Retrieveing ECM Codes

Can somebody tell me what pins have to be shorted to retrieve the trouble codes from the ECM?

dude, you need a scanner. if your car is 1996 or newer you cont do it that way. i dont even think the older saturns will flash codes.

im against the idea of this, but you could just take your car to autozone to get the codes read

The easiest way to read the codes is to buy the cheapest ODB-II scanner you can find then buy a chilton or haynes manual for your car. They should list all the trouble codes for your car. I did it and spent only 70 bucks and I know I'll never get screwed.
