Abstract

L'invention porte principalement sur un procédé de récupération de défauts pour calculateur moteur (26), caractérisé en ce que chaque défaut pouvant prendre: - un état "détecté" lorsqu'un critère de fonctionnement n'est plus respecté, - un état éventuel "détecté avéré" lorsque le critère de fonctionnement n'est pas respecté pendant une durée de détection avérée de défaut, et - un état "confirmé" pris lorsque le critère de fonctionnement n'est pas respecté pendant une durée calibrable de confirmation de défaut supérieure à la durée de détection avérée de défaut, ledit procédé comporte: - une étape de génération d'informations (Inf def) relatives aux défauts détectés non confirmés avéré ou non selon les possibilités et la mise en œuvre choisie au cours d'au moins un cycle de fonctionnement du calculateur moteur (26), et - une étape d'enregistrement de ces informations (Inf def) dans une mémoire (27) du calculateur moteur (26) accessible par un outil de diagnostic.
