1983 Cutlass Code Reader

(1990 Oldsmobile Cutlass Supreme)
in Lawton, OK on July 11, 2010
I have a 1983 Cutlass Supreme. The check engine light has come on and I can't find anyone that has a code reader to check it. Is there a reader somewhere I can buy on the market that can read this code? What code or protocall does this year use? All I see anywhere is OBD2 readers which doesn't work. Thanks for your help. Since that light came on my gas mileage has went down.

Jump terminals A and B on the diagnostic connector under the dash. Chilton's or Haynes manual they will outline the correct procedure and list the codes.

there is no code reader for obd 1 cars. you need a scan tool to determine the code.

There is a way to jump 2 terminals on the diagnostic connector. You will probably need to get a Chilton's or Haynes manual to find out which, and the check engine light will blink out the code.
