How to eliminate ABS?

Methods to eliminate ABS: 1. Go to a repair shop and use a computer to eliminate it; 2. Locate the car's battery, remove the negative terminal, wait a few minutes, and then reconnect it, and the ABS fault light will be eliminated. ABS is the Anti-lock Braking System, a vehicle safety control system with functions such as anti-skid and anti-lock. It can be divided into mechanical and electronic types, and modern vehicles are extensively equipped with anti-lock braking systems. ABS not only has the braking function of a conventional braking system but also prevents wheel lock-up, allowing the car to steer while braking, ensuring the stability of the car's braking direction, and preventing skidding and deviation.
A while ago, the ABS light in my car was constantly on, and I had a mechanic fix the issue. When the ABS warning light is on, don’t force the car to drive. First, check if the brake fluid is sufficient—the reservoir is on the right side of the engine bay. If the fluid level is normal, it’s likely that the wheel speed sensors are covered in mud or metal shavings. These sensors are the small metal heads with wires attached, located on the inner side of the tires. I cleaned the sensors on all four wheels myself using a toothbrush, and the warning light went off afterward. If cleaning doesn’t work, the sensor or the ABS control module might be faulty, and you’ll need to visit a professional shop to read the fault codes with a diagnostic tool. It’s best to drive slowly through puddles or muddy roads, as water getting into the sensors can easily trigger the warning light.
Don't rush to repair when the ABS light comes on. Here's a money-saving tip: First, park the car safely and turn off the engine, then disconnect the negative battery terminal for 5 minutes before reconnecting. This can reset the system and resolve false alarms caused by system errors. If the light remains on, focus on checking the wheel speed sensors on the inner side of the tires—these components are particularly sensitive and can malfunction with just a slight bump or a bit of dust. Last time, my car had a loose connection on the front right wheel sensor, and simply plugging it back in fixed the issue. If the ABS light flashes while driving and is accompanied by a pulsating brake pedal, pull over immediately to check the brake fluid. In such cases, it's likely due to a leaking brake line or a problem with the pump.
Don't panic when the ABS warning light comes on—it's usually caused by one of three things: wheel speed sensor, control module, or wiring issues. Sensor problems are the most common, with each wheel's sensor in a different location: the left front behind the steering knuckle, the right front near the suspension joint, and the rear wheels hidden inside the brake discs. I've personally tested the signal wire voltage with a multimeter—it should read 12V normally. Use WD-40 to clean the sensors, as brake cleaners can corrode the coating. If the brake pedal becomes stiff and pulsates, seek immediate repairs—this indicates the ABS is activating protectively. Modified brake systems require extra attention, as overly rigid brake lines can falsely trigger the warning light.
