Here's what you should do:
1. Have the ABS system diagnosed: The ABS light is triggered by a variety of issues, including:
* Faulty wheel speed sensor: This is a common cause. The sensor monitors wheel rotation and feeds this data to the ABS module.
* Problems with the ABS module itself: This is more serious and often requires replacement.
* Low brake fluid: Check your brake fluid level – low fluid can trigger the ABS light.
* Faulty wiring or connectors: Corrosion or damage to the wiring can disrupt the system.
You need a professional-level OBD-II scanner that can read ABS codes. A basic code reader might not access the ABS system's diagnostic trouble codes (DTCs). An auto parts store often offers free code reading. They can tell you what the problem is.
2. Repair the identified fault: Once the problem is diagnosed, the necessary repairs must be made. This might involve replacing a wheel speed sensor, fixing wiring, bleeding the brakes, or replacing the ABS module (the most expensive option).
3. The ABS light will go out automatically: Once the fault is fixed, the ABS light should extinguish after a short drive, or after the system completes a self-test. If it does not go out after driving for a while, return to the mechanic to recheck the repair.
Important Note: Driving with a malfunctioning ABS system is risky. While your brakes will still work, you'll lose the anti-lock braking function, which can be crucial in emergency situations. Don't delay getting it checked and repaired.
