Re: Pulling Codes on 1989 Cadillac Fleetwood
Look under the dash for the ALDL, the 12 cavity diagnostics connector. Get a paperclip, and with the ignition on, jump pins A and B. They are the two pins at the top right of the connector. The Check engine light will begin to blink. it will first blink a code 12 by blinking once, short pause, then two successive blinks. There is a longer pause between codes. If you post the codes, I'll look them up for you.
