The couplers are fired directly from the R4LC on that model. First thing, check the wiring to the couplers and verify all is well. Next, I'd check and see if there's an issue with the pickup wiring to the motherboard. Although most of the locomotive functions will operate at around 11-12 VAC, the couplers require at least 15-16 VAC. If the MB is getting full voltage, I'd try swapping the R4LC. If it works in another locomotive, or a replacement works in this one, you'll need to replace it.
