A trailer control system for a trailer comprising: an electronic braking system (EBS); an electrical connection, by which electrical power may be provided to the trailer from an external source; and a fluid connection, through which pressurised fluid may be supplied to the trailer from an external source, the control system comprising a fluid sensor, positioned to sense the introduction of pressurised fluid into the fluid connection, and wherein, if the fluid sensor senses the supply of pressurised fluid into the fluid connection when no external power source is connected to the electrical connection, power is provided to the EBS from an on-board power source to activate the EBS. |
