This is one intriguing/complicating system. "pl_silverado" looks to be posting the correct solution here. They say you *have* to replace the entire seat belt assembly, if that seat fired off its initiator gas cartridges. There's one in the seat belt pre-tensioner retractor section (at the base of the B pillar), an one in the seat buckle pre-tensioner assembly. So both sections of the belt(s) would be required to be replaced. Once the initiator has fired off, its loop resistance goes above or below the loop resistance value that the SDM must see. You *could* run a test of those seat belt buckle portions by disconnecting their 2 pin connectors. A good circuit would have a value between 1.2 an 5.5 ohms. If you were to jump the 2 pin connectors with a 3 ohm resistor, the SDM would then see a value indicating a good loop (an I'm sure would cancel those 2 fault codes you have). With the circuit reading about 3 ohms from both buckle portions, and your original SDM module installed, I suspect the system would test good. If your out getting 2 new buckle sections, you should end up with the same results as above.
added info. I see the buckle sections are still available for about $88 an up for each with P/N's 19205508 an 19205509
