Parked ReGen

Engine and exhaust temps have to be at a certain range before it will allow a regen... Many other things also like park brake set, in neutral, clutch not depressed, ECT.

If you tried to regen right after starting the truck then I'd bet the engine and exhaust temperatures are not hot enough yet... Let it warm up for 15 mins or so then try again. This may require restarting the engine a few times if it is wanting to auto shut down sooner. But you can probably override that by driving around for 15 mins... I have yet to see a truck that will auto shut down while in motion.

 

Start the truck and let it idle, It should automatically preform a regen.

 

Stupid question, whats up with your DEF fluid? It may be contaminated or other problem. The trucks today will not run when out of DEF Fluid in the reservoir.

Secondly, do you have a breakdown plan?

 

Its shop time. Keep overriding it and your repair bill will get more expensive. Probably have an active fault keeping the system from doing a regen.

 

Have you tried holding the override and regen buttons down for about 10 seconds to see if it will go into a parked regen? That worked for me when I had a similar problem.

 

There is a way to clear some faults by turning the ignition switch on and off several times ( 6) and then turning it to the on position, wait 30 seconds and then turn it to start. Check with the Fleet Customer Service Dept at your Dealer for details.
