Why is my anti lock brake light on?
The anti-lock brake system is a complex configuration of computers and sensors. When all of the components are working in perfect harmony, it ensures a quick, reactive system that can improve braking control under all surface conditions. Faults in this system are often first indicated by illuminated lights in the gauge cluster.
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.
Can a low tire pressure cause the ABS warning light?
The ABS and traction will detect that the rotational velocity on all tires do not match the expected. A low tire changes the effective radius of the tire, and therefore the rotational velocity will be different in the wheel with the low tire.
What does it mean when your TPMS warning light is on?
So check your tires carefully. If your vehicle has a TPMS, it’s probably monitoring the pressure in your spare tire. Therefore, if you get a low tire pressure warning light, and if you’ve checked all four tires that are touching the ground, than you might need to put some air in the spare.
When does the ABS warning light come on?
