When the ABS system detects a problem a fault code is stored in the ABS system control unit. When an error occurs the ABS warning light located on the dashboard flashes or stays on steadily. The ABS computer stores a diagnostic code until the malfunction has been repaired. To retrieve ABS trouble codes on older vehicles can be tricky because of the variation of retrieval methods; in this case a car repair manual is needed. On newer vehicles a diagnostic information connector is located under the dash on the driver's side; a trouble code scanner can be attached to retrieve ABS codes similar to engine trouble codes. After the problem has been repaired codes should erase automatically with no procedure from the scan tool. (Real time system) after the vehicle has been moved about 6 feet and the brake pedal has been pressed for five seconds. When repairs have been completed the ABS, MIL (malfunction indicator lamp) should not be illuminated, if the ABS light remains on there is still a problem, re-scan the ABS computer for further repairs.
ABS brake systems apply more wear and tear to the brake fluid and can wear brake fluid down chemically. Be sure to flush your brake system with manufacturer recommended brake fluid (DOT 3 or 4) when brake service is performed to ensure proper operation of the ABS brake system in your car
