REPLACING THE INJECTORS
After one or more injectors have been replaced, enter the IMA codes again and then run command SC036
Reinitialise programming.
To do this, record the IMA code(s) etched on the injector bodies, and enter the codes into the computer using
command SC002 Enter injector codes, and follow the instructions given by the diagnostic tool. Run command
SC036 Reinitialise programming and select injectors, then follow the procedure. Note:
The "IMA" code (individual injector correction) is a calibration with corrective values unique to each injector,
and is used to adjust their flow accurately (injector classification). This correction takes into account mechanical
variances and the variances of the piezo actuator. An injector's class is determined by measurements taken at
different pressures on a test bench. The IMA class identification (7-character alphanumeric code) is then
engraved on the collar of the injector.
The IMA codes must be read from left to right:
– Foolproofing for reading the IMA codes is carried out using the low pressure return connector and/or the
electrical connector on the injector.
– This reading direction is valid when these connectors are located to the left of the cotech.
The IMA codes are read from left to right (see illustration in MR 402 (Vel Satis ph2), MR 395 (Laguna II ph2),
MR 364 (Mégane II ph2), MR 370 (Scénic II ph2), MR 405 (Espace IV ph2) Mechanical, 13B Diesel injection,
Diesel injector, Removal – Refitting)
Note: When entering characters, confusion can arise between:
– Figure 1 and the letters I and L,
– Figure 2 and the letter Z,
– Figure 5 and the letter S,
– Figure 6 and the letter G,
– Figure 8 and the letter B.
After programming or reprogramming the computer, it is essential to enter the 4 injector codes before confirming
the entry.
These individual corrective values are then written to the computer EEPROM, which can then control the injectors,
taking into account their manufacturing variation.
IMPORTANT:
Engines can only operate correctly if the correct IMA* codes have been entered. If no code has been
entered, or if an invalid code has been entered, fault DF066 Injector code(s) is present and the engine will
run in defect mode (engine speed limited significantly). If another injector's code has been entered, the
system will accept it but will make the wrong correction. This could lead to engine damage, loss of
performance and excessive pollution.
Always use the correct injector codes for the engine cylinder/computer.
Note:
On the M9R engine (Renault - Nissan partnership engine), cylinder no. 1 is located at the timing end.

CP33, check the tool connection and the computer supply.
– Return to fault finding mode.
– select the Identify computer function from the main screen.
– Check that the injector codes entered into the computer correspond to those on the injector bodies.
– If the codes do not match, restart the command SC002 Enter injector codes procedure.
– Check the system faults, and clear any stored faults.
– If the computer does not have any faults, the operation is complete.
If not, deal with the present faults.

being switched on)
Carry out a road test followed by a complete check with the diagnostic tool.
REPLACING THE HEATER PLUGS (Vdiag 20, 24, 38 and 74 only)
SLOW plugs are identified by a black ring.
FAST plugs are identified by a white ring.
After replacing the heater plugs with plugs of a different type, reconfigure the type of plugs fitted on the vehicle.
Carry out the following steps:
– switch on the ignition,
– run command SC036 Reinitialise programming,
–select Heater plugs as the operation type and follow the instructions,
–switch off the ignition and wait for the diagnostic tool message (maximum wait 8 minutes): Loss of dialogue

Check the condition of the coolant temperature sensor connector (see Wiring Diagram Technical Note, Laguna
II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 244).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Measure the resistance between connections 3C and 3JK of component 244.
If the resistance is less than 87 Ω, replace the sensor
Check the insulation to earth of the following connections:
•3C and 3JK between components 120 and 244.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
If the fault is still present, contact the Techline.
