MTS 1200 2016 - Connecting but can't reset or test
Posted: Sun Sep 07, 2025 1:54 pm
Hi all,
I have more or less connected my MTS 2016 to Melcodiag using a v1.4 OBDII USB reader with the PIC18F25K80chip - I can read a few parameters although they are funny like rpm reading when engine not running or the mileage which is not the real one
Nevertheless, I think my melcodiag license is recognised but I can not reset the oil service light, nor access the tests.
I am running windows 11 on a Surface tablet with only USB-C ports - I have to use an adapter - Could it possibly be a source of worries ?
I will post the debug file in the next message - Any help or suggestions are welcome
