These folks http://www.dieselcontrolservice.com/inde...placement/ say 53 is Nonvolatile memory failure or Nonvolatile memory data is incorrect. Sometimes caused by oil inside the case shorting the memory pins but I wouldn't think that would be the issue with a new unit. Did they flash the new unit with the correct parameters?
Others say if the EEPROM was not properly flashed/did not take the flash, you can get that code. "Flash Code 53 indicates that the ECM was unable to read a valid copy of an engine data record (calibration, faults, or accumulators) stored in nonvolatile memory.Flash Code 53 also indicates that the ECM was unable to update an engine data record (calibration, faults, or accumulators) stored in nonvolatile memory."
