By | August 21, 2023


I tried to read a Merelli IAW 59F control unit of a fiat punto 1.28v but foxflash software gives an error. does id identification but does not read file. I tried with another one from an Opel corsa c1.2 and it gives the same error. Why the reading fail?

Double-check wiring.

Don’t connect bench box when tead IAW 59F ecu.

Or try to reduce voltage to 12.5 range.
