Il se peut que certains mod\u00e8les Silverado, Tahoe, Suburban, Sierra, Yukon et Escalade 2020-2021 pr\u00e9sentent des probl\u00e8mes de secousses pendant la conduite qui peuvent \u00eatre confondus avec un probl\u00e8me li\u00e9 \u00e0 la bo\u00eete de vitesses. Si ce probl\u00e8me concerne un v\u00e9hicule \u00e9quip\u00e9 du moteur V6 de 4,3 litres (EFC LV3), du moteur V8 de 5,3 litres (EFC L82, L84) ou du moteur V8 de 6,2 litres (EFC L87), il peut \u00eatre li\u00e9 au syst\u00e8me d’actionnement de l’arbre \u00e0 cames.<\/p>\n

Au cours du diagnostic, surveiller le param\u00e8tre de donn\u00e9es Variation de position de l’arbre \u00e0 cames dans le GDS 2 tout en reproduisant la condition de secousses. Bien que la variation cible soit de 0 (z\u00e9ro) degr\u00e9, il n’est pas rare d’observer une variation allant jusqu’\u00e0 3-4 degr\u00e9s sur un syst\u00e8me fonctionnant correctement. (Fig. 23, A) Toute variation d\u00e9passant 3-4 degr\u00e9s peut potentiellement causer une condition de secousses perceptible. (Fig. 23, B)<\/p>\n

S’il est d\u00e9termin\u00e9 que le probl\u00e8me est isol\u00e9 au syst\u00e8me de l’actionneur d’arbre \u00e0 cames, remplacer l’aimant de l’actionneur d’arbre \u00e0 cames et r\u00e9\u00e9valuer. Si les secousses sont toujours pr\u00e9sentes apr\u00e8s le remplacement de l’aimant de l’actionneur d’arbre \u00e0 cames et que la variation de l’actionneur d’arbre \u00e0 cames est sup\u00e9rieure \u00e0 4 degr\u00e9s, se reporter aux informations d’entretien appropri\u00e9es ou contacter le centre d’assistance technique pour obtenir une aide suppl\u00e9mentaire au diagnostic.<\/p>\n
