"Attached PCM's serial number is missing"

Went to start up my car and it would die with any throttle.

It was throwing MAF codes but haven't run a MAF in a year CLSD.

I attempted to upload the existing tune with no success. Serial number blank not detected. Screen prompted me to "Please perform a full reflash of this PCM."

Pulled PCM and discovered corrosion in the left blue connection. The other blue and both reds looked fine.

Is my PCM bad?

I wasn't tuning and hadn't logged or flashed in a week at the time of the incident.

Thanks for any help!

Can you get the corrosion cleaned up (you will have to open the PCM case and see if the pins have continuity to the inside)...?
