"Quantity correction (IMA) " And "stress correction (ISA) " are designed to adjust the amount of fuel injected by the Common Rail system into each cylinder within the permissible range. Seven-digit adaptation code -1- (The data in the figure is for illustrative purposes only) applied to each nozzle. Printed values may be letters and/or numbers (code-AScll).
When replacing an injector, it is necessary to write a value in the engine control unit for its adaptation. When replacing the engine control unit, it is necessary to write down "quantity correction values" And "voltage correction values (ISA) " into the new engine control unit. In addition, you should check that "quantity correction value (IMA) " And "voltage correction value (ISA) " entered correctly for all other injectors. If the correct correction values are stored in the engine control unit, they must not be re-entered. The adaptation process is described in Guided Fault Finding mode. Use Tester for this.
