DD15 idle shutdown timer

Well, I thought I did. Im about determined my truck will not idle unless the outside temperature is either below 20 or above 80.

But, am I understanding you correctly that your truck's ECM is set up the same way with the 20, 80 stuff?

What did you mean by pushing the pedal down after the lights come on and before pushing the override button 3 times? I tried doing that, bumpin the idle up to a hundred rpms over normal idle, waited for the lights to flash, pushed the pedal down to the floor, let up and pushed the override button 3 times and nothing. After 3 minutes, the lights came back on indicating the motor was about to shut off.

How do you do that, with a laptop? If so, they supposedly have that stuff coded so that you cant without the password.

What do you mean by "ramp"? Are you saying that the rpms should increase by pushing the decel button once? Also, when you say to turn the cruise on, am I supposed to run the high idle or just tuen the cruise on and hit the decel button?

With mine, I believe it is. And if it is infact IS, I think thats how they get away with it because its not like my truck wont idle for en extended period at all, it will, but only if the outside temperature is below 20 degrees or above 80 degrees. If its below 80 or above 20, they figure you dont need AC or if its above 20, thats why we have the bunk heater.

 

Actually, I figured out what you meant about the rpm ramping up but isn't there more to it? I tried your trick last night but the lights still came on and shut the motor off.

 

See, this is why I feel the only way I can idle is when the temperature is either below or above what's set in the computer. It doesn't sound like your truck and even the other guys truck is setup the same as mine if you can pretty much idle in any temperature.

But, I highly doubt that the ecms are the same because the dd15 is way different from the 60 series. I could see some similarities between the dd15 and the dd13 but even in that case, I'm sure there are some differences within the parameters.

I wish it were that easy but they do this because I spose they feel that idling between those two temps is unnecessary and wasting fuel. I like how they think they know what I call freezin to death and burnin up.

England. I'm pretty sure that even as L/Os we have to put up with this is because we only have to pay for a portion for the fuel we buy.

But atleast when we're in houston in august and in wyoming in january we have no problem makin the truck idle. I mean hell, we're team drivers for petes sake. We don't idle that much to begin with but there's still times where even though its not blistering hot or freezing cold that we need to charge the batteries or keep them charged when we fire up the toaster oven. At least we have a little charging cable to hook between the jump posts on the trucks framerail and the reefer battery but sometimes that's more trouble than its worth.
