 Vehicle Engine Control Unit Reset Procedure

After replacing the engine oil, it is recommended to have a repair shop such as an 

Authorized Mazda Dealer 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.

NOTE

There are two methods for resetting the engine control unit.

1.  The procedure described in the following.

2.  The procedure described in the maintenance monitor item when the flexible 

maintenance setting is selected. Refer to Maintenance Monitor on page 6-19.

If either one of the methods is performed, resetting of the engine control unit is completed.

NOTE

The initialization (engine oil data resetting) of the recorded value can be performed using 

the following procedure:

1.  Switch the ignition OFF.

2.  Switch the ignition ON with the dashboard illumination knob pressed, and press and 

hold the dashboard illumination knob for about 7 seconds.
