A low voltage electronic module interface, with a low voltage interface for an electronic module receiving a constant current from a body control module, the interface including a reverse current protection circuit 152; and a switch 154 operably connected in series with the reverse current protection circuit 152, the switch 154 being responsive to a status signal 144. The reverse current protection circuit 152 and the switch 154 form a low voltage electronic module interface circuit 150 having a resistance; and the resistance is selected so voltage across the low voltage electronic module interface circuit 150 is less than 2.70 Volts when the switch 154 is closed and the constant current 124 flows through the low voltage electronic module interface circuit 150.
