How do I reset the trac light off/on switch on 1997 Lexus ES300

The trac light stays on all the time while the care is running,pushing the button below the dash does not turn it off. but when it is not running and the key is on ACC the switch under the dash will turn it on and off. I do need a O2 switch that code showed up the other day, we ran looking for a code on the trac switch but there was no code... is there a reset in the engine compartment

scan codes and post so we can adv. your yaw sensor may need to be relearned
