Hey all.

I have been reading several of the threads about the FICM repairs. I am working on a 2004 International VT365. I have been recently been getting a DTC 525, Injector Circuit Driver Fault "M", and will occasionally get a Low Side to High Side OPEN on one or several injectors at a time (this one must last only for a second or so, as it always shows inactive when I notice it on the computer). I am monitoring on a laptop with Internationals MAster Diagnostics software via a Nexiq interface.

I called the guy at AR Auto Group in Broken Arrow, OK, and he seems to think my problem is more than likely in the logic board and not the power supply. (I flowed the solder joints for the capacitors with no change in rough running condition). Not sure of my voltage output because it is a huge pain. The ECM is on top of the FICM in these trucks.

Now my question. What is the difference, if any, between the 7 screw type and the 4 screw type modules. My FICM is the type with the seven screws. I know I can't swap the logic boards between the two, but can I use a complete 4 screw type module in it's place? I think I know where one is located, but am not sure which one it is.

Thanks

 

Hmm,
You could use a Scanguage II with Xguages to check
if it has an OBD2 port. But and this will be a bug BUT
your going to have to find out what Xguages to program in
because I don't know if the ford ones will do the job. Maybe
one of the Ford techs will chime in on this one. Or is this in a Ford ?
If it is then that is the way to go.
2nd plan is call Ed @ FICMrepair.com People send a lot of
work to him and are very happy after.

No OBD2. Medium and heavy duty trucks use 9 pin CAN bus protocol.

The truck is an International 4200. The FICM is the same as on 6.0L, (at least cosmetically). As far as I can tell, they probably went to the four screw type at the same time if not before the Fords did.

I just need to know if I can use a complete 4 screw type (if that's what the one I found is) in place of my 7 screw type. I would think the factory programming would be the same as in Internationals. It is the same injectors, etc as in the 6.0L.

 

You are going to need to call Ed
FICM Repair.com - Your Source for FICM Repair
Best I think be done at this point.
Someone else may know more.

I installed my FICM yesterday. Got the premium rebuild and the Atlas 40 tune. I have been having brutal cold start, low power and crappy fuel mileage for 2 months. Plugged it in and wow, seems like a different truck. Very happy with ED's work.BTW if you take yours out don't break the clips like I did!

 

It doesn't always work, but a 9 PIN CAN Buss to OBD connector can be used. Not sure about International, but sometimes works with PACCAR trucks.

Wait a minute IDK if it cuz you have a International Diagnostic stuff or what

but P0525 is not a FICM DTC for a Ford its not even a Diesel DTC for ford

Medium and heavy duty trucks use manufacturer specific DTC codes and not a universal system like OBDII
