Injector Programming
The purpose of this function is to enable the technician to replace a faulty injector, or
injectors, and program in the value of the new injector to the Diesel Control Unit.
It may also be used when a new Control Unit has been installed and the technician is
required to program it with the values of the injectors fitted.
The function is available on most of the following Engine Management Systems:
• Bosch EDC15C3, fitted to 1.9 DCi and 2.2 DCi engines.
• Bosch EDC16, fitted to 1.9DCi and 2.0DCi engines.
• Delphi Lucas LVCR, fitted to 1.5 DCi engines.
• Delphi Lucas DDCR, fitted to 1.5 DCi engines.
Injectors are classified in the factory according to their respective flow: at idle speed,
when fully charged or in the pre-injection phase.
For the Bosch systems a 6-digit alphanumeric code is engraved on the Injector
indicating the classification. For the Delphi Lucas systems a 16-digit alphanumeric
code is engraved on the Injector indicating the classification.
The code for each injector is stored in the memory of the ECU, enabling the ECU to
control each injector taking into account the variations in their manufacture.
The OmiCheck has the ability to read out the current injector codes and program in
new ones.
