WABCO TOOLBOX 12.9 Diagnoctic

WABCO Toolbox 12.9 is the diagnostic software for older heavy-duty vehicles using the J1708 protocol. It reads and clears fault codes and diagnoses WABCO brake systems (ABS, EBS and more) on legacy trucks, trailers and buses — the version to use when your vehicles predate the newer CAN-based systems.
