Abstract

Procédé de contrôle du fonctionnement d'une installation électrique de chauffage (10) comportant au moins un élément PTC (13, 14), l'installation de chauffage (10) fonctionnant avec la tension de la batterie et recevant un courant. On saisit une valeur de mesure (24) représentant le courant traversant l'installation de chauffage, et on compare la valeur de mesure (24) du courant en tenant compte de la tension de la batterie, à au moins une valeur de référence (25, 26). En cas d'écart de la valeur de mesure par rapport à la valeur de référence, en tenant compte d'une largeur de tolérance prédéfinie, on conclut à un défaut.
