Abstract
An apparatus in a mechanical returnless fuel system is provided that includes a fuel pump motor for providing fuel to a powertrain system. A powertrain control module provides an activation signal for activating the fuel pump motor. A restraint control system includes a restraint control module for providing a disabling signal for disabling the fuel pump motor in response to a vehicle impact. An electronic relay switch is adapted for coupling to the fuel pump motor to selectably energize the fuel pump motor according to a conductive state and a non-conductive state of the electronic relay switch. A relay controller packaged with the electronic relay switch is responsive to the activation signal and the disabling signal for selecting the conductive state according to the activation signal when the disabling signal is not present and selecting the nonconductive state when the disabling signal is present.
