DEF Pump Issue

Good Morning - Last week my 2021 Cascadia had new DEF pump installed in Albuquerque NM. The codes at the that time I had were SPN 5435 FMI 31. Repair shop guys said it needed a new DEF PUMP and we got it replaced.

New DEF Pump was installed on Monday, Truck drove from Albuquerque to Bakersfield CA. Load was delivered in Bakersfield on Tuesday Morning. Truck was not driven/started after delivering the load till Friday evening. After driving for less than 5 miles, Truck has CHECK ENGINE light on, DEF is also leaking and I checked in Samsara it is not showing 3 codes with SPN 4374 FMI 0.

Please suggest what is going on.

 

Good Morning - Truck is still parked in yard and we have repair shop in the yard. Will go today and see what is going on and will keep you posted.

 

There was DEF pipe that came off, this is why it was spraying all the DEF on floor. Now we have fixed it and 2 codes are gone automatically but the main code which is SPN 4374 FMI 0 is still showing in Samsara. Check Engine sign is also gone but the solid yellow light is still there.

Any suggestions, Do I need to connect it to computer to remove the code?

 

Drove the truck for 10-15 miles and then parked on the side, removed the Samsara device from the truck, power shut off the truck, waited 10 minutes and started the truck. SPN 4374 FMI 0 Code was gone but now I see a new code below
