Default EPS module replacement

Hey guys, not sure if this is in the right section but anyways..

I'm in the process of trying to diagnose a suspected EPS issue and was just wondering what the differences between all the part numbers were?

My car has an 39980-S2A-A03 (00' AP1) module, while I've seen on ebay some have, 39980-S2A-A01, 39980-S2A-A02, and 39980-S2A-A04.

Are these all interchangeable?

Thanks in advanced for your help.

According to a Honda part search, the following eps control units are interchangeable for 2004-2009 US Base AP2 models: 39980-S2A-A05, 39980-S2A-A03, 39980-S2A-A04. Furthermore, for the 2000-2003 US AP1 models: 39980-S2A-A02 and 39980-S2A-A01 are interchangeable. It is interesting that you have an 00' AP1 with an AP2 specified control unit. I know that for North American models, the steering rack gear ratio changed from AP1 to AP2 which might be part of the reason why the eps control units changed.
