2016 freightliner cascadia Evo DT12/eCoast

Can depend if you have the newer integrated detroit powertrain with "intelligent powertrain management 4" which has a built in GPS of all the most major freeway grades.

It will run completely differently than a non IPM equipped truck because it is evaluating the grades in front of you to optimize MPG.

This only applies to cruise control of course, so if occurring outside this then disregard my comment.

 

E Coast only works with cruise on. If you are driving against the governor without cruise on, and are going downhill causing you to exceed the truck's governed speed, it will coast in idle mode regardless of how hard you are pushing on the go pedal. Also, it will not display E Coast on dash during this time.
If you are seeing E Coast displayed with cruise off, that's a new one on me. But then again, these trucks can be ordered with all sorts of parameters in the programming.

 

Put your foot on the fuel pedal to disengage it

 

The problems that I’m having on my dt12 is that sometimes e coast will work then it will take about a month to work

 

Did you find out what was the problem

 

The engine break will cause it not to engage sometimes. Also where did you get your manual?

 

I have the same thing except I don’t have camera/gpson my truck

 

I believe when ur truck is close to dpf regeneration, it wont put into ecoast..
