Hey guys,
I've got an LMM ECM here that I'm going to use as a "mailer" I pulled the tune off of it no problem, flashed it no problem..... it has a list of DTC's, And they won't clear, they just instantly pop back up.... i'm guessing it's because it's not able to communicate with the other sensors on the actual truck right? So if I dropped this into an LMM it'd work fine probably, but just want to confirm this. The codes are:
P2033
P0090
P0193
P0843
P0102
P2453
P0101
P0401

Thanks! :cheers:

Bench ECM's always set a bunch of codes, when it's put in a vehicle they will turn to stored codes but no longer current (no MIL).
