Service Procedures

Replacing the Engine Oil

• Every time the engine oil is replaced, the parameter “Calculated oil dilution” in the PCM

must be reset with the aid of M-MDS (Mazda-Modular Diagnostic System). To perform

the procedure select the option ToolboxÆPowertrainÆData ResetÆEngine Oil and

follow the instructions of M-MDS.

Injection Amount Learning Function

• The injection amount learning function is used to compensate the deviations in the

injection amount due to mechanical wear of the injectors, achieving a smooth engine

operation. The injection amount correction function is carried out by the PCM under

specific conditions. In addition, the injection amount learning function has to be carried

out at specified service intervals by means of M-MDS. To perform the procedure select

the option ToolboxÆPowertrainÆEngine ChecksÆLearningÆInjection Amount

Correction and follow the instructions of M-MDS.

NOTE: The injection amount learning function is performed several times at a pressure of

35 MPa, 65 MPa, 100 MPa and 140 MPa. As a result, slight changes in engine

sound are normal.

NOTE: The injection amount learning function will be aborted, if the idle fluctuations of the

engine are too high (e.g. due to a faulty injector).
