Please help to get home:(

Hi folks,
Today two engine lights, stop eng and def blinking pops up on my Cascadia 2017 390k mi. Truck derated to 5mph. Stopped at the rest area. All dealerships are closed till Tuesday. Also i got SPN 520372/16 fmi 14. I am 250 mi away from home. I stuck somewhere between Detroit and Lansing MI.
Tried regen twice, nothing
Tried reset codes shutting power for 15min and codes are still there and I cannot move.
Anyone know how to bypass deration of engine and get home. Yes i know that need to tow it to stealership but everything is closed until Tuesday. Please, any ideas? And yes researched a lot but no clue what’s the problem is. Everything could be def pump, def crystalized, def dozer, nox, scr. But main point is can i reset anyhow stop eng light to continue to drive?

 

Try to unplug speed sensor it's located on the transmissions tail shaft, good luck

 

Tried removing battery cables for 15 minutes?

Sounds like a tow is imminent.

 

I saw video on youtube but it is for manual transmission only it says. Anyone tried with automated trans?

These chaps may have insight.

 

I shut the switch. But not batteries

 

SPN 520372 / FMI 16 - SCR closed loop at maximum limit fault.

everything im reading online says it just needs a system update . Or it could be a bad scr all together.

I dont think u are going to be able to clear it without the detroit software

 

The funny thing that 2 days ago it happens first time and dealership at Indianapolis diagnosed this and updated also did 4 hour scr test. This happens again today. Whatta shame

 

Well, i guess i stuck here for good. I feel freaking sad fellas. But thanks for yall for responding that quick. Have a wonderful wknds.

 

Can u get a uber to a hotel
