FICM Test
 

06 6.0 PSD Automatic


Opened up the box and my 4 screws are up and down not right to left. Is it the bottom screw to use for the test?

Up and down? They should run side to side of the truck, not front to back. If you have 4 pins, test the one closest to the drivers side. Red probe on that screw, black probe on the negative terminal on the battery.

Yea they dont run fron to back but are up and down

Like that so not sure which one to use -

Take a picture please. I'm not sure what you mean by up and down. The FICM is mounted on the valve cover, so it sits at a bit of an angle. The pins run from side to side of the truck, in line. The one you need is the one closest to the drivers side.

The rusty washers are to the FRONT of the driver's side valve cover - the screws are staged up and down

Another shot

the bottom one is the same as drivers side one, same thing... thats how they all look

Mdub & Powerstroke thank you both for your rapid response. The FICM tested fine:jump:

is the truck running bad?? why were you testing it?

Starts hard and runs rough until it warms up.

If plugged in starts ok but still runs rough until it warms up.

what did yours read if you dont mind me asking. Mine read right around 40v on a scan tool. obviously mine is bad. Just trying to rule out other things like the ICP and such.

Tested right at 48

Chances are it's even lower. Scan tools can only read as low as 40V, so if the FICM is actually 20V, the scan tool still reads 40.

Thats it...Just for shiggles im hitting it tomorrow with the multimeter. will post with results. I kind of want to see what it reads at now. you piqued my interest.

I'd be interested to see what it reads as well.

42 KOEO 33 cranking 38 running. So not to far off from the scan tool and still manageable plugging in right now at 17 degrees last night. Im kinda thinking about going with one of your 48v units if you cant do the hot one. It will probably be another 2-3 weeks before im ready though.

edit: cheapy multimeter...all i could get my hands on quickly. Ill hit it again after I get with a buddy of mine.

Definitely dying...
