Needing some help I have a 2012 tundra 5.7L 4x4 ROOCK WARRIOR. The issue I am having is the abs light and traction control light come on and stay on then the 4hi 4lo lights start flashing. I replaced a wheel speed sensor that read faulty but however it didn’t fix the problem. The truck runs good and drives good ,but these lights are driving me crazy. The truck will go into 4x4 as long as the lights aren’t flashing but if they are flashing the truck will not engage in 4x4. Any ideas or help be greatly appreciated.

Check the wiring from the wheel sensor to the ECU. There have been a number of problems with bad connections and broken wires.

Got it solved. It was a broken wire that was making the 4hi and 4lo flash and as far as the ABS and traction control replacing the the brake pump done the trick. Thank You for your advice
