P03 - VCM communication error
P07 - MP communication error

first i would check the relays in the relay box and make sure they are ok. I've found that bad relays (EGI relays) can cause communication errors.
Also check the harness between the ecm and the meter panel, the com error is between the ecm and the meter panel, make sure the connectors are plugged in and locked in.
