What does the ABC light mean?

When the ABC light in a car is on, it indicates that the Active Body Control system is in operation. Here is a related introduction to the ABC light: 1. ABC: ABC is the abbreviation for Active Body Control, an advanced active suspension system. 2. Body Stability System: The Body Stability Control System is an active safety system developed by Toyota, which significantly improves vehicle handling safety and driving convenience. 3. Precautions: In emergency situations such as sharp turns, sudden acceleration, or hard braking, the vehicle can quickly detect and take corresponding braking measures, such as individually controlling each tire while reducing engine output to maintain body stability.
The ABC light coming on generally indicates an issue with the anti-lock braking system, which prevents wheel lock-up during braking and helps maintain steering control on slippery surfaces. It may illuminate due to sensors blocked by mud or dust, loose wiring connections, or module malfunctions. I once experienced this while driving in the rain when the ABS light suddenly flashed, making the brakes feel unusually stiff. Fortunately, I was driving slowly and promptly pulled over. A quick inspection revealed dirty wheel speed sensors, and cleaning them resolved the issue. Remember, if the light comes on, stay calm, reduce speed, and pull over safely. Try disconnecting the battery for a few seconds and reconnecting it—sometimes this resets the system. If the light remains on, it's best to visit a professional repair shop to diagnose the trouble code with specialized equipment rather than attempting DIY fixes, as this could lead to safety risks.
The ABC light being on indicates an abnormality in the anti-lock braking system, which is crucial for driving safety, especially in harsh weather conditions. When the light is on, the vehicle may lose electronic stability assistance, and the braking distance could increase. I recommend slowing down immediately, parking safely, and conducting an inspection. Common causes include short circuits or open circuits due to aging wiring, low battery voltage triggering a warning, or possible water ingress and corrosion in the control unit. Last time I helped a friend with a similar issue, it took about ten minutes to check the fuses and battery connections, confirming it was due to voltage instability. To avoid bigger troubles, have a technician use diagnostic tools for an early check, and never ignore dashboard warnings in daily use. Safety first—don't wait for an emergency to discover the problem.
