    I'm coming up on my first oil change soon. What is the difference between resetting the Maintenance Monitor after an oil change and resetting the engine oil data on the ECU? I see two different procedures listed in my owner's manual, 9 pages apart - both indicate they need to be done. Does resetting the Maintenance Monitor accomplish both, or are these actually two separate procedures I need to do?

    Thanks.

    if i remember, two resets from the infotainment is all you need if you have the maintenance app.

    Havent changed 1st oil yet but I looked.
    So assuming all new cx5 now use this type.
    I believe Mazda changed drain plug to flange hex bolt type when they modified the SA-G 2.5L with cylinder deactivation in 2018 CX-5 MY.

    I also believe SA-G 2.5T on 2019 CX-5 keeps original Allen hex keyed drain plug as there's no change to the engine.

    There're 2 reset methods because there're 2 different types of instrument cluster. Your CX-5 GT has Type B cluster and you use Vehicle Status Monitor app in infotainment to reset 3 independent maintenance intervals. For oil change, you reset "Oil Change" tab only. The "Scheduled" tab listed on top has nothing to do with oil change. Make sure to choose Flexible OCI for Oil Change.

    BTW, you should have Flexible OCI from factory unless your dealer or you changed it. What is your current oil life left indicated in miles?

    I understand some Canadian CX-5 owners are having trouble to reset Oil Change maintenance monitor and I believe it's because Mazda doesn't allow Flexible OCI in Canada, and they screwed up the software programming when Mazda disabled the Flexible feature.

    Sorry if I wasn't clear. I understand the difference between the Type A and Type B Maintenance Monitors, and how to do the various resets on my GT's Type B Monitor.

    What I was really asking about is the separate set of instructions (located 9 pages after the MM reset instructions) titled "Vehicle Engine Control Unit Reset Procedure." There's no mention of Type A vs Type B monitors and it states that this procedure must be done after each oil change. However, the steps sound the same as the Type A MM reset, so I guess that I'm good with the Type B reset. It's a little confusing that this is listed separately and titled differently - it makes it sound like a separate procedure. Was just looking for confirmation/clarification.

    Thanks again.

    Did my first oil change today.Here are some pics.

    original japan filter vs thailand one that is currently sold by the dealers.





    the new oil plug for 2.5NA part no. if anybody is interested.
    I got a spare just in case.





    and this is going for oil analysis.
    I will post in the uoa thread once ready.
    Surprisingly the oil was very dirty for 3000 miles and 5 months.I guess local heat takes its toll. We'll see



    Oil filter and plug were very easy to unscrew.
    oil drain plug washer doesnt compress too much but seems good so far.

    The thailand oem filter is very nice because it has markings just how much to rotate/tighten.
