An engine starter interlock circuit includes an interface circuit configured to present a predefined load to a transmission controller for diagnostics and receives first and second transmission start enable signals. A first logic circuit is configured to output a control signal when the first and second transmission start enable signals indicate that the transmission is in a state where starting of the engine is permitted. A second logic circuit generates a start command signals when both the control signal and one or more vehicle start enable signals indicate that starting of the engine is permitted. A latch is configured to maintain the control signal in an asserted state while the start command signal is being generated (i.e., in the asserted state). The interlock circuit includes a switch responsive to the start command signal configured to energize an electric engine starter assembly for cranking the engine. |
