Technician A says that the secret of effectively repairing a break in the twisted wire pair used in a J1939 data bus is to use plenty of solder in the repair joint to minimize resistance. Technician B says that a damaged Hi bus J1939 twisted wire pair should be replaced, rather than repaired. Who is correct?
A) Technician A only
B) Technician B only
C) Both A and B
D) Neither A nor B

Question

Quizplus · Accepted Answer

Technician B is correct because the integrity and performance of a J1939 data bus system, which relies on precise electrical characteristics, can be significantly compromised by repairs, especially those involving solder which can alter the impedance of the twisted pair. It is generally recommended to replace damaged sections to maintain the network's reliability and performance.
