Abstract
An algorithm for detecting a fault in an ECM output signal by determining a status of the output signal, incrementing an error timer and a retry timer when the status is abnormal, incrementing a retry counter when the retry timer reaches a maximum retry time, and reporting an intermittent fault if the retry counter reaches a retry limit before the error timer reaches an error timer maximum.
