just bought my first Land Rover 2003 Discovery yesterday. yesterday no issues today when coming to a complete stop the traction control light, the abs light and the grade light all come on. If you turn off the ignition and restart the lights go off till the next stop.

 

Very common problem. Search for "three amigos", which are slang for the TC, ABS & HDC lights.

 

That is something you should deal with quickly, we call it the 3 Amigos and those parts of the ABS system are about to fail on you.
If you want, PM me your number and I'll walk you thru what to do and check.
