Frustrating Idle Cutoff

Good question and I hope someone can answer. I have a 2015 cascadia and NOTHING I have tried can keep this thing going.

 

Guess I am one lucky swift driver. I drive a 14 IH prostar. It allows me to idle as long as I want to. QC says intertrip idle and intertrip idle violation but that is all. But I do get those annoying message saying I am one of the higher idlers, too bad when it's -10 outside and my stupid bunk heater shuts down after one hour, I am not waking up every hour to idle it then wake up to turn off again

 

What I've heard and this seems to be true on my 2015 Freightliner is that the idle is temperature related. It will idle above 75 and below 30 but not in between. When it's in one of those ranges, all I ever have to do is hit the gas when the check light starts blinking then it will idle forever provided the temperature does not drop or rise pass one of those thresholds. Between 30 and 75, there is NOTHING I can do to make my truck idle.

 

While not the best way; have you tried releasing the tractor brake while leaving the trl brake on?

 

These trucks will turnoff no matter what, even in traffic jam if you are stopped too long and temp is out of range, have to bump gas pedal/brake/eng cutoff bypass switch etc to keep running. The setting on mine is 15-70 degrees it's a true pita. If yours has the temp sensor on rear frame and you park next to a truck with exhaust dump on right side of truck or APU unit blowing warm air it can fool sensor on your truck, I have done this since sensor is on left rear of frame line her up with their exhaust and you can idle while they are there or not so just a tip.

 

What fairshake said. They shut off even if you're stopped in traffic. Mine is set between 30 and 75. What does the temperature sensor look like?

 

It looks like a light bulb plug/socket on mine near the inner frame by rear left drive tire, might have a plastic zipper band around it to secure. Could have one in front too, YouTube shows where they are. So when it gets cold but not cold enough and you have to sit due to no freight or bad weather you are screwed! The bunk heater with 4 fresh batteries will last 12-14 hours at most running the heater alone not your tv/laptops included, even less the colder it gets. I have a routine of sitting up front mashing the shutdown bypass switch while looking at cell phone for an hour or so to get a good charge again. We shouldn't have to put up with this bs.

 

Exactly what I have to do. I think you have it worse though. On Swift trucks, the low temperature is 30F. That or below and it will idle. Problem is, I always seem to be in areas that are around 34F or so. And yes, when we're stuck, it would be nice to have power for our laptops as all of my movies, music editing program etc. are there and passing the time becomes easier with entertainment.

 

Does it also shut off when the brake is pressed in continuously?

 

I've got the warning that it's about to but I'm usually sitting in traffic when that happens so I haven't waited to find out.

Last night, it got below 30 where I am so after several restarts and hitting the gas, it finally remained on.
