Battery replacement and PCM relearn - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I'm new to the forum. This has probably been covered, but I didn't successfully find an answer.
I purchased a 2011 from a warm State and had it shipped to MN. It's 14F out and the battery was original and barely started the car to get it off the transport. I replaced the battery but cannot drive the car until the snow goes away.
Will the PCM relearn or will I have to limp it to a dealer. Any advice on restoring PCM?
I have not started the car yet since I put the new battery in.
Thanks in advance for any advice.

PCM should be fine. Not sure about the newer gen cars, but for the older ones there is a bit of a battery disconnect/restart procedure. No big deal. It is outlined in the owner's manual. Check yours. If there is nothing written, it's probably good to go.

Thanks for your reply! The manual says to start the car, turn the wheels side to side, then drive it around. If the PCM light does not disappear, take it to the dealership. But we have a lot of snow/salt right now.
So I guess I was curious if anyone had any experience with this that they could offer.
