I have a 2006 Mustang Gt. It was in an accedent. I had to remove the engine and replace the frame rails. When I put everything back together I am now getting an constant Brake light and ABs light. I first assumed that after I bleed the brakes they would go out, since I had to remove the front brake lines to replace the rails. But they did not go out. Do these lights come on and then need a scanner to turn them off or will they go off when the problem is corrected? I checked all the fuses and they are OK. Fluid level is good and I bleed the system.
