2018 Cascadia idle override

@Fztrout

So according to this, if I'm reading it correctly you shouldn't see a light.



So in reality, the whole point of Auto Elevate is to prevent you from having to do excessive regens by simply keeping the ATS hot enough to burn off any excess HC so it won't store in your DPF.

 

This company is ALL about money they give no #### about you. They make money regardless if you quit. If you stayed the 9months they made more than what they would have made with the tuition costs if you quit early they charge you 5k + 2k in financing so they make money off of there. It's just a cdl mill, get you exp and run. Trainer wouldn't be so bad if they actually stopped the foreigners that can't understand English and the maniacs from passing orientation. I make 1.2-1.5 a week with trainer but it's no worth it with someone of these people they let pass.

 

Pull off the driver side smaller mirror, you will see a sensor in there. Take it out and by pass it with a paper clip and your good to idle.

 

I have a 2019 freightliner with this idle optimizer and it dose not keep the truck cool for long, after it shuts off the temp has to go to 75 degree before it kicks back on for about 4 minutes then cuts off again! And every time the truck cuts off it shakes the truck so bad it wakes me up ever #### time!! Will not ever buy a freightliner again! And will not work for another trucking company that has just freightliner! KW's are the only way to go

 

You can change the temperature and the variance temperature 4F 7F or 10F. You get use to it starting and stopping. You can turn your heat dial and so it blowing less cold air. That will make the engine run longer because it's always trying to reach a lower sleeper temperature.

 

If you have a 2018 Cascadia in the old style hood, the ambient temp sensor is in the drivers side mirror case, behind the lower mirror, on the outer edge. Pull the plug and idle away. I've done full 34s idling with zero issue (my company doesn't care about idling, I just haven't had a chance to get to a dealer to change the setting in the ECM)

Pulling the plug will set an engine code. Light goes away after five or six full starts.

 

There are actually 3 temperature sensors that work in conjunction with each other. One is on the underside of the drivers side mirror, another is inside the cab and is in different locations depending on what specific model of cascadia it is and what HVAC control module you have in the bunk of which there are 4 different control module types/styles - on 2 of them the cab sensor is on the module it self, in another it's under the dash above the gas pedal (up inside a tube) in another it's by the dome lights in the ceiling. The 3rd sensor is on the front of the truck behind the radar.

What temperature allows the truck to stay running is determined by the company. Freightliner programs the low and high temperature as the company requests. Changing these temperature settings requires a login to the computer system only authorized technicians have.

It does. As I said above what outside temps determine if the truck stays running or not is set by a mechanic with a login that enables them to do it.

Both the company and freightliner know everything the truck does. It's logged and when a sensor fails (which tampering with the sensors by removing them does) it will send an alert code saying it's malfunctioning...so it might get looked in to...

With all that said there is still hope to get it to idle no matter what the outside temperature is depending upon what HVAC control you have in the bunk. Hot or cold if you put it on A/C mode and set the digital temp to as low as it can go you should be able to use the knob controls to control the actual temperature and the truck will actually start it self and stay running.
Mine is a 2016 cascadia II and this trick works.

Take heed to what other people said though. Your company will know you idled. Don't do it for long. You really don't have to trick it at all. I haven't had to. If you put the ignition key in accessory, turn the cab controls off and the bunk override on up front the bunk heater and A/C just works. Temp can be controlled by the knobs in the bunk HVAC controls.

The bunk HVAC will run without the engine running. Your not going to drain 4 batteries dead running the bunk HVAC for the 5-8 hours we get to sleep.
The truck does not need to idle. That's why this feature was introduced. I believe what needs to happen is both Freightliner and companies need to share with drivers how to use the HVAC as it's designed so we know and don't have to or even try to tinker with it. It does work without idling the truck burning fuel away sitting still. The 2018's and 19s will actually start and shut down the engine as it needs to if you go through the menus with the steering wheel buttons and turn the temp control feature thing (I forget what it's named) on.

They key has to be in accessory in the 2016 models, I believe it doesn't matter what position the ignition key is in in the 2018 and 19 or models.

 

I'm trying to figure out Optimized Idle also on my 2018 Cascadia. I don't think it is programmed into the computer. I saw a blog that mentioned that OI might need to be turned on at an authorized dealer. Don't know if you know the following, or if anyone has said so far....you can over ride engine shut down by turning on the cruise control and pressing either the + or - button. You can also adjust the idle speed. I have mine set to just above normal idle and the air is good and the company doesn't say anything about too much fuel use/idle time.
