There is a FICM logic pwr PID that should be right at 12 volts. FICM main power should always be at 48.

Forgot, there's also a FICM vehicle power PID that be at 12 volts as well. Those readings are way off - they can't be right if your truck is actually running.

+1. I don't think vehicle would run with FICM main power that low.

Something is wrong with their equipment since your truck actually runs. There is definitely something wrong, and it just may be the FICM. BUT the results they are getting are not consistent with a running truck.

You should check it with a volt meter and see what you get. The procedure is simple and it's in the Tech Folder.
