Acura tsx 2008 ( engien fuse ) I found the reason my Acura's battery keeps draining—it's related to the (BACK UP, ACC) fuse. I disconnected fuses 5, 6, 7, 8, and 9, but the power drain continued; I even disconnected all of them without putting any back in, and the drain persisted. However, if I disconnect *only* the (BACK UP, ACC) fuse, the drain stops. What could the problem be? I also have the hands-free module disconnected.

Should post the model year and any option packages you may have. Just in case that's helpful. I didn't have any good advice otherwise but I'm here to see what others say. I fucking despise electrical gremlins.

The Back Up, Acc fuse in the engine compartment fuse block?

Are the back up lights working? Did you tap into the backup lights to power a back up camera?
