dumb question... how do you actually get to read diagnostic codes? 700

The 700 FAQ mentions that you can read the diagnostic codes on 700 series volvos, but it doesn't tell you what you need to do it? On a toyota I used to have, all you had to do was short two particular terminals and a light would blink a certain number of times telling you the fault diagnosis...

... is there anything similar on the volvo? Do you need a scan reader or something?

88 740 GLE, 230F

    You don't. 88's don't have on board diagnostics.

      Actually, everybody in '89 had diagnostics except the turbos. I spent alot of time looking for that little black box on the driver's fender before I found that out.
