voicepro Posted July 23, 2014 Report Share Posted July 23, 2014 Well, drat! Few weeks ago my 98 DeVille starts giving me a dash display that says "Service Stability System." It's interconnected to the anti-lock braking and traction control, so those icons showed up even when I cancelled the SVS STAB SYS display. First thing I did was to have the tires rebalanced and rotated, even though it was a little early for rotation on this set of tires. Checked the brake pads while the tires were off, and all appears good in that regard. But that same code kept showing up intermittently. So today I went to my pal's garage and we pulled every wheel, and unplugged and replugged the sensors. Checked tire inflation while we had them off, too. Then I cleared all the codes and headed home...and after a few miles....there's that doggoned SVS STAB SYS display again. Really has me scratching my head....not a good thing, since I'm bald and I can draw blood when I'm really confused about something. Help me out here...if it's a faulty sensor, how the heck do you figure out which one? And does anyone know whether the sensors are part of the wheel assembly on a '98 DeVille or are bolt-ons? How can you tell...pull the wheel itself and not just the tires? Along with this I was getting an occasional Service Engine Light, but it doesn't appear regularly, so I discounted it as an anomaly. Oil still has three grand to go before a change is indicated, and I'm running top-quality synthetic. Giving some thought to a new set of plugs, but that has nothing to do with that pesky SVS STAB SYS indication. At the moment, I haven't a clue. Sigh.....
