DEF Level sensor code 1669

I have a 2011 Phaeton 40QBH and we are stuck here in a Cummins repair facility Olympia WA with the amber and red engine lights on. The code says the DEF level sensor is faulty or the wiring is shorted. The techs here have replaced the sensor but the fault remains. The 5V fuse is blowing and we are unable to get any wiring info (weekend)
Any info or ideas appreciated.

This is probably not going to help now but as far as contacting somebody during the weekend, Valley Freightliner up in Mt. Vernon is a 24-hour shop on the weekdays and closes at 5:00 PM on Saturday and Sunday. They are an FCCC Oasis shop (emphasis on accommodating motorhomes and I believe the only Oasis shop in Washington state) and of course will have all the up-to-date wiring diagrams, etc. If they're not busy, they will answer questions and troubleshoot a bit over the phone (or at least they did years ago when I called them). Their address, phone number, and hours: click

Valley Freightliner will also have other locations and does have a shop in Olympia ..actually in the Tumwater area (click). They will work on motorhomes although they are not a designated Oasis shop and are also open on the weekends. They also have a big facility in Pacific (between Tacoma and Seattle --click) that will work on motorhomes.

I'm assuming your Tiffin is on a FCCC chassis.

edit: Valley Freightliner in Pacific is open until 2:00 am 7-days a week
