ACDelco Releases New Version of OE Diagnostic Tool for GM Vehicles

June 22, 2016

ACDelco and General Motors Co. have released a new version of the Multiple Diagnostic Interface (MDI 2) for GM vehicles.

MDI 2 is a communications device that manages the transfer of data between a GM vehicle’s Electronic Control Unit (ECU) network and a personal computer.

ACDelco says the MDI 2 adds enhanced connectivity, plug-and-play setup, operation during engine cranking, extended temperature range, rugged design and many additional improvements. It also fully complies with the latest SAE J2534 and ISO-22900 standards.

“As automotive technology continues to advance more rapidly than ever, ACDelco service technicians have a new tool at their disposal with the introduction of the GM MDI
2 interface,” says Robert Sanford, general director, ACDelco.

“The next-generation interface allows them to diagnose and repair onboard automotive electronic systems in current GM vehicles, as well as future models.”

ACDelco says that although other manufacturers offer similar interface tools, MDI 2 is the only GM-supported tool that is fully functional for every 1996 and newer GM vehicle.

For a limited time, the MDI 2 (ACDelco part # EL-52100-AM) is available for a promotional price of $750.53. To learn more or order the MDI 2, call 1-800-GMTOOLS or visit
