Where is file?
If 474 M5.2 = CC460, desolder, read.
If 467 M5.2.1 = 29F400, desolder, read.
Or, use inpa... for ews 2 and read isn in coding.
For EWS3... use Tool32

10 DE 00 00 00 00 00 00 00
but not working, something is wrong
but I do not know


if anyone helps me I will be grateful

Emulator must be the same to PDF, if You have other emulator PCB ... it not will working, only the original EWS2 emulator has the option of entering the ISN as it is in the ECU-> No need to convert.
Upload foto Your emulator for confirm.

oh sorry now its clear
i have JULIE universal emulator

[avital]

How it works I do not know. I one notice they do not know how to enter ISN into the emulator and they insert a constant bytes instead of a real ISN ... They do not know the full ISN algorithm for EWS2.
