If I understand correctly you are recommending that the instrument panel/body inline connector be inspected and any damaged terminals be replaced and this would be in your opinion fix vehicle issue.

This is the first thing to check. If it is inconclusive, you will need to diagnose each code. However, I think this bulletin will solve the problem.
