Check Engine Light came on. Very erratic. Very frustrating since no engine performance issue manifested. Codes referred to a possible ECM defect. Expensive repair. However dealer technician carefully investigated and diagnosed a broken wire in the harness. The repair required a soldered wire and rewrapping harness. Problem eliminated. I was actually impressed and pleased with the technician's work. It was expensive; but it required a lot of testing of wiring in the harness and in a way I was paying for the experience and knowledge of a good tech person
