I have a 1999 V70 with 165K miles. Periodically over the last year or so I would get an ABS light that will lite up temporarily and go out after a minute or so. I figured that this was a symptom of something that would happen in the future so I thought I'd wait it out. Recently on two occasions the following has happened the up arrow on the dashboard would flash and the transmission would appear to stay in third gear. Additionally this put him under needle would stay at zero and the odometer would read zero also. The total distance that I drove the car in the condition might be 200 yards. I read the in the archives and another Volvo website that the problem could be a failed ABS module which appears from all description to be something easy to replace with a new or rebuilt unit. I also read in the archives that the failure could be the PNP switch which I cycle back and forth as the archives mentioned.

I am fairly comfortable working on 240s but does the 70 is a different animal completely. Could I have one failure, that being the ABS module or the PNP switch? Could I have two problems ABS and PNP switch. I want to figure out as much as I can to keep the repair costs as low as possible the last thing I want to do is take a car to the dealer gets fixed in later find out that I could've done it myself.

Any thoughts would be appreciated. Thanks in advance.
