I've seen posts regarding the software from this site "http://www.obd-2.com", but unsure of it's features.

I've done all you suggest. Yes. I've trawled the web. All I've asked, over and over again, is "Are there software packages out there that will read all the fault codes from the OBD port of my '97 850? If I am to go to the dealer and pay him $200 for a readout, then I may as well give that much for a software package that I will still have for the next time. All I've asked here is which one will do the job for me? Is that too much to ask?

I posted a question a few days ago about why questions go unanswered.

One reason cited was that a lot of people do not answer questions posed by people "claiming to be", another was a dearth of readers during the summer. Having a profile can be handy - For instance I can look at information about Erwin and see that he posts quite a bit, he even posts information that he comes across without being asked. Some people might take a few extra moments to help him because of this.

Are you going to post your findings at some later date?

You might get more response by asking for some advice instead of asking a compound question.

What have you found by doing a search?

I view this site is more of a community than "Ask Jeeves" Just my 2 cents.

Yipeeeee. One in three of the replies are of some use. Now to further the question. Is this the only OBD II reader to give readouts of all codes, or are there others? And what about palm helds?? Are there softwares for these that will give a readout of all codes, and not just power plant/transmissions? I'm sure there must be. But which ones are they?? Let's see if we get a better response this time !! Let' see how helpfull those with the information really are at shareing it

This should all you ask:

And volvo-specific:

And yes.. It's expensive.

Bye, Arno.

what model year are you asking about? the OBD2 connector only reads motronic and TCM codes in cars with the DLC under the hood. '96 and up can all be read through the port in the console

I highly doubt that this question will be answered here because only those from independant shops are likely to desire such software IMHO. Those guys are likely to buy whatever is deemed best from their own research and might also depend on what's available at reasonable prices from tool distributors. It's likely that they'll buy software that'll work with cars other than Volvos too being that they'll need that for other types.
