When the ABS light comes on in the car, it indicates a fault in the ABS system. The reasons for the ABS light illuminating are: 1. Faulty wheel speed sensor; 2. ABS wiring fault; 3. Faulty ABS pump or pressure regulating solenoid valve; 4. Fault in the ABS computer. The inspection methods to take when the ABS light comes on are: 1. Check if the parking brake is fully released; 2. Check if the brake fluid level is within the specified range; 3. Inspect the ABS electronic control unit's wiring plugs and sockets for proper connection; 4. Check the wiring connectors and wires for proper connection or contact; 5. Ensure all relays and fuses are intact and securely plugged in.
