ECM Y
p0132. FRONT OXYGYN SENSOR HIGH/ENGINE RICH

0n001439-01 probably a part number

BCM Y
62116 THIS IS B2116 fuel pump output open
62271 THIS IS B2271 BCM VOLTAGE LOW

SPD0 Y...not sure if the D is a D is way a funny character
u0100 LOST COMM WITH ECM

Also this showed up somewhere pn41000351a this is just a part number

I would pull the connector off the ECM and make sure it's all clean. Put some Dielectric grease on the contacts and plug it back in. Clear all your codes and start it up and see if they come back

There is likely nothing wrong with your BCM. It is the module that generated the DTC's, and it's doing it job. Replacing the BCM would likely accomplish nothing, other than lightening your wallet. It's difficult to diagnose DTC's over the internet, without knowing the specific details (what work was recently done) that may have triggered the DTC's.

But one of his codes were he lost communication with the ECM. That's why he should unplug it, make sure there's no corrosion and put some Dielectric grease on it and plug it back in clear the codes.
Losing communication with the ECM could have caused the other codes.

There's 10000000+ YouTube vids, 100000 pertain to shade tree mechanics, take your pick.

Once you remove the ECM and clean the contacts and reinstall, clear the trouble codes.
