I have a 2006 F-350 4x4 Dully 6.0L Power Stroke Diesel. Just got the EGR delete kit put on and SCT Programmer. The other week I had a battery go bad and always had to have someone jump start me I replaced both batteries in the truck. Everything was good then a couple days later my coolant reservoir got a hole in it and overheated the truck but soon as I notice the gage I turned the truck off and opened the hood to let it cool down. I ended up replacing the coolant reservoir, thermostat, top radiator hose, and the fan clutch. Then after all that the truck ran good for a couple days. But now when you start the truck it shakes at idol and when you drive it. So I brought it to auto zone so they could run a test on it. It through 4 codes: PO267- Cylinder 3 injector circuit low, PO683- Glow Plug Control Module to PCM communication circuit, PO672- Cylinder 2 Glow Plug Circuit Open, PO675- Cylinder 5 Glow plug circuit open. I was told by a diesel mechanic with the low voltage from the bad batteries and were the truck barley over headed it might be the FICM went bad so I checked the voltage coming out of the FICM and it still pushing out 48. What would make these codes come up all at once and make my truck shake when you start it and drive it?

 

Moved to 6.0 forum.

 

You can have 48V out of the FICM and still have a bad FICM.

 

Is there any other ways to test the FICM to see if it is bad?

 

Did you check it cranking and running. It would help if you had a scan tool that will read the truck

Here's some good trouble shooting for the FICM without a scanner
