WOW....

toedtoes, this thread is becoming an educational event. That After Run System is for sure not a normal vehicle thing. First, does everyone read the manual that closely? Second, not knowing all the background on Busdrivers situation, could there be a temp sensor malfunction and it engage the After Run System?

Wonder how many dealers even know about such a feature.

Then comes the, if equipped. Not sure if GM still uses the RPO code feature, but how does one know if your truck has this After Run System feature?


Yeah, it really surprised me too. And I suspect most dealerships don't know about it.

For many owners, it would probably never happen. But for RVers, this is a BIG deal.

I wonder how many folks think they must have hit their fob when the truck actually activated this feature.


Well, Busdriver doesn't have the after run system as his truck is a 2019. The after run system was introduced for the 2020 model year.

If this happened the one time and I had my key's in my pocket while I was snoozing on the couch, sure wouldn't be posting about it... Get on with life.

Found a thread with this quoted from a 2020 model manuel:

"AFTER-RUN SYSTEM (HD Model)

HD models are equipped with an engine cooling feature that may be required to run after a heavy towing event. The After-Run System will keep the engine running, or may restart the engine, for 10–15 minutes to ensure the engine and related components are properly cooled. See Driving and Operating in your Duramax Diesel Manual."

And

Intended Vehicle Use: After a Heavy Towing Event
If equipped, when the vehicle is turned off after towing heavy loads, the system may automatically restart the engine. A chime will sound and DIC messages will display. The engine will automatically turn off after 10–15 minutes of run time or if enough cooling has occurred.
If the DIC messages display after the vehicle has been stopped and placed in P (Park) with the engine still running, remain in the vehicle with the engine running until these messages no longer display. It may take up to 15 minutes of idling. Do not park the vehicle in an enclosed area if the messages display.
If the system determines that the engine should be restarted and the ignition is turned off, the engine will turn off and then automatically restart. If the engine is restarted, DIC messages display and chimes will sound. The vehicle cannot be shifted out of P (Park) unless the feature is overridden.
Never leave occupants in the vehicle, and always take the keys and lock the doors if you must leave the vehicle idling. Some local laws prohibit a vehicle from idling unattended. Always remain with the vehicle until it automatically turns off. This could take up to 15 minutes.
If the system determines that the vehicle was not allowed to restart, or if a condition such as an open hood has been detected, then DIC messages display and a chime will sound. To help with system performance, either restart the engine, or if the engine is not running and the hood can be safely opened after one minute, open the hood to allow cooling.
If the system has automatically restarted the engine, the vehicle cannot move until cooling has completed and the engine automatically turns off. Overriding this feature will allow normal vehicle operation. To override, start the vehicle as you would normally. Then either drive the vehicle as normal or turn off the ignition if you must exit the vehicle. Opening the hood will prevent the restart or will turn the engine off when this feature is active.



Mayne his truck left his garage without him knowing on its own, went out and towed a large excavator up a 10 mile long 10% grade, then returned, garaged itself, and decided it needed a cool down?

I don’t know about the newer models but our 2014 GMC will remote start just fine with the doors open.

Are you sure?? One needs to lock doors first, sensors would sense door open. Now I need to test!

Interesting, on older diesels there were add on devices to do this.

I couldn't find a introduction year for the system - that's why I posted that it came from a 2020 model year manuel.

It may not be why this happened to the OP, but how many folks with a 2020 or newer truck know about it?

I do agree, if it happened once with the fob in a pocket or purse, etc, I too would assume I hit the fob. But, ifthe fog was sitting on a table or hanging up, I'd sure be checking for answers. I wouldn't just blindly accept a serviceman's "it must be a nearby wifi signal" as gospel (and I grew up in a dealership and serviceman family).

Just tried it again. Doors lock fine with the door open. Then remote start is fine too.

Our 2015.5 GMC 2500 and our two other vehicles (Acura and mercedes) with remote start won't activate remote start unless the doors and trunk are closed and locked and the hood closed and windows up and no CEL.
