Abstract:
A system includes a controller that executes a method for determining failure of the door latch sensor using both the door latch sensor and a door lock sensor. If the door latch sensor is faulty, the controller adjusts an automatic feature of the vehicle based on a door lock signal instead of a door state signal. The controller is also configured to mark the door latch signal as faulty if the door latch system is not functioning properly by using a fault counter that tracks the door lock sensor.
