Default Diagnostic Codes

I searched the forums for what each diagnostic code means but I came up short. I have a 90 and am shorting out the pins on the connector under the dash to display the codes on my dash. Im just curious if there is a site to show what each number code means.

It might cost you a few bucks but the money it will save you in the long run will be well worth it. You can get the code but to diagnose what the real problem is would be why you need the FSM. Their troubleshooting charts get right down to business and help you pinpoint the problem faster. Good luck!

What is a FSM? Is it like a code reader?

FSM means Factory Service Manual. I have a code book and plug in scanner that would work on your car for sale real cheap. The scanner doesn't do anything you can't do with a paperclip, the book is a good reference. PM me if interested.
