REPLACING THE INJECTORS
After replacing one or more injectors, re-enter the IMA codes.
The system must be configured via the diagnostic socket using the RENAULT CLIP diagnostic tool.
→ PROCEDURE to be followed after one or more injectors are replaced:
IMPORTANT
Cylinder no. 1 is located at the engine flywheel end.
–make a note of the IMA code(s) engraved on the injector body,
–enter these codes in the computer using command SC002 Enter injector codes, then follow the instructions given
by the diagnostic tool,
–once the command has finished,
–switch off the ignition,
–wait 1 min before switching on the ignition again,
–return to fault finding mode,
–select the Computer identification function from the main screen,
–check that the injector codes entered into the computer match those found on the bodies of the injectors:
–if the codes do not match, repeat the procedure for command SC002 Enter injector codes;
–if the codes do match, check system faults and clear any stored faults;
–if there are faults, deal with the present faults,
–clear the faults from the computer memory.
Carry out a road test followed by a complete check with the diagnostic tool.
End of operation.Note:
The IMA coding (individual injector correction) is a calibration made in production on each injector to adjust
the flow accurately.
These correction values are etched onto the Bakelite body of each injector (6 alphanumeric characters) and then
entered into the computer which then controls each injector 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, the fault DF276 Injector code
programming, is present and the engine will be in defect mode (speed heavily limited).
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.
