I had my 2017 gransport on the dyno today and the first run the brakes applied and now my abs traction control lights come on they go off when I turn the car off then back on but I drive about a mile and they come right on has anyone ever had this problem

 

If the car is under warranty go to the dealer and have the codes read. If the lights are coming on there is an ABS code of some sort causing them to light. An OBD II Scanner wouldn't be able to read them since it can only read power train codes but an OBD II Scanner with ABS capability could read them but if the car is still within the B2B warranty why bother.

lol it's not under warranty now I've done put headers x pipe cai and a tune

 

Your mods only invalidated the power train warranty. So it is still under warranty for an ABS issue if you haven't gone over 36K miles or 3 years from the In Service Date.

If your tune did something to screw up the ECM's response to torque reduction requests from the EBCM for Stability Control/Traction Control purposes then it wouldn't be covered. A good tune wouldn't attempt to do anything with those responses since they can be turned off with the push of a button.

However, you keep saying ABS and the ECM tune has nothing to do with ABS. ABS is contained completely in the EBCM, wheel speed sensors and the brake pressure modulator valve.

The least you can do is go to an Auto Parts Store that has an OBD II Scanner with ABS capability to see which codes are present. That will tell you right away where the problem area is located. If you see a code in the EBCM that says the problem is in the ECM then you know it isn't covered under the warranty.

The car is a system of subsystem that communicate and interact with each other in specific ways. You can't fix the problem by guessing you need to know the area/system the problem is located. The code is what gives you that information. Just remember when you see a code it doesn't tell you what to replace it tells you where to look for a problem and their are specific diagnostic procedures for each code to help narrow down the search to the correct part.

If you have messages saying you have an ABS/TC/Stability Control issue then you should look at items that are common to all three functions. One of those is wheel speed sensors. Maybe somebody knocked a wire loose when they were doing the dyno test.

Not trying to second guess you but maybe you should have purchased a Z06? You would have the added power and warranty.
