62 EMR Miles Not Stored (Unsuccessful attempt to update the EMR (Emissions Maintenance Required) mileage in the PCM)

Had the battery disconnected for a while. I have never seen this before. I did manage to forget to put two plug wires back before I started it then put them back on the wrong plugs. It ran in both cases! Anyway took off like a rocket when I got them back on the right plugs.
So what might causes this? Is there anything I should do? Its a reman PCM 7-20-21

 

How long was the warranty on it? If it was a year, I would give 'em a shout, and see what they have to say. I have never seen that one before.

 

I pulled the neg battery cable for 20 minutes and started it. The codes are 12 and 55 now. I'll keep an eye on it. I think my screwing up the plug wires had something to do with the new code.

 

I think you’re right 94.
