Obd1 scanner not reading any codes for check engine light, what am I to do?
what year chevrolet? OBDi (or 1) is a specific year range and OBDii (2) was mandatory in 1996. http://en.wikipedia.org/wiki/On-board_diagnostics#OBD-I
Some have key that will plug in and flash engine light as code indication. Need the year
1982 thru 1995 are OBD I. 1996 And newer are OBD II. HTH. -Jim
