I have worked on cars before that trips the TRAC OFF light when the check engine light comes on. So it could just be one problem with the CEL code or codes. Have codes pulled and post the Code Numbers, not the description that some mechanics or part stores give for the code. Have them clear the codes after you retrieve them and it will probably reset the TRAC OFF light to.
There are places that pull these codes for free. Most auto parts store will retrieve them for you for free.
