SC002ENTER INJECTOR CODES
NOTESThis command is run after replacing the injectors and only if the vehicle is IMA
configured (ET104 Injector code use is YES).
If this command is not run, fault DF276 Injector code programming will be present.
Ignition on and engine stopped.
WARNING
The letters J and Q, and figures 0 and 9 are not used in IMA coding.
If these characters are used the entry will be invalid.
Cylinder no. 1 is the cylinder located at the engine flywheel end.
Procedure to be followed:
– Read the 7-character alphanumeric codes engraved on the upper section of the injector body.
– Use command SC002.
– Select the cylinder number concerned in the Desired column, then confirm.
– Enter the injector code noted for the cylinder.
– Enter the new codes for each cylinder, then confirm.
– When the command is completed, the modified codes appear in the Current column.
– Check that the codes correspond to those read earlier.
– If the codes entered appear in neither the Current column nor the Desired column, check the conformity of the
codes read, and make sure the data has been entered correctly.
The possible confusions are:
the figure "1" with the letter "I" and "L",
the figure "2" with the letter "Z",
the figure "5" with the letter "S",
the figure "6" with the letter "G",
the figure "8" with the letter "B".
– Exit fault finding mode.
– Switch off the ignition and wait for the diagnostic tool message (maximum time 8minutes) Communication
lost with computer: EDC16 C36, check the tool connection and computer power supply before switching
the ignition back on.
– Switch the ignition back on and check for faults.
–DF276 Injector code programming should be stored.

Features of the selections: After particle filter regeneration with diagnostic tool and After replacement of the
particle filter:
After using one of these 2 commands:
– switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes): Communication
lost with computer: EDC16C36, check the tool connection and computer power supply.
–Then switch on the ignition again and clear the present or stored faults from the computer memory
(operation to be carried out within 3 minutes of switching on the ignition).
– Check the weight of soot: PR383 Weight of soot in the particle filter.
– If PR383
≥ 1 g. Apply test procedure 12 Manual clearing of the weight of soot.
IMPORTANT
When reinitialising injectors, do not forget that cylinder no. 1 is located at the flywheel end.

VP036INHIBIT FUEL SUPPLY
NOTESThis command enables you to disable the supply to the injectors.
This command is carried out with the engine switched off, and ignition on.
This command allows the injectors to be locked, so that starting is not possible.
Command VP036 allows the engine compressions to be checked in complete safety without disconnecting the
injector connectors or the TDC sensor.
Procedure to follow: (cylinder no. 1 is located on the flywheel end).
– Remove all the heater plugs, connect the compression gauge.
– Position the gear lever in neutral (manual gearbox) or on position P (automatic gearbox).
– Depress the brake pedal and maintain this position.
– Activate command VP036.
– Try to start the vehicle.
– Check the engine compressions.
Start the procedure again on another cylinder.
WARNING
Keep the brake pedal depressed for the length of the test.
Re-establish control of the injectors using command VP037 Stop fuel supply inhibition.

NOTESBefore analysing this customer complaint, check that there are no faults, and the
conformity (or otherwise) of the parameters and statuses, using the diagnostic
tool.
If the customer complaint is not eliminated, perform the following checks.
Check the sealing and condition of the inlet circuit by running Test 4 Turbocharged air circuit check.
Check the low pressure circuit
check the engine parameters:
– Check the update of the engine management computer calibration (last calibration).
– Check the conformity of the IMA codes (using the Identification screen on the Clip diagnostic tool).
– Check the charging circuit (see Technical Note 6014A Checking the charging circuit)
– To check the conformity of the engine speed signal, check:
– The wiring.
– The flywheel position and the condition of the flywheel teeth.
– The position and tightness of the engine speed sensor.
– Check the fuel flow correction from station to station, run Test 10 Poor injector operation.
Check the connections and wiring of the injectors.
Check the connections and wiring of the engine management computer to the injectors.
Repair if necessary.
