The BT scan tool should probably be able to reset the battery condition monitor. I've just ordered mine and when I get it I will check the software to see if it does. Going to the dealer to replace the battery is expensive, and the BT scan tool at $280 for the enthusiast version should well cover the cost savings by DIY vs. the dealer install. I'm using it as an excuse to buy the BT Scan tool. (although I bought the pro version…)
Where did you get your scan tool from? Did it work?
