    Default Ford High Idle Controller

    I've got a Ford deisel ambulance with a Ford High Idle controller I've never seen. We can't figure out how to make it work or find any info on it. We bought the rig used from a bank.

    The controller is a box with four buttons across the top, one of them has the FORD logo on it. Four arrow buttons also run down the right side. There's an LCD screen on it that displays the idle speed. It's mounted on the doghouse.

    Anyone know how this thing works?

    Thanks,

    the ford oval turns on the system. but in order for it to work the unit must be in park and the parking brake set. the up down arrows give you the chance to raise or lower rpms manually as needed. the other buttons on the top are some preset rpm ratings. hope this helps and with the website it should work fine. let us know jeff

    We had one in our 2003 Mini-Pumper, but it ended up getting removed because it did not work properly when using our generator (I think that's what it was). The manufacturer had it removed and tied the high idle into the parking brake. We set the parking brake when we get on scene, and if the voltage starts to drop, the high-idle will kick on to boost it, run for a little bit, then shut off. That way you don't have the engine roaring when it doesn't need to.

    Any diesel engine when idling for a long period should be bumped up to at least 1100 RPM probably. This is because the cylinder walls cool down so much at low idle they actually start to get washed with liquid fuel and the lack of lubrication can prematurely wear the rings, and in some cases (even on modern engines but not particularly the Ford Powerstroke) it can even be enough fuel to start to dilute the lube oil. Additionally keeping the idle elevated helps the alternator put out plenty of power and keeps the air conditioning working better, if applicable.

    The one Ford idle controller we have is programmed to come on whenever in park and the brake is set, and it has a minimum speed, and additionally it increases RPM some more if the voltage drops too low.

    Thanks to all.

    Got the manual off the Ford Fleet website. Reprogrammed the idle to work off the parking brake, and it still don't work. (It was programmed so that you had to push a button on the controller.)

    Come to find out, the idle controller works off the PARKING BRAKE dash light circuit, and that don't work.

    So, once we get the dash light to work, the idle should work.
