Verify your CHECK ENGINE indicator bulb is not burned out, it should light up when the car is started, and is located next to the TRAC light inside the speedometer. I had the same problem and couldnt figure it out, as there seemed to be no codes. But since the CHECK ENGINE indicator was out, I couldnt read the codes! www.lexls.com has a guide on reading the codes from your computer.

Had the same problem with my '92 LS400. Believe it or not, the fix came when I threw new brake pads in all around. The TRAC light shows up when the TRAC system can't build up the required pressure (mechanical or fluid problems I'm guessing?). Check your brake fluid reservour, is it full? Mine was low with old brakes, threw in new brakes, Bang! No more problem!

Also.. does the TRAC light show up AS SOON as you start the car? Or after you press the brake about 6-10 times, that could be another indication. I don't believe mine was ever on from the get go, but came on after driving just a little down the street.

Hope that helps!

My 92 had the "TRAC OFF" light and a "Check Engine " light, pulled a code 25 replaced both O2 sensors. All is well.

The traction control system in the '92 is not only totally USELESS it can easily and quickly get you into a hazardous situation.

I adopted the practice of manually turning it off just as soon as I started the car.

Just ignore the indicator or remove the bulb.

Or if you insist, do a brake fluid flush and that will often solve the problem. But be sure that whoever does the flush is aware of how to flush the TC assembly.

I can 100% agree. Highway speeds + passing + ice + TRAC = nasty 110km/h 360 degree spin going down the highway. I now manually shut the TRAC off as soon as I hop in my car! (but it was handy for low speed driving..)

The light shows up as soon as I start the engine. I changed the front brakes and rotors but not the back the front was severly worn. So maybe they need to be bled or I need to just change the back. Thanks guys for your suggestions and I'll keep you posted on the progress.

A descretly placed small piece of black electrical tape is the best solution overall.

I had trac light coming on intermittently, Lexus Dealer said it was sensor(?). Spent about $400.00 to have it fixed. That was a year ago. It is now doing the same again. I'm going to check the fuse, as recommended in another post, and get new brake pads. Also. turn off the tracking as soon as I get in the car.

interesting, zen... have you pulled the code?
i paid justask.com and a lexus tech there for an answer and he said they many times end up being the accumulator leaking. this is for code 19 troubles.
