I woke up this morning and turned my truck on and noticed this.


I haven't been able to idle my truck overnight as the temp wasn't reading low enough and setting the cruise and idling at a higher rpm wasn't letting it idle either. I called into maintenance just to get some answers and they said it's just the emissions systems. Could this cause further issues?

That happens to me once in awhile also. It's likely just a ghost symbol, and will go away on its own. The shop always says my truck checks out fine.


Hours Of Service

HOS refers to the logbook hours of service regulations.

The engine light in my truck also refused to go out once; after driving for a day looking at it, I called SEM and got the same response. They added that I may be asked to do a manual REGEN soon; I never had to perform the manual REGEN, and eventually the light just went out.

Pete, because the truck did an automatic regen while you were driving at highway speeds.

I’m looking at the same light as we speak. I also get a warn engine light occasionally to go along with it. They always go out eventually.

I’ve put it in the shop twice now for it and the conclusion we keep coming to is it’s a computer glitch. I’ve also never been asked to do a manual regen.


Transportation Worker Identification Credential

Truck drivers who regularly pick up from or deliver to the shipping ports will often be required to carry a TWIC card.

Your TWIC is a tamper-resistant biometric card which acts as both your identification in secure areas, as well as an indicator of you having passed the necessary security clearance. TWIC cards are valid for five years. The issuance of TWIC cards is overseen by the Transportation Security Administration and the Department of Homeland Security.

The amber light isn't too much to be worried about. Mine stayed on for a few days after i did a manual regen.

When I idle my truck for to long, I will see no fuel when full, ABS lights and check engine lights. It's the trucks way to trick us into not idling.

Call SEM. That's what they're there for.

So I let it idle overnight and went to sleep, just woke up with the light still on, shut the truck off, waited 5 mins and turned it back on, check engine light and the active fault is gone.
