Eaton Corp.’s new MD-300 series diagnostics PC software quickly diagnoses heavy-duty commercial vehicle electronic systems through an SAE J1587 diagnostic link and a Windows-based graphical interface. A key benefit: it eliminates the need for technicians to know and manually enter the MID/PID codes by allowing them to select from a menu, thus saving time. The software can use any RP1210A compatible communication adapter; Eaton introduced its own adapter-the MD-100 series, along with the MD-200 series Vehicle Diagnostic Scanner-earlier this year.
