A potential fix
If you are incredibly lucky (I was) The following will fix your problem:
There is an accumulator next to the master cylinder ,should be some yellow tape on it cautioning about contents under high pressure, use a small piece of vacum hose on the bleeder nipple to avoid brake fluid squirting all over your engine compartment, with engine running bleed all the air from system , the trac light should go out.
The above solved my problem.
Below are a few other potential fixes.
Good luck!
There is a high pressure hose that runs beside the accumalator and it
gets soft and clogs up the unit.
When the TRAC light in the middle of the tach stays on it means the system is not functioning. Somewhere a component or sensor is making the light stay on. When I had this problem, it was because one of the electric control harnesses on the throttle body was loose. After I checked and reconnected the harnesses it worked great. Hope yours is as simple a fix too.
If your ABS system is not working, your TRAC will not work either.
There's a small vacum line to the right of the intake.tube. Check the line and check the little plastic fitting that the line goes on. I had to put epoxy on the fitting because it had a crack and was sucking air.
After I did this,no engine or traction light!
how many miles on your lex? if its got high miles it may just be o2 sensor.
My traction control was completely out and I had the TRAC light lit and I took it to the dealer.
They changed my o2 sensors and it fixed the problem
