Why would ABS kick in for no reason?

Why would ABS kick in for no reason?

A weak signal from a sensor is interpreted as a locked wheel, which triggers the computer to activate the ABS system and release brake pressure in an attempt to unlock the wheel. Instead of activating the ABS module and causing long stops, the system will deactivate and the ABS warning light will turn on.

Can low brake pads cause ABS light to come on?

Most commonly, this light is triggered by low brake fluid or an engaged parking brake. However on some vehicles, it can simply indicate a problem elsewhere in the system and can be illuminated immediately if there is an ABS fault.
