How to test ABS system in vehicle?

Please note, that ABS system cannot be tested manually.When the problem occurs in ABS system, the ABS light will get steady on your car/truck/jeep dash.In that cases the error gets stored in your cars ABS module.It has to be scanned by professional scan tool.Then only you will receive error code.Once the error core is retrieved, you can easily located the fault.

The ABM monitors the systems input and output circuits to verify the system is operating correctly. If the on board diagnostic system senses that a circuit is malfunctioning the system will set a trouble code in its memory.
