Mopar 05102525AA ABS Controller (also listed as 04879425AA) is an OEM anti-lock braking system control module designed to replace the factory ABS unit in compatible Mopar vehicles. It reads wheel-speed sensor data and uses it to regulate hydraulic brake pressure via the ABS modulator, helping prevent wheel lock during braking and preserve steering control. Identified by these two Mopar part numbers, this module serves as the vehicle’s ABS controller in applications that require the Mopar ABS control unit.
