The battery on my 08 TL died twice overnight this week. I was about to buy a new battery when I stumbled across this wonderful site, and connected the dots that the HFL is stuck in "booting up" mode. I removed the HFL (and plan to just leave it out) but I still see the "booting up" message on the dash screen when I toggle to HFL. I just wanted to see if this was normal or if I somehow botched it? Thanks so much!

 

You will still see it since it is not connected.
