Electrical circuit diagnosing method for operating actuators of internal-combustion engine, involves examining electrical circuit for identifying electrical errors in consideration with information of misfire recognition

摘要

The method involves examining an electrical circuit (45) for identifying electrical errors in consideration with information of a misfire recognition (600), where a recording unit (420) detects the information of a misfire recognition. The electrical error is considered as relevant errors, when the electrical error is registered several times. A monitoring unit (410) verifies the electrical circuit for operability. Independent claims are also included for the following: (1) a diagnostic device for diagnosing an electrical circuit (2) a computer program product with program code for performing a method of diagnosing an electrical circuit.
