A seatbelt latch circuit can include an illumination source configured to illuminate a seatbelt latch in response to a signal. The seatbelt latch circuit can also include a status sensor configured to output a first current if the seatbelt latch is in a removed state, output a second current if the seatbelt latch is in an inserted state and output a third current if the seatbelt latch has a fault. The seatbelt latch circuit communicates with a vehicle electrical system through only two conductors.
