An electronic control system for a vehicle having plural device actuators, each device being configured to provide an output signal indicative of its actuation status, the vehicle also having inputs for requesting actuation of the respective devices and generating corresponding actuation request signals, and vehicle condition sensors for providing vehicle condition signals indicative of vehicle parameters such as speed and tilt or the status of vehicle components; the system comprising: a slave controller associated with each device; and a master controller; the master and slave controllers all being connected to receive the vehicle condition signals, the master controller being connected to receive the actuation request signals and to receive the status output signals from all the devices and being in two-way data communication with all the slave controllers, and each slave controller being connected to receive a corresponding actuation request signal and to receive power from the master controller and to provide power to its respective device; each slave controller being responsive to an actuation request signal requesting actuation of its device to send a slave request signal to the master controller, and the master controller being responsive to the slave request signal provide a master consent signal to the slave controller only if it has independently received the same actuation request signal and it determines that it is safe and appropriate to do so, and to supply power to the slave controller; and the slave controller being responsive to the master consent signal and the relevant vehicle condition signals and the respective status output signal to supply power to the device to control the actuation of the device only in the event that it determines that it is safe and appropriate to do so.
