HELP with No start issue; BPD 58v FICM bad?
I need some of the collective wisdom of this forum. PROBLEM: I shut my truck off at 8:00 pm Saturday night. It was running fine. Sunday morning I went to start it and it cranked fine, but would not start. My CTS Insight showed 0.0 FICM voltage. So, I removed the top plate on the FICM and tested it with a voltage meter per Ron's videos on YouTube (with key off, and then while cranking). Results = 0.0 volts. I checked the FICM fuse and installed a new FICM relay. Same result--0.0 volts.
I found the following trouble codes:
P0611 FICM performance (this code has shown up since I upgraded the FICM)
P1000 On-Board Diagnostic OBD System Readiness Test Not Complete (this code has shown up since I installed the CTS Edge Insight monitor).
P1378 FICM Supply Voltage Circuit Low (this is a new code)
U0306 Software Incompatible With FICM (this code has shown up since I installed the PHP Atlas 40 FICM tune)
So, it appears that my FICM is dead! Correct? What could cause this--why would my FICM fail suddenly? My understanding is that the FICM rarely fails suddenly, and that they tend to fail more gradually.
Please note that I installed a Bulletproof Diesel 6-phase FICM with the 58v option about 15 months ago. I also installed a Power Hungry Performance Atlas 80 FICM tune about six month ago. Could my FICM have burned up? What else could it be? I haven't pulled the FICM yet, so I don't know what it looks like inside, and I have not been able to inspect the wire harness. The only other thing I should mention is that about three days before this problem occurred I installed LED dome lights. Is there some way this could've caused a problem?
All input is greatly appreciated!!
