i have the 2lights on too- ABS/ TRACTION CONTROLL lights are on
both hubs are new, codes were cleared with OBDII computer , lights came on asap when car was started. these wire harnesses in rear ,are they easy to spot and change fix or repair??
These systems are related and it is typical that they both code when a failure occurs. Could be just a wheel speed sensor or something more significant like an ABS pump or controller. Re-check the codes and then diagnose the braking system.
I have replaced both front hubs, all sencors all work. abs traction control light on still.
Wheel speed sensor or ABS controller.
