Need help with codes after installing an unlocked pcm

[Harold61]

I sent my PCM to get unlocked to diablo sports I have a 2016 ram 1500 rebel edition 5.7 liter engine once I installed the unlocked pcm the truck threw so many codes if the clamps on the PCM is not down right could this call mupitable codes

Yes, what codes are you getting? Poor electrical connections can cause all sorts of craziness, especially pcm.

Clean the connector at the harness end and the PCM end with electrical cleaner.

A loose, dirty or corroded connection will cause multiple codes.

I just swapped my PCM for an unlocked diablo last week, went flawlessly.

Try the stock PCM and see if the errors go away?
