Vehicle Engine Control Unit Reset Procedure (SKYACTIV-G 2.5T and SKYACTIV-D 2.2)
After replacing the engine oil, have a repair shop such as an expert repairer (we recommend an Authorised Mazda Repairer), perform the initialization (engine oil data resetting) of the recorded value. If the value recorded by the computer is not initialized, the wrench indicator light may not turn off or it may turn on earlier than normal.
The initialization (engine oil data resetting) of the recorded value can be performed using the instrument panel illumination knob in the instrument cluster as following:
-
Switch the ignition OFF.
-
Switch the ignition ON with the instrument panel illumination knob pressed and continue pressing the knob for about 5 seconds until the master warning light
flashes.
-
After the master warning light
flashes for several seconds, the initialization is completed.
