There are several possible factors that could trigger the ABS light to illuminate in a Toyota RAV4. This includes scenarios where the wheel speed sensors detect a skid or locked wheel, the speed sensor experiences a communication breakdown with the ABS module or malfunctions, and when the ABS module responsible for controlling the system malfunctions, resulting in the activation of the ABS light. The primary cause of module failure is often corrosion or damaged wiring. Additionally, a low brake fluid level can also activate the light. Inadequate fluid levels can lead to insufficient pressure in the lines, which in turn can hinder the proper functioning of the ABS system.

An illuminated ABS light is a common indicator that there is an issue with your brake system. This could be due to an abnormal reading from a wheel speed sensor or the ABS module itself. Typically, the only action an average person can take before seeking professional help is to check that the ABS fluid level is adequate.
