The Jaltest JDC303A is a specialized Adapter Cable developed for diagnosing ZF Ecomat transmission systems. This cable connects the specific 3-pin and 6-pin OBD connectors on the vehicle side to a standard 16-pin OBD2 connector on the diagnostic device side. The cable is designed for use in commercial and work vehicles, such as buses and trucks, equipped with this type of transmission.
