Where is the abs brake controller?

An anti-lock braking system, or ABS (from the German, Antiblockiersystem) is a safety system which prevents the wheels on a motor vehicle from locking while braking.

A rotating road wheel allows the driver to maintain steering control under heavy braking by preventing a skid and allowing the wheel to continue interacting tractively
with the road surface as directed by driver steering inputs. While ABS
offers improved vehicle control in some circumstances, it can also
present disadvantages including increased braking distance on slippery
surfaces such as ice, packed snow, gravel, steel plates and bridges, or
anything other than dry pavement. ABS has also been demonstrated to
create a false sense of security in drivers, who may drive more
aggressively as a result.[citation needed]

Since initial widespread use in production cars, anti-lock braking
systems have evolved considerably. Recent versions not only prevent
wheel lock under braking, but also electronically control the
front-to-rear brake bias. This function, depending on its specific
capabilities and implementation, is known as electronic brakeforce distribution (EBD), traction control system (TCS or ASR), emergency brake assist (BA, EBA or HBA), or electronic stability control (ESP, ESC or DSC).
