no problem
Technician: Mike Mcmillan, Shop Foreman/Triage Tech replied 2 years ago
The fault code you have is for cat efficiency. There are a few different things that can cause this issue. I would make sure you have no charge air system leaks. Make sure there are no exhaust leaks. If you are using a service tool then look at the 7th injector adaptive factor. If it is maxed out then the injector would have to be replaced, then reset and a regen ran. If all those check out I would replace the injector and regen the unit and make sure your t2 and t3 temps are in the 850 plus range. I hope this helps. Thank you

how do I do a reset and regen?
Technician: Mike Mcmillan, Shop Foreman/Triage Tech replied 2 years ago
You can command one in the dash if the soot level is high enough. If it is not then you will have to do the reset and regen with a pc
