Abstract
A vehicle system is provided with an input pin, an interface unit and a microcontroller. The input pin connects to an external power source or ground through an external switch. The interface unit is adapted to connect to the input pin in a test configuration, and in a normal configuration for providing a wetting current to the external switch, and in a test configuration. The microcontroller is programed to: configure the interface unit in the normal configuration in response to input pin characteristics, reconfigure the interface unit in the test configuration, measure a test voltage of the interface unit, and generate output indicative of a status of the external switch based on a comparison of the test voltage to a reference voltage.
