The anti-lock brake system (ABS) light in an Acura TL is controlled by the ABS computer--a separate, standalone computer. The ABS computer actively monitors the ABS system to determine its functioning state. When the ABS computer senses a problem with the ABS system it stores a trouble code in its internal memory and illuminates the ABS warning light. An automotive scan tool is required to retrieve the trouble code from the ABS computer's memory and to turn off the ABS warning light.
