DEF PROBLEM

My dash is lit up like Christmas air alarm constantly on gages and tanks are full. Codes come up are on above posting above

 

What computer got installed? The first thing & a simple step, I would recommend turn off your battery disconnect switch if equipped. If not equipped I would disconnected the negative battery cables all your batteries, to force a hard reset of computers. Just in past week of I plugged in Nexiq diagnostic adapter that was connect to laptop to do a forced regen and dash started lighting up like Christmas tree. Turned off the battery disconnect and and turned back on & rebooted laptop and after that was able to connect up Diagnostic link and do regen without problem. Also, post the last six of VIN for most accurate information.

 

Vin# FH7871. THANKS FOR HELP

ALL THAT SHOWS UP AFTER FORCE REGEN ON LAP TOP will not do manual regen bia button hold 10 seconds

 

Thanks for Vin. Your truck is EPA10 and the diagnostic steps listed in post #11 but on July 21, 2020 for SPN4364 FMI 18 and SPN 3364 FMI 2
will be the same for your truck, so if they go active again and you need to got down that path. Will be interested to know if disconnecting the negative battery cables for a minute or two 2 resolved the dash lighting up like christmas tree or not?

 

On fault spn 522213 mode 31 "LVD sense BAT/ Emergency power supply"
Troubleshooting Manual says:
On EPA10 vehicles this could be an open fuse D in the PNDB. There could also be a wiring fault between the fuse and the SAM Cab connector X21, pin 13.
However, on this wiring diagram it looks like it might be fuse B. Either way I would check both fuses B & D in Powernet Distribution Box (PNDB). The PNDB should under hood near the left firewall.

 

Will try negative disconnect tomorrow. Thanks. Again

 

Just tried negative disconnect for a couple of hours cleared all but ABS light and brake air. Ran for about 10 minutes idle. Again check engine first 10 minutes later check Trans and truck down hill light. (What does it mean)

 

What is this light. It came on simultaneous with blinking check transmission b. For the record clinking check transmission light has been there since I bought truck at auction I had auction mechanic look at it with scanner he said something on back of transmission not to worry would not affect truck driving home. The truck was driven over 5000 miles and no issues with that sigal blinking check transmission light doing. ALL OTHER PROBLEMS CAME AFTER RUNNING TRUCK OUT OF DEF INSIDE MY YARD TWICE WHILE MOVING CONTAINERS IN YARD. PLAIN IGNORANCE BY MY EX DRIVER. NOW I HAVE A CHRISTMAS TREE EVEN AFTER FORCE REGEN

 

The Cascadia driver's manual & maintenance manual is available online & free to the public at:
DTNAConnect - Daimler Trucks North America
I recommend you download and read as it is very informative.
Your transmission is an Eaton so www.roadranger.com is a great resource.
On your ABS light, typically that is on after codes are cleared and once you drive over 5 mph the light goes out if you no ABS issues.
Your active faults should be able to be read from dash.
Did you check your fuses at the Powernet Distribution box (PNDB)?
