According to you, where am I wrong? Iaw 5af

[luchetto19]

Good evening all, I have tried to scodificare a iaw 5af, that small as the 59f to understand.l I put it in the boot read with the galletto processed with immo Universal devoding and in the process of writing appeared to me to be a message that would not correct the checksum, I have given ok equally pensado who had already fixed the software, at the end of the writing I wanted to try the ecu on my 600 that mounts, however, a 59f and when I go to turn the ignition you hear a strange noise in the relay and the machine will not do you think it is a problem of the checksum or is it a problem of the ecu given that it is two ecu's different?

hello on the fiat 600 nn you can try 5af is not compatible

The 5AF is mounted on the machine with the body computer, so no communication can given that the 600 has no body. Instead of the 59F have it mounted on the car without the body. You need a 59F the same type and with the HW the same, because then they could change it to ****llo of components.

Ok...so the checksum is correct according to you ?

I need your help because I still have problems with this ecu...let's see, I read the file ori l I tried with immo universal decoting then not sure of the cecksum I went on the ecm, I loaded the file ori and mod file, I open the checksum feature, the selected family of the ecu and told me that the checksum was wrong, I correct and the file is saved and written on the ecu...I mounted the ecu on a lancia y with the pump, but the car no... what's happening?

If any moderator passes by here, wonder if you can move the discussion on immo off perhaps to get perhaps the visibility that is most appropriate
