In 1989, the Mazda MPV was introduced. For earlier versions of the MPV prior to the implementation of OBD II in 1996, the procedure to reset the check engine light is different with later versions of the vehicle. Many auto parts stores or repair stations will even scan or reset your codes for free as long as the proper repairs have been made to fix the problem. Resetting the check engine light in the Mazda MPV should only be performed after the DTC has been properly diagnosed and the repair has been made to resolve the problem that triggered the DTC.

1. Open the hood to the Mazda MPV and disconnect the negative terminal clamp from the battery. Loosen the retaining bolt with a hand wrench until you can wiggle the clamp off of the battery post.
2 .Go to the driver's seat and insert the keys in the ignition.
3 .Turn the ignition to the accessory power position (two clicks forward) and then turn on the headlight switch. This will purge any stored reserve power from the battery connection to the power train control module.
4 .Turn the headlight switch off and then turn the ignition key to the off position and remove the keys.
5. Wait 10 minutes and reconnect the negative battery terminal clamp. Tighten the clamp's retaining bolt with the hand wrench until the clamp is secure against the battery post.
6. Start the engine and check the instrument panel to ensure the check engine light is out.
7. Locate the data link connector (DLC) outlet beneath the steering column on the MPV. On later versions of the MPV, the DLC is slightly to the left of the steering column.
8. Plug the OBD II pocket scanner into the DLC.
9. Turn the ignition key to the accessory power position (two clicks forward) and then follow the onscreen menu of the scanner. There are some scanners that feature an "erase" button. On scanners with an "erase" button, simply press the button. Other scanners will require scrolling through the menu to choose the erase code or erase DTC (diagnostic trouble codes) option.
10. Press the "send," "erase" or "enter" button to reset the power train control module. Wait for the scanner to instruct you that the command has been sent or the main menu reappears.
11. Turn the engine on to ensure the check engine light is no longer illuminated on the instrument panel.

In a word, if the triggered DTC is a hard code, the check engine light will re-illuminate almost immediately. Resetting the check engine light will not allow the MPV to sneak through state inspections that require emissions testing.
