Default ABS, Traction Light on after changing part, no codes.

As the title said, I was driving a few months ago and after some light off roading on the way home the ABS and Traction light came on and the screen says Traction Failure, Service Stabil Sys and ABS Failure.

I have a BluDriver OBD-2 scanner and it scans ABS codes as well. The code that came up said that the Left Front wheel sensor was bad, so the other day I balanced and rotated my tires and swapped it out for a new one. After doing that the code went away in the scanner but the lights remain on as well as the 3 errors that cycle through the display.

I have cleared all codes and even did the turn key to on and press gas 3 times ABS reset trick and it makes 3 beeps but the lights never go off.

I am open to any ideas. I am confused why the lights would be on but there are no codes anymore after I fixed the one.

Welcome to HF.

Did you disconnect the battery?

KOEO pressing the gas pedal 3-5 times resets the OLMS (beeps to acknowledge), not ABS.

When you were off roading, did you encounter any deep water holes? If you get the T Case encoder motor/shift actuator good and wet, it can cause short and produce what you are describing less the wheel sensor. Get under, disconnect the T Case shift motor, inspect the wiring harness and connections, spray the connections with CRC Electronics Cleaner and snap back together after they dry.

Then start the truck and turn off the Traction Control, drive and see what you have. When you stop and shut it off it will default back to TC on, then see what you have.
