Land Rover Repair: three lights on the dashboard, brake pads and rotors, wheel speed


Question
I have a 2002 Freelander and three lights appeared on the dashboard while I was driving and they have not gone away.  They are TC, ABS, and a third that I am not really sure what it is.  
I recently replaced my brake pads and rotors.  This was about two weeks prior to the lights appearing.  
If anyone can let me know what these lights mean, it would be greatly appreciated.  

Answer
It signs there is a serious problem with the ABS system, and  the ABS, Traction Control, and the Hill Descent Control was deactivated.

Oftenly either ABS wheel speed sensor's signal is wrong, or implausible.

You should go to the workshop to check the exact fault code.
