I have a 2002 Land over Discovery Series II, my problem is the ABS, Traction Control and Hill Descent light in the dashboard is turn-on after i started my engine already. I want to this three (3) lights to be fix and removed but i don't know what to to first and which garage i should go to... The garage that they really knows what to do in my Discovery and at the reasonable price. Because some of the garage that i went already, they just cost me a lot of money but still my problem in the dashboard lights is Turn-on and not yet fixed.
