A health status assessment method and system for a transport vehicle automatic or semi-automatic access device is disclosed. The health status assessment system has at least one leaf actuated by a kinematic chain including at least one motor having an associated angular position or rotation speed encoder and at least one switch. The health status assessment method includes steps for analyzing at least one actuating cycle of the kinematic chain between a first and a second position wherein, during one said cycle, information is acquired representative of the electrical energy consumed by the motor, or position or speed information provided by said encoder or binary information indicating positions of switches. The method further includes dividing said cycle into a plurality of functional segments based on said acquired information, calculating at least one descriptor value, and then establishing a health status diagnosis of the health status assessment system.
