Abstract

L'invention concerne un procédé de contrôle du fonctionnement d'une vanne de fermeture d'un circuit de carburant comportant une vanne basse pression, un régulateur de débit, la vanne de fermeture, caractérisé en ce qu'il comporte : - une étape de commande (30) de la fermeture des vannes ; - une étape de mesure (32) du débit de carburant dans le circuit qui est mise en oeuvre avant la fermeture complète de la vanne basse pression ; et - une étape de diagnostic (34) consistant à déterminer que ladite vanne de fermeture est défaillante lorsque le débit de carburant mesuré est non nul et à déterminer que ladite vanne de fermeture fonctionne correctement lorsque le débit de carburant mesuré est nul.
