"TRAC OFF" problems. HELP!!!

Hi, I was driving a 99 rx 300 4wd that I want to buy and the "TRAC OFF" light went on after driving it for a couple of minutes. When I shut the car off it goes away and then comes back on after a couple of miles. Has anyone had this problem, if so was it a huge issue or was it easily fixable?

Please help b/c I have to make my decision on wether to buy the car or not in the next couple of days.

Thanks in advance

It happened to my car once, and I asked my friend he said just dis connect the battery then connect it again then it will go off. It worked on my car and now it's fine andI don't think it's a big deal. But my suggestion is that you don't buy that car, or try to fix it and make sure it works fine first.

if its still under warranty, a lexus dealer can hook a computer up 2 it and clear the code.

strange never had that issue. dam lexus :-)
