Vehicle Engine Control Unit Reset Procedure
The following procedure is for SKYACTIV-D 1.5 and SKYACTIV-D 1.8 vehicles, and for SKYACTIV-G 2.0 vehicles with the engine oil flexible maintenance setting selected.
After replacing the engine oil, have a repair shop such as 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 following procedure:
-
Switch the ignition OFF.
-
Switch the ignition ON with the selector pressed, and press and hold the selector for about 5 seconds until the master warning light
flashes.
-
After the master warning light
flashes for several seconds, the initialization is completed.
