Consequence & remedy

IF THE DOORS CAN BE PUSHED OPEN WIDE ENOUGH,A PASSENGER MAY FALL OUT OF THE MOVING VEHICLE, CAUSING SERIOUS INJURIES.
Remedy: AN UNLOADER KIT WILL BE ADDED TO DUMP THE AIR OFF OF THE SMALL CYLINDER SIDE OF THE DOOR MOTOR TO INSURE THAT THE DOORS ARE POSITIVELY LOCKED AND CANNOT BE FORCED OPEN.
