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.
What causes the traction control to go offline?
The traction control computer in your vehicle is the “brain” that controls the entire system. A defect, corroded contacts or water damage in this computer can result in the entire system going offline, which will turn on the TCS warning light. As the TCS and ABS often share a computer, this may affect your ABS system and turn on that light, too.
