If the light is on at all times, even after several key cycles there is more than likely a fault related code stored in the EBCM (Electronic Brake Control Module). It would need scan tool diagnostics to determine what the code is, and a course of action.
Check the attached guide on check engine light scan, it is the same process for the Traction control system, which is usually tied to the ABS system. Also attached is a video on the subject that will may help
I also attached the wiring diagram for the ABS/Traction Control System
Check the guide/video and diagram and get back to us.
