Analyse LSZ E46

Pour un projet a venir je vais faire une analyse du LSZ d’une E46.

C’est une analyse qui est en cours donc il peu y avoir des erreurs et des changements divers.

Pour commencer voici le schéma du LSZ non xénon typique avec les pins.

Ecriture des sorties

Il faut envoyer le résultat de la commande précédente avec les sources et destinations modifiées ainsi que la commande et évidemment les sorties a modifier.

Donc les sources, longueur et destination sont les suivantes:

3F 23 D0

La commande est celle-ci:

0C: Véhicule control
