Speedo kmh to mph

Hi All

I have 3 Toyota imports and iv switched speedo on all 3. From kmh to mph . Yaris And corolla, 2022.

They all work fine but I'm left with tpms/two light flashing on start up and they staying lit.

Could anyone help with what I need to do, I still have all the old speedos.

Thanks 

Hi Yassar,have you checked your tyre pressures to see if this is triggering the TPMS lights, if all pressures are OK reset the TPMS and drive the cars for a while to see if this clears. If this fails then reinstall the old speedo and see if the lights then go out this will confirm if the systems are linked but in my understanding they are two separate systems, but It's possible they are integrated but at least this should confirm where the problem is.Hope this helps.
