Subject: Can someone run my NH DEF codes?

Wallis, TX

2012 CR 8090 threw some codes then de*rated itself.

First was E-0907-07 DTC:07C

Then E-1757-03 DTC-14F

Then about a minute later SCR 007

A few minutes later E1753-03 DTC-31D

Then finally SCR 008

Dealer said to check filters which were relatively clean. (Just a couple small bits of trash)

Any ideas? Dealer is trying to get a mechanic out there but it's Saturday. ERRRR!

The E0907 code indicates that the DEF system did not build up pressure after startup. The E1753 fault code indicates that the DNOx module did not power up properly (fuse? IIRC, the fuses for the DEF system are back by the engine around the hydraulic tank). The E1757 indicates the engine is in a derated mode due to the DEF system problems. Not a lot to give you, but its a start. Good Luck!

This happened after running about 8 hours, engine never turned off. And,,, according the the diagnostics screen the def system had 72 psi.
