Abstract

A fault detector (50) for a control system (1) that includes a controller (60), a solenoid driver (70), a current sensor (90) and a solenoid (80). The solenoid driver (70) provides a current to the solenoid (80) in response to a control signal provided by the controller (60) to the solenoid driver (70) and the current sensor (90) measures the current provided by the solenoid driver (70) to the solenoid (80) to determine a current measurement (40). At any moment, the control signal corresponds to one of a demanded zero current, a demanded first current magnitude or a demanded second current magnitude. The fault detector (50) detects a fault based upon a comparison of the current measurement (40) to an expected current range, wherein the expected current range is dependent upon which of the demanded zero current, demanded first current magnitude or the demanded second current magnitude the control system corresponds to at that moment.
