Ecu full read and disable that DTC in sw, you cant exchange from one to cooper or vice versa because of fsc.

If you exchange cooper to one you have to flash one sw if possible and you will loose power.

If you exchange one to cooper you have to flash cooper sw if possible and inject fsc or you will have SWT tampering.

if not possible to flash you have to replace hw with correct type.

SWT works between cas vin, dme vin, fsc vin.

The other issue you can find in doing this is with power class, so if you want to solve this easily, suppress DTC swt tampering.
