abs, brake light and traction control light

01-07-2006, 12:30 PM
I Have A 2001 Lincoln Ls V8, Just Two Days Ago, My Abs, Parking Brake Light, And My Traction Control Light Turned On And Are Not Turning Off. I Am Beginning To Hear A Knocking Noise Coming From The Bottom Of The Car, Almost Like I Am Dragging Something, But I Am Not. Could Anybody Give Me Any Good Information Before I Take It In To Have It Checked Out. Thanks, Mike

I assume you've verified you don't still have the parking brake set, right? Did this happen after you used your parking brake? Possibly you have a sticking parking brake cable that is causing extreme drag on the rear wheels, so much that your ABS and traction control computers are detecting that all four wheels are not rotating at the same speed. You may want to get the rear wheels off the ground and see if they spin freely or if they drag.

Otherwise, I'd suspect you have a bad speed sensor ring or speed sensor at one or more of the wheels. I could understand that causing your ABS and Traction lights to illuminate, but don't know why that would cause the Brake light to come on.
