I have a 1996 F-350 4x4 cab and chassis truck I've recently bought and I am trying to make sure it has the correct ICM. It has an aftermarket ICM so I don't have the factory ICM for a number. It has and F6TF-AHA with calibration 6-98A PCM (7.5L E4OD). ICM mounts on an aluminum heat sink on the inside of the driver side fender.
If you didnt have the right ICM, you would likely have driveability issues and codes.
I would like to note, the aftermarket is not consistent with ICM color. They can be found grey when they should be black, and black when they should be grey. Meaning sticking to actual OEM motorcraft is the best bet. It doesnt help that internal ford resrouces were incorrect on these as well!
I am having drivability issues, that's why I was asking. I tried reading through some other treads on this topic and didn't see a lot of info about the ICM's for 7.5L engines. I am going to order a motorcraft ICM, I just wanted to see if anyone had better info because no matter where I look the part numbers up (Ford, rock auto, motorcraft, etc). it comes back as the gray (OEM) ICM for my application.
You will get a code P1351 on a 1996 for IDM failure if you install the wrong color module
The correct black Ford module (with the IDM circuit) is F1SF-12A197-C1A
Black icm 96 e350 7.5l
I can only find the gray one in the vehicles been running with the gray one for about a year and I purchased another one which was great and it does run but I seem to be having overcharging issues and I was wondering if this is possible due to the wrong ICM
Any help would be appreciated thank you
Not the ICM for the charging problem
The only difference in the modules, is the black ones are designed to work with the Ignition Diagnostic Monitor (in the processor) of 1994 and newer vehicles
So, the old grey ones (1993 and earlier) have no IDM circuit and will cause a code 212 in vehicles designed to run with the ignition diagnostic monitor
