      Has anyone done the 90c SAS "fix"?

      If so, is this https://www.matthewsvolvosite.com/fo...ic.php?t=58391 correct and does it really work?
      Thanks

      It sure does! Just solder the diode onto the ECM and say goodbye to the SAS DTC and the SAS system itself. I did it to my Dad's S70 about 4 years ago.

      Jim, that method described on that MVS link is correct and it does work. As for finding a Radio Shack that hasn't been boarded up and closed is another story!

      I kind of can't believe you've not done this before, given all the vehicles you've owned and the fragility/ expense of repairing SAS system.

      When I was dealing with the FEW 98s I bought and sold, I think I may have had to replace one (1) pump. This fix was not known but I found a good used one back then at a very good price.

      As for R/Shack, the one near me is open, but unless it's in stock, I'm SOL. They will not order any parts until the Chapter 11 is dealt with.
      I suppose that diode must be available somewhere.....

      Yes, I did it to my 98. Modifying the vehicle harness side with the diode is best in cases where you wish to swap ECUs.

      Ordered the diode.
      $7.00 for a 78c. part (shipping) *&^$(#$^&*(#
      All still existing Radio Shacks around here do not have any.

      I priced out a new air pump, haven't bought one in over 11 years.
      I almost fell out of my chair!!

      Now over $500 WHOLESALE for both parts and the gasket so I guess we will be doing the mod.

      Oh, does anyone remember the correct wire numbers? There seems to be a difference which number wire is the right one 32 or 33?
