Can you drive without ABS module?
In the winter, braking on any slippery surface will be as if the vehicle isn't equipped with ABS at all: Locked wheels, no steering, and decreased control. But, the brakes still have all the functionality they were equipped with from the factory, just no electronic ability to help the driver in a bad situation.
Can you clean ABS sensors?

What does ABS tell you?
ABS sensors tell a computer (called a controller) when a wheel stops rotating while the car is in motion, which indicates that the brakes have locked up at that particular wheel. The controller then directs a hydraulic valve to release some brake fluid pressure to the wheel in order to let it rotate again.
Why does my ABS light on my dashboard?
If that controller gets insufficient data, or a hydraulic pump or valve isn't responding, it illuminates the ABS light on the dashboard. ABS relies on a properly operating conventional brake system. If the rest of your braking system is in working order, you should usually still have normal braking without ABS.
Why does my brake pedal make a grinding noise?
A low brake pedal or grinding noise could indicate that it’s time to replace your brake pads or rotors. Double-check that none of the brakes are frozen in one place, such that they drag all the time or won’t brake at all. A less jarring pulsating sensation under braking may be from warped rotors instead, especially if you haven’t replaced them for a while.

How do anti-lock brakes help you?
How do anti-lock brakes help you? ABS helps you keep control of your vehicle when you stop suddenly or brake on slick surfaces. By preventing the wheels from locking, you maintain traction and steering as you stop -- instead of skid. On some vehicles, anti-lock brakes may also decrease the braking distance required to stop safely, but this isn’t their main purpose.
Why does my brake pedal pulsate sometimes?
If your brake pedal pulsates during sudden stops or on slippery roads, that’s probably your ABS in action, pumping the brakes. Keep your foot on the brake until your vehicle stops.
