Certains camions Silverado 2500HD\/3500HD et Sierra 2500HD\/3500HD des ann\u00e9es 2024 \u00e0 2026 peuvent pr\u00e9senter plusieurs probl\u00e8mes de communication et des erreurs sur le bus CAN, ainsi que l’allumage de plusieurs t\u00e9moins d’anomalie (MIL) et l’affichage de messages sur le centralisateur informatique de bord pendant que le v\u00e9hicule est en marche, en mouvement ou au ralenti. Le v\u00e9hicule peut \u00e9galement perdre la communication avec le module de commande \u00e9lectronique de freinage. Plusieurs codes d’anomalie (DTC) peuvent s’afficher, notamment le DTC B1980 (aucun identifiant d’environnement re\u00e7u du module de commande de circuit de freinage 1) et les codes d’anomalie de communication U1610, U0121, U2418, U2419, U160F, U0101, U0131, U1611 et U0401.<\/p>\n

Ces probl\u00e8mes peuvent \u00eatre dus \u00e0 une r\u00e9sistance \u00e9lev\u00e9e \u00e0 la masse sur les masses G103A et G103B du faisceau de c\u00e2bles de la carrosserie. Ces bornes sont situ\u00e9es sous le capot, du c\u00f4t\u00e9 int\u00e9rieur de la structure de carrosserie gauche des camions HD, \u00e0 c\u00f4t\u00e9 du bloc de jonction du faisceau de c\u00e2bles du moteur X50A (Fig. 16).<\/p>\n
