In engine control module clearing DTCs is supossed also to clear fuel trims (ECU internal behavior). Application does not allow issuing "clear DTC" command when there is no faults in the controller, thus not allowing to clear fuel trims.

I'm also interested in this topic. If the DTC clearing is not possible, is there a routine that clears this data/statistics?

That just views the readiness items, you need to be able to clear the codes to also clear fuel trims etc

That's right. So it would be great if I could send the clear DTC UDS job without an anctive fault.

^^ OK, I understand - not sure if OBD11 allows this under existing SW. Why not deliberately create a simple error via a coding change (on any module in the car), then reverse the tweak and clear the fault?
For example, tell the Central electrics module that the car is fitted with a burglar alarm by changing the adaptation channel Anti-theft device-Anti-theft alarm system to "installed".

This could be a solution, but it would be better if this could be done with a single button or e.g. with holding down the fault code refresh for a longer time.
(edit)
But as far as I can see, the requests from this forum are not handled well by the developer team.
