Hello:
I have just purchased a used '99 S80. I was driving about 30mph through town when my car told me that I had a brake failure and I needed to pull over ASAP. My brakes seemed fine, so i wasn't in immediate concern, but I pulled over at my convienence and turned the car off and back on again. Everything fine, all red lights are errors were gone.
I am concerned that possibly the alternator or regulator might be a problem. When I have the engine running and I look up at the interior light, I can see a slight unpatterned flicker very faintly. When I look at the battery voltage at the post under the hood to several different grounds, I'm seeing flucuations from like 13.65-13.85 volts constantly. To me that sounds reasonable, but I wonder if it maybe takes a large spike or sag at times when your driving, possibly causing a computer to trip or malfunction.
Has anybody any experience with a problem like this? It seems like this car has issues with ABS, STC module. It has 97,000 miles on it.
I hope that I didn't make a mistake trading in my Isuzu Trooper -- that was a very reliable vehicle for me...
Sincerely,
Deacon Eisenhart
