Diagnosis & Testing


Diagnosis of base brake conditions that are mechanical in nature should be performed first. This includes brake noise, lack of power assist, parking brake, or vehicle vibration during normal braking.

The static and dynamic checks occur at ignition start up. During the dynamic check, the ABM briefly cycles the pump and solenoids to verify operation. An audible noise may be heard during this self-check.

If an ABS component exhibits a fault during initialization, the ABM illuminates the amber warning light and registers a fault code in the memory.
