Ok you can kinda see it. You said you believe the footing is above grade. If that is the case then you can do two things.

First (regardless of whether or not your going to reside the entire house) you can remove just the lower planks across the bottom few runs and flash it off properly using galvanized flashing material (can pick it up in rolls ranging in 4" to 12"+ height having a length anywhere from 25' to 100'+). Just slide the flashing up under the vapor barrier and nail/screw it off leaving a few inches to hang down past the footing. I also like to dab some caulking over the nails/screws to help seal it up. Replace your bottom rows.

Even if the existing siding terminates on top of the footing wall you can bend the angle to fit properly over the footing and down the side thus eliminating any moisture from coming in. Side note try no to put a 90 degree angle in a bend if the footing extends past the siding. Leave a slight angle to allow water to fall off properly.

Second you might consider a french drain around that area to quickly alleviate water from forming and flooding up behind the flashing, depending on the overall height of the footing wall.

Last thing is once the flashing is in place take some expandable polyurethane foam and shoot a little (key word "little") to help seal up any air gaps. You just don't want to push the flashing away from the side of the house.

Good luck and I hope this hasn't been too confusing & that it actually meets some of your needs.
