Question about 2007 GMC Sierra 1500
You don't need "reset computer" what you need is "diagnose and repair fault with systems monitored by the computer". Your ABS and traction lights coming on are most likely the same problem. Failed wheel speed sensors are a common cause of this, although several other things could be the problem. The airbag light will most likely not be related to the other lights at all (although it is possible that there is a circuit failure that is affecting all three). There could be a failure in any of the airbag circuits or seatbelt pre-tentioner circuits or any of the sensing circuits for this system.
NOTE: In the event of a collision, your airbag and seat belts WILL NOT FUNCTION PROPERLY if this light is on. The Supplemental Resraint Systems should only be serviced by a trained professional to ensure your safety.
To BEGIN diagnosis, the computer network in your vehicle needs to be scanned for fault codes, which will lead you to the correct diagnosis and repair procedure.

I suggest scanned the PCM and ABS modules to know exactly what fault code is stored there; generrally, when ABS and TRAC warning lights turn on, means some problem in the speed wheel sensors, but we will need what specific codes is there to send you additional details in order to solve it.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.

this warning light or any other stays on in the dash it is indicating
that the systems control module (or the system sensor in the case of
lights like low oil pressure, door open indicators etc.) has detected
a fault, it then disables the system (this applies to ABS,TCS, TCM,
SRS and BCM faults and others) as long as the light is on. You must
now have the dealer hook up a special electronic diagnostic tool and
"scan" the system for the fault code that is stored for the
Legend of Abbreviations. ABS Antilock brake system.TCS Traction control system, TCM Transmission control module, SRS Supplemental restraint system, BCM Body control module
