A vehicle occupant restraining system includes a plurality of safety restraint devices and utilizes a main controller and a safing controller to determine whether or not conditions are proper for deploying each safety restraint device. The system discriminates between front, side, rear, and roll-over impact events and determines which safety restraint devices should be deployed in response to an impact event. The system also independently determines whether to activate a fuel cut-off switch in response to an impact event. The main and safing controllers utilize vehicle data from a main center tunnel sensor assembly and various satellite sensors to make deployment decisions. The safing controller is used to independently verify whether or not the safety restraint should be deployed.
