The solution for this case is indicated:

Hyundai Tucson 2017 1.7 diesel engine D4FD, TPMS system failure, in diagnosis: C1660 RF receiver circuit, error present and cannot be eliminated.

After testing all the sensors fitted in the tyres (direct type system) with a special instrument, and after consulting the circuit diagram (receiver integrated in body computer), an attempt was made to disconnect/reconnect the vehicle battery and the system started working normally again.

I hope it can be useful.

Greetings!
