alternator question

I'm getting the following DTC codes for the alternator:

[] P0621 - Generator L-Terminal Circuit (Pending) (History) (Current) (Immature)
[] P0622 - Generator F-Terminal Circuit (Old) (History) (Current) (Immature)


Ok, here's my setup: I have a speartech harness that has a 2 wires plug going into the alternator (red and grey). The alternator is a 2004 Silverado 145 amp alternator (internally regulated). Since it's internally regulated, can I turn these codes off? TIA
