Two bad ecu pinout:
Iveco EDC17C69 (0281032557) factory mode.
PIN21 - GND (If not connected, it will not work)
PIN20 - clock 2 signál 10uF connected

Mercedes Benz EDC17C43 (0281017238) factory mode.
Clock2 signál PIN 94 no good. Clock2 signál connected PIN 39.
PIN59, PIN70 - GND not necessary

thank you very much for the feedback we will look into it and if need correction will do it.

hello
we have checked it and find out our wiring is wrong for EDC17C43 we will correct it soon, but when coming to edc17c69 we already have wiring with capacitor but are you sure the ground on pin 21 i s mandatory?

ok sir we will add wiring on that ECU pins. thank you for notification.

I found on VAG Simos 18.1 , 18.2 ( I think all Simos 18 ) also problem in Boot mode. I it will communicate with ECU but when it goes to Unlocking , after 1-2 min I get message " ECU rejects to enter session"
The problem is Signal (CFN) wire, On your diagram it has only 1 Signal wire , but it needs to be in 2 places , Everything else is good . After I connect signal wire on those 2 places , it read ECU with out problem.


Here is the picture with correct pin out for Signal wire.

Here is the picture with correct pin out for Signal wire.

really appreciate the feedback, some ecu worked without that 2 CNF that's why we did not add it so we will correct the wiring diagram soon and add one more CNF.
Thank you very much

You are correct, Had other ECU and needed only 1 CNF,one that originally is on diagram.
Probably will be best just to add One more picture with 2 CNF and put like Version 2 .
