Warning lights?

Can someone help? I have a 2003 Discovery SE, and I'm new at this...
I have 3 amber warning lights TC, HDC! and ABC up on the dash. What does this mean? And can I repair the problem myself? Never had any trouble before, Haven't been off road yet so what gives? There's 63K
on the rover if that helps? If anyone else has had this problem would
be greatful for some ideas.
Thanks,
rover girl
