An ACDelco GM Original Equipment Remanufactured Vehicle Control Module is a GM-recommended replacement for your vehicle's original component. It regulates various parts of your vehicle's engine. Remanufacturing the vehicle control module is an industry standard 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. This vehicle control module has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
