Abstract
An exemplary embodiment relates to a method for detecting a failure on a differential bus. The method may include: determining an allowed voltage range of the differential bus based on a minimum load and a maximum load; comparing a differential bus voltage with the allowed voltage range; and determining a failure state in case the differential bus voltage is outside the allowed voltage range.
