Abstract
Methods and systems are provided for identifying degradation of a belt-driven integrated starter generator (BISG) active belt tensioner coupled to a vehicle engine. By using the monitored change in FEAD load to compare the actual state of the tensioner (either in retracted or extended state) relative to the commanded state, the presence of excess belt tension may be distinguished from the presence of insufficient belt tension. Timely diagnosis of a belt tensioner may be improve belt health and extend fuel economy benefits of a BISG system.
