Abstract
An electric power steering system includes an electric motor configured to provide power to a steering mechanism of a vehicle. A controller operates the electric motor in response to an input. A flash memory device is in communication with the controller. A temperature sensor provides an output indicative of a temperature of a part of the electric power steering system. The controller is configured to power down or prevent power up of the flash memory device if the temperature of the electric power steering system is outside of a predetermined temperature range. A method of operating an electric power steering system includes measuring a temperature of the electric power assisted steering system and switching off a flash memory device of the electric power steering system if the temperature of the electric power steering system is outside of a predetermined temperature range.
