This paper introduces the application background of ABS on buses, the ABS components and their main technical data, the common faults of ABS and the diagnostic ways.

The system has the functions of diagram and digital displaying. It can reflect the performance of ABS clearly, and can quickly display the effect on ABS performance.

So, ABS Simulation Test Bed, which is a strong tool for developing ABS ECU, ABS HCU and so on, has the signification for shortening and studying time and saving the research funds.
