It's free to try, so the price is right. Remove both cables from the battery, touch the cables together...just follow the instructions.
See if it still does what you're describing right after you reset the ECU. I'm curious.

The battery is not involved in this procedure. Remove both cables from battery, touch cables together. Do not let them contact battery terminals.
Anytime you disconnect a car battery, remove negative first. When reconnecting, install negative last. This will prevent accidental shorts.

Do not bridge the battery posts/terminals, at all. EVER. That is a short, and the battery could explode. Hydrogen gas and sulphuric acid. Nasty combination.
I once accidentally bridged both sides of the battery when i dropped a wrench. A couple sparks, a little smoke. Thankfully, luckily, the wrench fell to the ground right away. Nothing blew up, and the cables were not connected so harm done. Except to the wrench. There is a burr where it got singed.
If you are going to disconnect either cable, cover the post with something non-conductive, just in case. I forget where i got them, but i use two rubber vacuum caps that fit over the posts.
