Cant reset/clear OBD codes on Gpec2 Dodge
Tried this with various Versions but I cant clear OBD codes, only reading is possible.
So I wonder if fuel reset is really working....

Try with key on, engine off. Also just connect the scanner, don’t be data logging when clearing codes or resetting fuel trims.

Tried it many times over diagnostic and behicle control.
Sometimes it works and sometimes not.
Confusing.
