Technician A says that MB-4000 engine controllers are designed to broadcast data on a J1939 data bus. Technician B says that because MB-900 engines are built offshore the data bus will not display the SAs, MIDs, PGNs, PIDs, SIDs and FMIs that enable generic readers to access the electronics. Who is correct?

Question

Quizplus · Accepted Answer

Technician A is correct because the MB-4000 engine controllers broadcasting data on a J1939 data bus is a standard practice for many modern engines, allowing for standardized communication across different devices and systems. Technician B's statement is incorrect because the origin of manufacture (offshore or not) does not determine whether a data bus will display standard diagnostic codes like SAs, MIDs, PGNs, PIDs, SIDs, and FMIs. These standards are designed to be universal to enable generic readers to access the electronics regardless of where the engine is built.
