I unplugged the battery and it didn't do anything. I'll check the brake fluid in the morning.

*EDIT* Yeah that didn't do anything, it was already topped off.

I'm going crazy with this also..First my TPS started going last thursday then today ABS and TRAC lights. I checked brake fluid, left the battery unplugged for 5 minutes, and still nothing. I'm picking up a TPS tomorrow and i hope that will help the problem. i'll keep everybody posted.

A new alternator huh? How did you figer that it was the alternator? my tracktion light have been on for 1 month now.

Ya these lights are still both on, UGH. Sometimes both lights will turn off and, trac/abs will start working perfect. X_X

I am currently having the same problem with my ES300, it first happened about 6-7 months ago, my ABS light stayed on while my trac off light was flashing. So i cleaned each wheel speed sensor, and I didnt see the light until recently about 2 days ago, the wheel sensors attract metal shavings that caused it to go off. Weird but Im assuming the cleaning of the speed sensors helped in my case. GL with ur soltuion, keep us updated.

lexySC_909: I just tested my alternator. A normal alternator voltage would be between 13 and 14 volts mine was 15, 16, and once and awhile hitting 17 volts.

Want one?

I turn off traction control as soon as I start up my SC300 and 9 times out of 10 when I take off quick out of a parking lot into the street (not tire squealing quick), the trac light will come on. Sometimes it will come on when I am up to full speed.

I can shut off the car and start it back up and the light will not show.
