LAND ROVER DISCOVERY II ABS FAULT. I CANNOT DRIVE MORE THAN 5 MILES WITHOUT THE ABS, HILL DESCENT CONTROL, AND TRANSFER CASE WARNING LIGHTS ILLUMINATING. IT IS MY UNDERSTANDING THAT THIS FAULT IS A RESULT OF AN ABS SYSTEM FAILURE. AFTER FAULT HAS BEEN RECEIVED BY THE CARS COMPUTER, ABS IS NON-RESPONSIVE. THIS IS A SERIOUS SAFETY ISSUE AFFECTING MANY OF THE LAND ROVER DISCOVERY VEHICLES ON THE ROAD. I HAVE TAKEN THE CAR INTO MY MECHANIC WHO HAS BEEN UNABLE TO PINPOINT THE PROBLEM. APPARENTLY MORE THAN ONE ELEMENT TO THE ABS SYSTEM IS DEFECTIVE. THIS OCCURS EVERYDAY AND I'M STILL WORKING ON A RESOLUTION. I CANNOT SELL THE CAR IN GOOD CONSCIOUS WITH SUCH A HAZARDOUS PROBLEM. *TR
