Default ABS killing my battery

So after weeks of wondering why my battery would be almost dead after sitting for 3-4 days, I bought a circuit tester and went thru every fuse. The ABS fuse under the hood has a constant .5 amp draw. I suppose I could just pull the fuse every time that I'm not going to drive it for a few days, but I would rather fix it. No fault codes from my amigo reader, no 3 amigos, ABS works fine. I'm thinking it's a relay. When I put the fuse back in, I can hear a click coming from somewhere inside the dash. After looking at the Rave, the only relay I can find is the ABS return pump relay. I'm wondering if the relay is stuck or if there's a sensor gone bad. (although I would think that would show up on the amigo reader ) Anyone else had this issue? As long as I drive it every couple days, the battery will keep a charge, but you only drain a battery so many times and then it's junk.

Eric

There is supposed to be a tsb for this but requires a trip to the dealer

Sorry, I forgot to mention I had that done. Dealer re-programmed the SLABS. That "faint alarm noise" issue coming from the ABS has been taken care of. I'm thinking either a relay or my ABS unit has seen better days. After 185kmi, it wouldn't surprise me.
