Check Engine - Code 3521 FMI 11
So, we were leaving the west suburbs of Nashville this morning headed to Dallas. Figured a 3 day trip arriving at NIRVC for some work on Wednesday. Body repair and windshield replacement.
As we were heading west on I-40, the check engine light came on just before we were going to merge onto I-40/I-24. I had been at Cummins a couple of months ago here, so I took that exit instead and am currently sitting in their parking lot.
We're showing Code 3521 FMI 11. From what I've read, it is related to DEF. I've decided to overnight here in the Cummins parking lot. When we were here back in September for engine and generator service along with caring for the fuel rail recall. They allowed us to overnight, since they couldn't get both the service and recall issues cared for in one day.
If anyone as any insight on what Code 3521 FMI 11 is specifically, I would appreciate any input.
