What is an ABS Module?

Best Answer

All antilock brake systems control tire slip by monitoring the relative deceleration rates of the wheels during braking. If one wheel starts to slow at a faster rate than the others, or at a faster rate than that which is programmed into the antilock control module, it indicates the wheel is starting to slip and is in danger of breaking traction and locking up. The ABS system responds by momentarily reducing hydraulic pressure to the brake on the affected wheel or wheels. Electrically operated solenoid valves are used to hold, release and reapply hydraulic pressure to the brakes. This produces a pulsating effect, which can usually be felt in the brake pedal during hard braking. You may also hear a buzzing or chattering noise from the ABS hydraulic unit. The rapid modulation of brake pressure in the brake circuit reduces the braking load on the slipping wheel and allows it to regain traction, thus preventing lockup. It is the same as pumping the brakes, except that the ABS system does it automatically for each brake circuit, and at speeds that would be humanly impossible, up to dozens of times per second depending on the system (some are faster than others). Once the rate of deceleration for the affected wheel comes back in line with the others, normal braking function and pressure resume, and antilock reverts to a passive mode.

Audi 2000 a6. Abs light turned on and brake light is blinking how do you fix this?

take it to a garage take it to a garage more than likely its your ABS module. def. find someone to run a diagnostic on it first before you get a new module. Dont buy a new or reused module either. take you old module out and have it rebuilt. you can get the module rebuilt for 100-200 dollars. a used module will go out on you very soon and a new module will cost at least 1000 bucks. if its not the module, check your abs sensor and your brake sensors from your brake pads. i had the same problem and my abs module was dead and i also had a short in my wear sensor for my brakes.
