Aspects of the present invention relate to a control system (100, 200) for a vehicle suspension system of a vehicle (800). The control system is configured to perform a test for testing operation of an isolation switch (430). The vehicle suspension system comprises an actuator power supply (450) configured to supply power to the vehicle suspension system. The actuator power supply is configured to be electrically connected to the vehicle suspension system via the isolation switch. The control system is configured to: receive a shutdown indicator signal indicating that the vehicle is in a shutdown state (530); output an open isolation switch signal (524) configured to open the isolation switch in dependence on the shutdown indicator signal; receive an open isolation switch confirmation signal (516) indicative of the isolation switch being open; determine whether the open isolation switch confirmation signal is received within a predetermined time period; and output a test pass signal or a test failure signal in dependence on the determination.
