Que signifie votre code Code Défaut BMW ?
Grace au système OBD, les
Bmw
fabriqués après 1996 sont normalement équipés d'une prise diagnostique OBD.
Si l'ordinateur de la voiture rencontre un problème,un code d'erreur ou un code de diagnostic (DTC)
sera stocké dans la mémoire de l'ECU de la voiture.
Avec un lecteur OBD branché sur le port OBD (On-Board Diagnostics) de la voiture, vous pouvez lire la liste des codes stockés, et donc découvrir quel est le problème.
Les codes suivent une formule permettant de savoir généralement quel est le problème avant même de regarder le tableau ci-dessous.
Nous vous présentons ci-dessus une liste très complète des différents codes défauts possibles.
Si le code défaut de votre auto s'affiche au tableau de bord, vous n'aurez peut-être même pas besoin d'un lecteur OBD . il sera dans la liste .
Réparer le code défaut de votre auto, c'est potentiellement simple à faire avec vos revues et méthodes techniques.
