Multiecuscan

I try to connect to a Fiat Cinquecento engine code 1170A1046 but the system hang up.
I use interface OBDkey 1.4 with 3pin adapter. Pinout to 16pin female such in attachment picture.
I send also the log files and the foto of engine electronic unit IAW 6F.S0.

Please for help

Which year is Cinquecento?
Did you try to connect it with IAW scan?

Sometimes old ECUs are not supported.
For older Fiat and Alfa cars you need some other software.

Thank you for the post.
The manufacture year is 1994.
I have downloaded the application "IAW Scan 2" version v0.82.
Is there any newer version?

The 3pin adapter that I use is homemaded by me and I putted no resistance at all within.
Is the 3pin adapter correct?

Connection schematic for 3 pin connector is OK. No need to do any other modification

This ECU requires an ISO-KKL cable (also known as VAG-COM 409.1).

Damn... OBDKey supplies KKL and ELM.
