hello,
i have a problem with a fiat ducato 2.3 EDC16C39 ECU. On the Dashboard didn't show the ecu light but the immo light. And if i connect diag software says "no communication".
I checked some pins (ground, 12+ and some can h / can l) all seeams good. Also bsi and ecu have connection on diag port (pin 7). I attached the flash and eeprom files. Maybe someone have an solution for that, because i saw some experts that repair this kind of problem.


thx for help :)
