My 2001. 5 Emergency brake was the cause of my light staying on. The only to get the light to shut off, was to press the pedal to the floor and release it fast and it would slam into stop. Then the light would go out. On the drivers side just behind the door on the outside of the frame you can make an adjustment to tighten up the e-brake cable.
