Hi! All
Using LABVIEW platform +NI-8502 (USB) to detect a vehicle domain controller, probably the process is to wake it up with specific instructions, then send diagnostic instructions, and then because of the need for security access, first send the request seed instruction, search the data containing seeds in the return data frame, after the seed is inverted bit, This is combined with specific instructions and sent to the domain controller.
Problem: Wake up and diagnostics resolved, not knowing how to search for the target data frame by frame ID and specific data bits in the data frame, and then extract the seed data in this frame.
