Abs, brake and traction control light stay on. how do i reset them

have scanned for trouble code --check and test brakes--abs sensors--connectors --wiring and hubs

First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

The light being on means the system has detected a problem in one or more sensors. The vibration is the ABS modulating the brakes to prevent skidding because it has detected a wheel that is locked up. That wheel is most likely the one sensor that is giving you the error.

I wonder if someone forgot to reconnect the connector from the sensor?

It is safe to drive. You need a scan tool to get a code out of it. Could be as simple as a wheel speed sensor going bad. All of these lights will work together normally. The traction control uses the ABS to gain traction, and the Brake Assist System is part of the stability control. Also uses the ABS.

ABS = Anti-lock Brake System.
TC = Traction Control System (Engine Control Module).
If the ABS lights on the dashboard permanently the ABS system is faulty. You must access the ABS & TC Electronic Control Units (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ABS ECU, in other words reset the ABS system and turn off the warning lamp on dashboard.
I suspect bad brake pedal switch, but you should scan the ABS & TC ECU's.

If brake pedal is chattering or pulsating it is most likely because you need either front or rear rotors, or both. They are rusted or out of round. If there is something wrong with either your abs or traction control,the abs or traction control light will come on & stay on. As soon as these lights come on, it automatically disables abs or traction control. If you would like to take out fuse that disables abs or traction control circuits, it will leave the lights on.You just wont have their functions. If by some strange condition your chattering goes away, then there is indeed something wrong with your abs or traction control.Fuses are labeled abs or traction either under hood or in your fuse panel in car.

Because the brakes were changed, either one of the sensors were broken when removing brakes or it has set a code. Go to your local autoparts store and have them reset the code. See if it comes back on. If it does you will need to look at the ABS sensors on each wheel and replace if damaged

you probably push air into the ABS unit when getting your lines replace but the Traction Control light might be on because the system might use the wheel speed sensor on the ABS unit to enable the Traction Control.......

Sounds like you have a problem in the front brakes or a front wheel speed sensor. A common cause for a Traction light is a faulty front ABS wheel speed sensor or harness. When the Anti lock brake computer sees a problem in the ABS syetm, it disables traction control as well.
