Abstract

L'invention porte sur un procédé de diagnostic d'une charge électrique (6) d'un véhicule automobile (100), caractérisé en ce qu'un deuxième câblage (1) est branché d'une part à la charge électrique (6) et d'autre part à une unité de commande (9), le procédé de diagnostic comprenant les étapes suivantes : (E10) - mesure d'une valeur de tension (+Vcharge) à une borne positive de la charge électrique (6) par l'intermédiaire du deuxième câblage (1), puis (E20) - comparaison de la valeur de tension (+Vcharge) à la borne positive de la charge électrique (6) à au moins une valeur seuil de tension (VL, VN), puis (E50) - indication d'un fonctionnement normal ou d'un type de défaut en fonction du résultat de l'étape (E20) de comparaison de la valeur de tension (+Vcharge) à la borne positive de la charge électrique (6).
