What are the solutions for the illuminated ABS warning light in a Mercedes-Benz?

[LaMaya]

To address the illuminated ABS warning light in a Mercedes-Benz, a specialized diagnostic scanner is required to read the fault codes for targeted repairs. The ABS warning light may illuminate due to the following reasons: 1. Air in the ABS system lines: The presence of air in the ABS system lines can severely interfere with brake pressure regulation, causing the ABS system to malfunction. The ABS system functions by modulating hydraulic pressure to control the increase or decrease of braking force, and air can disrupt pressure transmission. 2. ABS control unit failure: The ABS system relies on the control unit for operation. If the control unit fails, the ABS will not function properly. Typically, ABS control unit failures are rare unless caused by abnormal voltage conditions. 3. Wheel speed sensor failure: The activation and deactivation of the ABS system depend on signals transmitted by the wheel speed sensors to the control unit. If a wheel speed sensor fails, the ABS system will inevitably malfunction.
