Abstract
A door check system of a vehicle includes a door check assembly having a check body securable to a door of the vehicle, a check link extending through a check body opening of the check body and an adjustment mechanism positioned at a body of the vehicle. The adjustment mechanism includes a housing defining a housing opening, and an adjustment slide positioned in the housing opening and slidable moveable therein. The adjustment slide is secured to the check link. An adjustment feature is secured to the adjustment slide and extends through an adjustment slot in the housing. Moving the adjustment feature along the adjustment slot moves the adjustment slide in the housing opening to change an effective length of the check link.
