NO WARNING OF CHANGE IN STATUS MEANS THIS HAPPENS DURING TURNING MANEUVERS WITH POTENTIALLY DANGEROUS OR LETHAL CONSEQUENCES. CHECKING VARIOUS SOURCES NOTE THAT ABS MODULE FAILURE IS COMMON MAKING THE CAR POTENTIALLY UNSAFE IN EMERGENCY, NOT ONLY FOR BRAKING BUT DURING ACCELERATION AS THE CARS ABILITY TO PULL AT ITS NORMAL RATE IS VASTLY REDUCED, ADDING THROTTLE DOES NOTHING, BUT IF THE SYSTEM TURNS BACK ON AGAIN NO WARNING, THE SPEEDOMETER JUST COMES BACK TO LIFE ) THIS CAN CAUSE UNNEEDED FIERCE ACCELERATION. I NOTED ONE DEATH ON THE HIGHWAY OF A YOUNG WOMAN WHO APPEARED TO ACCELERATE OFF THE ROAD DURING A BENIGN MANEUVER AND AM CONCERNED THAT THIS ON/OFF SPEEDOMETER/ABS TRANSMISSION PROBLEM MIGHT HAVE BEEN THE CAUSE RATHER THAN THE ECM CURRENTLY THE FOCUS OF THE INVESTIGATION. *NM
