History Codes E047 and B334

This combination of History Codes could be caused by:

^ Two opens in the Data Circuit isolating the ECM and at least one of the opens is momentary. One of the opens would be in CKT 800E, including the programmer and the other open would be in CKT 800A, 800B, the ALDL cover, or the BCM itself.
