1997 Ford F350, 7.3, 2 wheel drive. PCM part number F6TF-12A650-AYG.
OK the question is how to diagnose the PCM without codes due to the battery being dead?
I have it out of the truck and was hoping to see diagrams or schematics for use of a multimeter. I looked at all the fuses, sensors, etc. I need to know how to do this because the PCM is to expensive to get a diagnosis from places and/or I have to R&R the part.
That still may not be the issue. If I have to put it back in or anything I will do it. Please help. I did hook it up to a diagnosis reader, and tried a few times to erase codes that where not there.
Also, it gave me an error trying to erase the codes. I also tried this test on 4 other vehicles with this computer and it would erase codes even though there weren't any, without error.
