Slt! Je pense qu'il te faut le MUT 3 pour faire ce job. Comme je ne l'avais pas, un ami m'a passé un avdi pour refaire la resynchronisation etacs->ecu, c'est passé sans problème!
Maintenant j'avais lu un gars sur un autre forum faire ça à la mano! Je te met sa solution ainsi que des images illustrant le code de synchronisation dans les dumps; (
Merci à Furnata)

So after many try's i get the decision
All you need when you lost synchro between Etacs and ECU is to read (only eeprom is enough)9s12dg128 from etacs and 24c04 from ECU
Then open files with Hex workshop and see when is synchro lokated ( will post pics) in 9s12dg128
and write it in 24c04
In 9s12dg128 synchro is in 1a06 to 1a0c - 7 bytes
in 24c04 when the synchro is lost you'll get 77 77 77 77 77 77 77 41 in row's 170 and 180
so you'll need to write synchro from 9s12df128 in this two row's
You write this 7 bytes and the eith byte is checksumm (you need to calculate)
example:
synchro from 9s12dg128 - 6b ad 70 98 84 76 44
calculate cks. is 61
so you'll need to write in 24c04 6b ad 70 98 84 76 44 61
Then you'll nedd to calculate cks from all file and put in the very last 4 bytes in 24c04
That is without using MUT 3 and other equipment

Bonne chance.
ps: pour le chks, il précise l'avoir calculé avec hex workshop au cas où cela t'échapperai...
