How do I clear countdown mileage message after repair

[smokeymo]

Hi all,
I recently had a code come up ro replace the Reductant heater line.
i changed that and cleared the engine code but I am u able to clear the stored message mileage countdown.
Do I need a high end scanner tool to do that?

You’ll need an elm327 adapter from Amazon and download alfaobd on a windows laptop or android phone
