Wife’s 2001 Limited 2wd, 253k mi. now, has had regular TRAC/VSC Engine lights on issue for past couple of years. Pretty much just cleared codes with code reader from time-to-time, but they always came back within a day or two. Just returned from an out of state trip for wife’s mother’s funeral, and some of the worst electrical problems all along the way. Had battery replaced under warranty, and replaced OEM alternator which finally died on the trip. After replacing recharged warranty battery following new alternator install, in Autozone parking lot no doubt with wife, 2 kids, dog, and cat in tow, all dash lights off and haven’t returned in 4 days now. Me thinks faulty alternator was somehow tripping the PCM to throw the TRAC/VSC Engine lights. Will report back if they come back on.
