Trouble Diagnoses — Self-diagnosis Mode V

In real-time diagnosis, if any of the following items are judged to be faulty, a malfunction is indicated immediately. • Crank angle sensor (180° signal & 1° signal) • Ignition signal • Air flow meter output signal Consequently, this diagnosis is a very effective measure to diagnose whether the above systems cause the malfunction or not, during driving test. Compared with self-diagnosis, real-time diagnosis is very sensitive, and can detect malfunctioning conditions in a moment. Further, items regarded to be malfunctions in this diagnosis are not stored in E.C.U. memory.
