P1633 Ford - Will this code clear it's self? PCM mistakenly pulled and replaced.

Question

Hi, 2008 Ford F350 diesel with P1633 code. PCM low voltage if the Internet search is correct. I am thinking the fault was created when the PCM fuse was puled mistakenly (and it was) when trouble shooting the cargo light. Cargo light has been out for about a year the code is new. My scan gauge is unable to clear the code even for a moment. So is this a hard code requiring a dealer reset? Will it clear it self with time? Or likely a genuine fault? Battery voltage 12.58 with engine off. No obvious charging issues.

Answer 1

P1633 Keep alive power

There is only one dedicated fuse for this located in the engine fuse /r relay box listed as fuse 37 which is a 10 amp fuse replace if open, If the scan tool can not clear this code it should clear on its own .
