Check bearing and joint/knuckle on every wheel and even on the drive shafts, if there is lack/knocking, that could cause abs and esp light,because sensor doesnt give right information and ecu only records sensor fault butdoesnt say why the infromation is wrong. They changed the sensor but didnt solve the cause!!!
the problem I have found with fords is that the stator ring that is on the cv shafts(drive Shafts) crack and will dislodge. this will cause an abs / traction control code. these can be spot welded back on to hold. Just push them back in place and don't worry abour the gap
Hi, Sounds like your abs braking system is at fault.
The light would normally flicker when traction (tyres loosing grip with the road) is lost, Then as regained the light should go back out, however you have a sensor on each wheel either one of those may have packed in or your main ABS control unit under the bonnet may be at fault or on the way out. Also it may be your traction control switch that could be at fault.
Hope this helps.
It's probably your brake check switch going bad, it's under the driver's side dash above the brake pedal. I had the same problem and eventually my cruise control and brake lights stopped working when it failed completely. This is also a redesigned part that you can get from the dealer for about $8, which to me indicates they new the part caused problems and failed to notify owners. Try that before Audit tries telling you wires are faulty.
