2017 Freightliner Problems

I have an orange engine light on in my 2014 KW T680 all the time. It's been that way for months. I checked the manual and it's not the actual check engine light but just a "notification" light.

The other day when I was stuck at my shipper with two bad trailer airbags, I was playing around with the display.

Turns out the notification was about my fuel level sensor. I can look at active "warnings"- aka the check engine light (serious problems) and "faults"- the blank engine light (minor issues that don't affect major systems or functionality). There is a common problem in these Kenworths that the fuel level sensor will stick open, sending a message that the fuel level is low. My fuel gauge bobs up and down once it hits about 3/4. It's done that for awhile, but road assist said that it's not a major problem and they can fix it at the next service. I just keep a closer eye on my fuel levels. Hence the fault.

I said all that to say, check your display menu (if you have one, not sure about the FL) and see what pops up and communicate with your road assist about it. It may be a simple, non-threatening issue that is a simple fix.

Yes I checked that when I had the light, but it didnt list anything. Said, 'no active alerts' or sonething of that nature. Oddly enough, it cleared after the next fuel stop and hasnt c Ime back on.

Thanks for all the replies. I'll check the display once my co driver is done driving . But yes, it is a big deal going up even a small grade loaded and the tranny wants to shift from 10th to 12th gear while I'm floored and let the rpm's drop to just a little under 1,000 and start to big down.

I'll have to look for the book. The little light is in the shape of an engine and has no words or lines or anything. Just a blank engine.

According to the book an amber light with no words, just a picture, means an emissions related fault. It says to see the engine operation manual for details. Sorry that's not much help, it's all I got.

So my company just gave me a brand spanking new 2017 freightliner cascadia with only 8.4 miles on it. First problem is it's an automatic. I suppose I can get used to that but the second problem is that I now have 900 miles on it and the tranny won't come out of eco mode. Makes it very inconvenient. And there is an orange engine light on. Anyone know how to solve this issue so I don't have to relay off my load and sit at a terminal?

Nope. You're right. They are so concerned about mileage they kill off any performance.

I drive a different tractor on a daily basis. Sometimes the 680, other times the Volvo with D13, Cascadia or the manual KW or Volvo. My favorite is the manuals.

The autos are all programmed to shift at 1600rpm regardless of the terrain. Trying to merge into traffic, oops, let's shift at 1600rpm and drop it down to 900rpm at 50mph so we lug into traffic.

35K up hills? No problem! You can go 25mph. Just make sure you turn your hazards on early.

With programming the way it is today I KNOW they could program each gear for a different rpm. They are just too lazy to do so. So we suffer at 65mph and no torque up hills. C'est la vie.

Hi it could be you have run low on def ( ad blue) that can make your truck run low on power ! Or it do on the trucks that run in Europe just a idear

I don't have one of those, unfortunately, but doesn't it have a display screen? I think there's a page that shows any fault codes so you can see why the engine light is on.

My 2017 freightliner had the malfunction indicator light (engine light that doesn't say check engine on it), which in the manual indicates an emissions related fault.

I notified road assist and they said just keep an eye on it since nothing seemed wrong. The light went off after a day or two and hasn't come back.

I'm still getting used to the auto. It's ok but I prefer the manual. I read in the manual how to activate the performance mode, but I think prime has it turned off on the company trucks. It is annoying when you need to do a speedy takeoff, like busy crosstraffic that doesn't stop. Manual shifts help a little bit, but not nearly as quick as I could take off with the 10 speed.

I'm having this issue right now. I just did a parked regen. The light went off but now the engine light came on. It's just a solid yellow engine light with no check in it. What should I Do? What does it mean?
