In the event of a suspension air bag failure or rupture of the air line, there would be a loss of air pressure in the \"B\" system air reservoir that supplies air pressure for the front steer axle brakes.  This condition would increase stopping distance of the vehicle and under certain conditions could result in a crash.  Correction:  Dealers will install an air pressure protection valve in the \"B\" system air tank.","consequence":null,"remedy":null,"notes":null,"mfr_campaign":"A-0404","part_number":null,"units":10,"completion":null,"do_not_drive":null,"park_outside":null,"notification":"Safety Mfr","french":{"component":"Suspension","notification":"Sécurité - fabricant","summary":"Sur certains véhicules, la soupape de contrôle de la hauteur de la suspension à air pourrait ne pas être raccordée à une soupape de sûreté. En cas de défaillance d'un sac de suspension ou de rupture de la canalisation d'air, il se produirait une perte de pression d'air dans le réservoir d'air du circuit B qui fournit de l'air pressurisé aux freins de l'essieu directeur avant. Les distances de freinage seraient alors plus longues et, dans certaines circonstances, cette augmentation pourrait causer un accident.
