2018 Freightliner Cascadia idle control settings

Some will respond to holding cruise set and cruise up at the same time for fast idle.

 

Most times, the idle shutdown is set by outside temperature. If you feel the underside of the driver's side mirror case, you will find a small nub of plastic. That is the outside temperature sensor. Pull the outer edge of your small mirror all the way towards the door, then reach your fingers in to find the plug connection for that sensor. Unplug that sensor (you may need a flathead screwdriver). In a minute or two, your dash will no longer show an outside temp reading. Additionally, the "check engine" and "malfunction indicator" lights will come on. But your truck SHOULD idle from now until you run out of fuel, including idling up for regen if necessary.

This is on a 2018 Freightliner Cascadia in the older body style.

 

This may help.

Issue:
This is a new "feature" on all of the New Cascadia vehicles. It is called "inactive idle shutdown" and is present for fuel economy reasons. The feature will shutdown the engine after 45 minutes of idling even if the idle shutdown is disabled.


Solution :
To disable this feature, the CPC parameter : PG360 - Enable inactive shutdown -- needs to be change to "disabled". All of the New Cascadia vehicles will come from the factory with this parameter enabled.

 

It won't be long before the only controls we have are stop and go. My manual shift is disabled.

 

Thats awful.

 

Some of my 2011s had this"hidden" parameter, too. Drove me nuts until I found it.

 

I have a 2018 Cascadia too. Same issue, except mine has an APU. I’m so disgusted with the Economy settings on this truck, I’ve asked the company to trade it off with one of our Columbia gliders. #### truck only had 19k on it
