2012 Cascadia Overriding the 5 min idle timer?

Try just taking off the tractor break and bump the idle up that way. Or tuat doesnt work there maybe a temp sensor near your 5th wheel hand warmers in a sock over the sensor will trick it to thinking its over 100 degrees out and it should stay running

 

Really depends on how the company has it setup I think.

Mine has it I can cancel it whenever it comes up with it comes back EVERY 5 minutes.
Cruise Control works when Idling but it doesn't stop the timer.

I can release truck brakes and set the Trailer Brakes only and I get a 30 min timer in that case.

 

Did you look for a temp sensor near the fifth wheel?

 

if your bunk heater kills batteries in 6to8 hrs i would get batteries load tested . also if you run reefer you can run a jumper wire off reefer you only need a positive truck is already grounded to trailer

 

I used to work for Pepsi, and our trucks did that as well. I was in a Freightliner business class. I waited the five minutes, when the check engine light started flashing, I tapped on the service brake. After tapping on the brake, the truck would stay running.
