function.
NOTE:
The injector adjustment value for each fuel injector must be entered manually after the ECM has been
replaced or (re)programmed by reading the injector adjustment value on each fuel injector.
IMPORTANT: It is not possible to test an ECM from the parts stores because it cannot be fitted to any other
vehicle.
REPLACING THE INJECTORS
NOTE:
The injector adjustment value is a calibration made on each fuel injector in the factory in order to adjust its flow
precisely.
These injector adjustment values are written on a label affixed to each fuel injector then entered into the ECM
which then controls each fuel injector taking into account its individual manufacturing variations.
When replacing one or more fuel injectors, the parameters of the fuel injector output concerned must be mod-
ified. The system can be configured using the CONSULT-II.
