1. A system for filling a tank of a suspension system with hydraulic fluid, the system comprising:
a module configured to turn on an external pump and pump hydraulic fluid into the suspension system,
wherein the external pump is separate from the suspension system and is configured to pump hydraulic fluid into the suspension system via a port fluidly connected to a hydraulic line of the suspension system; and
a fill module configured to, after operating the external pump, operate a pump of the suspension system and pump hydraulic fluid from the hydraulic line into the tank of the suspension system thereby filling the tank.
