ACDelco GM Original Equipment Remanufactured Anti-Lock Brake System Control Module functions to control the vehicle's wheels helping to enhance braking ability on wet, slippery, or icy road surfaces. Remanufacturing ABS Control Modules is an automotive industry practice that involves disassembly of existing units, and replacing components that are most prone to wear with new components. Damaged and obsolete parts are replaced and are end of line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing returns components back into service rather than processing as scrap or simply disposing of them. These ABS control modules have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
