Armed with a oscilloscope and multimeter are their specific measurements i can make to look for termination/noise issues? Thanks!

Do you have access to a 2CAN? If you do you may use it to help diagnose the problem. An o-scope will not tell you much unless you know how CAN operates, the 2CAN however can diagnose if your CAN connectivity is the issue.
