Abstract: A first speed sensor interface is operatively connected to a first time-space partition of a processor. A second speed sensor interface is operatively connected to a second time-space partition of the processor. A high side control is operatively connected to the first time-time space partition to receive a discrete command from the first time-space partition, and to receive a serial command from the first time-space partition. A low side control is operatively connected to the second time-time space partition to receive a discrete command from the second time-space partition, and to receive a serial command from the second time-space partition. The high side control and the low side control are configured to connect to an outside fuel shutoff device in manner that requires consensus between the high side control and the low side control to control the fuel shutoff device to shutoff fuel flow.
