I was wondering if there is a test wire for code retrieval for my 1988 745t engine. There is test wires on the passenger side of engine for basic idle setting and another test wire for AMM / O2 sensor settings. I was wondering what the test wire on the driver side are for? Didn't know if this engine uses a flash (blinking light) codes. My car runs fine but, wondering if there is a faster way to diagnose any problems ?
