English to French Tech/Engineering Automotive / Cars & Trucks

"This service manual has been compiled in such a way that the manual may be used both in regions where the type certification is implemented based on the EU exhaust emission approval, and other regions. Hence, with regard to the *assignment*, reading, erasing of diagnostic trouble codes and those steps of checks, repairs and confirmation, the service manual contains the procedures for both cases."

Je sèche complètement sur la traduction de "assignment" dans cette phrase, je ne suis pas sûre d'en saisir le sens. Quelqu'un pourrait m'aider, svp ?

Merci d'avance !
