Question

Quizplus · Accepted Answer

Technician A is correct because post-2014 trucks use the green 9-pin Deutsch connector for the J1939 data bus, which is the standard for newer vehicles. The green connector signifies compliance with the newer, faster CAN standards. Technician B's statement is incorrect because it contains a typographical error with the year "2104" instead of "2014", and also, the black 9-pin connector can still connect but is associated with older protocols and might not support all functionalities of newer systems.
