Abstract: A state module selectively sets a present state to a first state in a predetermined order of states; a valve control module determines first target open and closed states for valves of a suspension system based on the present state and opens and closes the valves according to the first target open and closed states, respectively; a pump control module configured to, when the valves are in the first target open and closed states, respectively, selectively operate an electric pump of the suspension system in a first direction and pump hydraulic fluid toward the suspension system; and a diagnosis module configured to: record first and second values of pressures within the suspension system measured using pressure sensors, respectively, before and after the operation of the electric pump in the first direction, respectively; and selectively diagnose faults in a first subset of the valves based on whether pressure increases occurred.

Abstract: A continuously variable damper is disclosed. The damper includes an elongate outer tube and inner tube with a piston in the inner tube. The piston defines a rebound working chamber and compression working chamber. An active rebound valve is in fluid communication with the rebound working chamber through a rebound down tube, and an active compression valve is in fluid communication with the compression working chamber through a compression down tube. An intake compression valve is in fluid communication with the rebound working chamber through the rebound down tube, and an intake rebound valve is in fluid communication with the compression working chamber through the compression down tube. The opposite position of the intake valves balance the active rebound and compression valves to avoid asymmetric/bending loads on the inner tube in the damper.
