First, traction control is a function of the Electronic Brake Control Module. You can't turn it off by using HP Tuners since nobody but GM and their supplier are able to do that. However, traction control depends on the engine to provide a requested torque level when the wheels start slipping. If the engine control module can't provide the requested level it sends a message to the EBCM telling it has an issue. The EBCM responds by setting a code (tells mechanics to look at the ECM) and turning on the traction control message and light.
First thing to do is to check to see which engine and abs codes are present. Usual suspects for this type of an issue are throttle control or misfire issues with the engine as they cause TC to shut off by interfering with the ECM's ability to provide the proper torque.

is not stock has headers gears C.A.I. 3200 stall non-stock tires and wheels no cats and O2 sensors have had car for 3 months has been running fine pressed traction control button showed traction control off pressed again showed service traction control reduced engine power check engine light took test drive engine power def. reduced I,m not very good with tuner and lap-top called previous owner he waled me through program on lap top disabled points which cleared all lights and restored full power he told me I would no longer have traction control he is very smart when it comes to tuning and programming I Believe I will have to go back into program and enable these points again which will then show all lights and then bring to dealer to be scanned just hoping someone might have an idear what problem is before I do this again car is running fine right now but I would like to get issue fixed also may show problem when I go for inspection sticker
