Section 2 – Getting Started Introduction ABS BrakeScan is the first tool designed for Do-It-Yourselfers to access the ABS diagnostic information. The Tool retrieves codes from the ABS system and provides the definition of each code to help pinpoint the problem areas within the Antilock Brake System that may have caused the ABS light to turn on. The Tool was developed by experts in the automotive service industry to access the information stored in the ABS module.
Getting Started both rear wheels. Under this system, if the left front, right front, or both rear wheels rotate at a speed different from each other, the ABS computer could use up to three separate solenoids to control brake fluid hydraulic pressure. This allowed the ABS system to control the left front, right front, and both rear wheels together independently. • Today, some vehicles have one wheel speed sensor per wheel for a total of four.
