Abstract

L’invention porte principalement sur un procédé de diagnostic de fonctionnement d'un circuit (27) de gaz de carter de moteur thermique (10), dit circuit de blow-by, pour un véhicule automobile de type hybride par analyse d’une onde de pression (OP) émise pendant une phase de démarrage du moteur thermique (10), caractérisé en ce que ledit procédé comporte: - une étape de réalisation d'un diagnostic de fonctionnement du circuit de blow-by (27) lors d'un démarrage à haut régime du moteur thermique (10) effectué par une machine électrique tournante, - et dans le cas d’une suspicion d'un défaut détecté pendant la phase de démarrage à haut régime, ledit procédé comporte une étape de demande de démarrage à bas régime pour un prochain démarrage du moteur thermique (10), de façon à augmenter une durée d'analyse de l'onde de pression (OP) pour confirmer ou non le défaut du circuit de blow-by (27).
