I would bet this attached bulletin is your situation. Are you still under warranty?

Thank you for the bulletin. I finally had a chance to look into this. Vehicle is outside of warranty, so trying to figure out myself before bringing to dealer. I not exactly sure where this wire is located. The photo isn't clear what panels in car to remove. If it's the panels in back of vehicle near the roof, what about the small airbag compartments located those panels. Also, when found how is the LAN wire fixed, just tape like a regular wire.
