Just trying to find a source to find out where and what colors the cruise and accelerate wires might be, also what signal they need to turn on. Trying to get the remote start to turn on the cruise and accelerate to make the high idle work from the remote. If the ebrake is on and the cruise is turned on it idles up to 1000rpm and every time the accelerate button is hit it goes up 100rpm up to 1500rpm. Just trying to see if this is capabale from the remote start.

i have recently seen this thread regarding higher RPM idle. try going a search for dodge rpm, it should pop up somewhere.

its a bussed signal out of the steering column, idle up feature via remote not possible

Pardon my stupidity.... but what purpose would this remote controlled high idle serve?  -------------

it allows you to idle up the engine, most diesel motors at idle produce very little cabin heat since the coolant barely warms up. also at idle when the ambient air temp is below 60 degrees fahrenheit they use a heater grid to heat up the intake air, which draws ALOT of current you can see the headlights dim, etc. Idle up feature allows you to compensate for some of that.

Thank you. Does this idle up feature normally work when started with the key? If so I'm wondering why it does not under remote start?

kartune man, you got me thinking about that too, if you can do it with a key, during remote start, it should do the same. as for the power, your alternator shoulod provide enough for the car to run with full electrical load.

The high idle helps warm the truck up faster and to maintain heat while its idleing, also its hard on a diesel engine to sit at idle for to long because it is not burning the fuel properly were as at an high idle it is. To make the high idle engage start the truck set the ebrake and then just hit the cruise button to turn it on and the high idle is activate and it goes up too 1000rpm and then to increase it hit the accelerate button and each time you do it will increase 100rpm up to 1500rpm. I thought if the cruise and accelerate worked of a negative or positive pulse then this could be done through the remote start as it has to aux channels, but if it works on a bus then this would be alot harder to do.

The only real reason I would want to do this from the remote I guess is because of laziness but I guess having command start is the same thing though. Just want to be able to start the truck and then increase the idle from inside the house and then in 10 minutes or so the truck is warmed up and ready to go instead of still freezing cold.

Most unit (like astro and compustar) double the runtime for diesels, would this programable feature not be sufficiant? Simply understand you need to start the truck "earlier" than you normally would I don't know? -------------

Unfortunately on most new diesels utilizing a heater grid the alternator makes just over 12 volts (12.4 on average) while the heater grid is active while at idle, not the 14.4 volts you would typically see. I am a chrysler technican (as well as a Toyota tech) and I am in the middle of North Dakota (temp last nite was -30 before wind chill) we standardly enable the idle up feature on the diesels here as part of the new vehicle prep, once the intake temp is at 60 degrees or above (when the engine warms up) the heater grids shut down

So if this feature is active, it should work during remote start....correct?

The grid heaters I dont think are a problem I got good batteries and have never noticed the that the truck was suffering from not enough voltage to properly start and run the grid heaters while it is idleing. The truck has a bit of high idle built into the ecm that it will idle up to 800-900rpm when idling while its cold out. But the high idle feature I want to enable has to be physical done doesnt matter if the truck was remote started or not I have to go in the truck and increase the idle with the cruise buttons, thats what I want to do from the remote so I dont have to go to the truck and increase I want to do it from inside the house. It has a compustar 8000 and it really doesnt matter what the runtime is these diesel engines take for ever to warm up unless they idling around 1200rpm and its harder on the engine idling at low rpms for a long period of time.

So does anybody know how this bussed signal out of the steering column would work?

yes it sends a command to the FCM ( front control module) which then enables, either cruise or high idle, the command would have to be done via a data module since I know no other way to duplicate a data command other than that
