Try rotating the ignition switch slightly after you turn it to on and see if the lights come on...had the same problem and changed the switch fixed the problem...
SOURCE: 92 lexus ls 400 check engine and traction control light came on at the same time, 92 lexus ls 400.
the track off light will come everytime yhe check engine light comes on. this is normal. you need to have the check engine light checked first.you can go to your local parts house they will scan it for so you at least see what area you problem is in and then you can start from there. let me know lf you find out youe engine codes.

Simple fix... Just replace the brake light switch. It is located on the brake pedal arm about 6 inches above the pedal, it will have a plug going to it as well.

P0420 is "catalyst system below efficiency". It means that the car thinks a catalytic converter is bad. It could be that the cat is failing, but it also may be that the secondary oxygen sensor (behind the cat, used as a comparator to determine the health of the cat) is failing. As that part is about 10% of the cost of a new catalyst, I'd replace it first, have the code cleared, and see if it comes back.
