You'll need to rewrite the immobilizer code with the ECM/PCM replacement procedure in the HDS. The VIN will also need to be programmed into the ECM, or DTC P0630 ''VIN Not Programmed or Mismatch'' may be stored because the VIN has not been programmed.
I believe this can only be done at an Acura dealership, but I'm not 100% certain.
