Assuming all earths and body grounds are all intact and 12v battery good etc etc.
ECM P0560 VBU voltage problem.
The ECM has a couple of internal 12V dc-dc 5v converters.
The one powered by the VBU line (responsible for backup data storage etc) should be live at all times.
Find the VBU pin on the ECM connectors and check that it has 12V power at all times.
If no power, then that's the problem.. (Blown fuse, bad harness etc)
If 12V then
probably an internal ECM issue. (Try another ECM)
MCM P1440 - 57
An unusual code and it may be a problem with the phase current sensors inside the MDM causing false reporting,
or an actual problem as described in the advanced diagnostics.
Assuming all the connections in the IMA compartment are secure/intact etc and it's not rodents, bad connections etc
1) Have you swapped the original MCM back in? Y/N does the code go/stay away..
2) The simplest way to kill all the rest of birds with one shot will be to swap out the MDM
the big silver box on the left hand side of the IPU compartment with a known good one. There are loads in junkyards over there.
If the same code still recurs then it may be an actual IMA motor problem but I would say that is incredibly unlikely.
