The issue
Certain vehicles do not comply with the requirements of CMVSS 121. A standard fitting was installed in place of a single check valve on the park brake relay valve. A single point failure in the primary air circuits will cause the entire air system to bleed down without this check valve. Correction: Dealer will install a check valve in place of the standard fitting.
Description (français)
Certains véhicules ne satisfont pas aux exigences de la NSVAC 121. Un raccord standard a été installé à la place d'un clapet de non retour sur le robinet relais du frein de stationnement. Sans ce clapet de non retour, un seul problème dans les circuits d'air comprimé primaires provoquera la purge de tout le système d'air comprimé. Correction : Le concessionnaire devra installer un clapet de non retour à la place du raccord standard.
