Quizplus · Accepted Answer

Technician A is correct because the Windows Graphical User Interface (GUI) is commonly used in PCs for truck data bus communication due to its widespread availability and compatibility with various software tools. Technician B is also correct because most Hand-Held Engine Service Tools (HH-ESTs) are limited in their ability to reprogram Electronic Control Units (ECUs) with proprietary data, as this often requires more advanced, manufacturer-specific tools or software.
