You can reset the BMS light on a Ford Focus by turning on the instrument panel, inserting the ignition key into the appropriate slot: you will notice that the light will be indicated. To reset it, open the bonnet to find the components located inside the engine bay: the battery here must be disconnected by removing the negative terminal of the device.
