Good to hear....We bought 2 new ones and they haven't been on the road yet....Just waiting for the gravel haul to start. I have to say that we took a leap of faith when we purchased them since we were not too familiar with the new line of Macks. Hoping to start pounding the roads this week..

If you want I can scan the operating guide card and post it for you.
Need some guidance with an after-treatment fault: P110286
in Modern Mack Truck General Discussion
Posted
Truck is a 2013 CHU613, MP8. 2010 emission and OBD 2013
Faults are: P20E892 reductant pressure too low or incorrect operation
P110286, reductant pump "A" control circuit electrical signal invalid.
Truck has the derating timer on when it comes in but faults are inactive. I followed the Tech tool diagnostic sequence and all tests good (only thing is I didn't use a load to test the grounds, just the Ohm meter).
These codes have come in randomly in the past couple of months. Always inactive when truck shows up and tests are all inconclusive. Should I concentrate on the ground side ?
Thanks
