Ok, situation is more complex than originally thought. Let me see if I can summarize this short and to the point.
My car has the accessory package rear parking sensors, these were installed after the car was manufacturered, at the dealership when it was brand new.
This rear parking sensor kit package is different than if the rear parking sensors were installed during manufacturing. If they were installed during manufacturing the module would be in a different place, and the wiring would span the length of the car, and the TSB would apply to this type of installation for the fix where they have to track down the wiring interference.
However, because I have the accessory package installed after manufacturing the package is installed differently. The module and wiring is all in the back. Because of this style of installation the likely cause of the problem is a faulty module. This accesory package does have a warranty period, but mine is already past warranty, it's shorter warranty than the car because it's an accessory part.
With this accessory package you cannot just buy specific components, you have to purchase the entire accessory package and re-install it all. That means $600 for me to purchase it, and then have the new stuff replace the old stuff. There just isn't any other option.
So, we decided to just leave it all alone as is. While we could have had it disconnected we were worried the rear cross traffic alert would also then be disabled since it uses the same sensors, which work fine, the sensors are fine, it's just the module. That feature of the car works just fine, so I didn't want to deactivate it and lose it. Therefore, we decided to just leave it all as is. The beeping only happens in reverse, and all it means is my rear parking sensors won't work right, but the rear cross traffic alert still will.
In summary, the problem can be fixed, but it will cost me over $600 to do so therefore I opted to leave it alone for now. If I ever have extra cash in the future I can have the module replace. Right now, it just isn't that big of a deal, and it does not annoy me in any way. It's not like I drive the car in reverse. So not a big deal really, and the option is there in the future if I ever want to fix it if I have extra cash I want to burn.
Cliff Notes:
Because it's an accessory package the rear parking sensors are installed in a different way, and to fix the issue requires buying a new accessory package so the module can be replaced, which would cost a lot of money cause the parts are out of warranty at this time. I decided to leave it alone for now.
