Land Rover Repair: Warning lights, land rover discovery, shuttle valve

Question
I have a 2002 land rover discovery se,and my brake lights,tc&abs lights are on.

Answer
The most common faults that bring on these lights are faulty wheel speed sensor(s) and failure of the shuttle valve in the ABS modulator.  There is no way to tell why your lights are on, however, without reading the codes with a factory compatible scanner.
