The BRAKE light on most vehicles is activated by…

Why is my abs and traction control light on?

Your car has sensors that monitor wheel speed and constantly relay information to the ABS and Traction Control system. When any of your tires have low tire pressure, the ECU ends up sensing an abnormal speed. It may send off inaccurate or flawed information to the ABS or Traction Control, which inadvertently activates their warning signals.

When does the ABS and traction control light come on?
