How to: Elevated idle control for 2008 diesels - Diesel Forum

SmokeyWren · 11-21-2008, 08:03 AM

Ford has included logic for elevated idle control in the powertrain control module (PCM) since the 2005 model year. It's called the stationary elevated engine idle speed control system (SEIC). But you have to hook it up to make it work.

The SEIC is not just for power take off control. It's also used to elevate the idle RPM for battery charge protection, or for extended idling in hot or cold weather so the heater/ventilation/air conditioner (HVAC) systems will do a better job.

Here is a link to Ford's procedures for how to install the bits and pieces to make the SEIC work in a 2008 SuperDuty truck:

That PDF is pretty involved. Can someone translate it into more simple instructions? For the Stupids like me? For an '08 F350 PSD Thanks.

Is the seic wiring directions for the 08, the same for 09 trucks?

I made the connection to activate the SEIC using one of the Auxiliary Switches. It is a very simple connection (two wires), if the default RPMs (1200) will be used. Thanks SmokeyWren for the useful information.

I did the high idle mod but i want to add a potentiometer, after looking at that diagram it show the green pto_rpm wire being grounded which I understand but what I dont understand is it says pwr grd 4.75k, what does the 4.75k mean, do i need to add something to the ground or something
