Hey John & Guys, My 2005 LS 430 is having similar battery charge drainage problem. The AFS light is flashing so the thought is that perhaps this malfunction is shorting the electrical system . The dealer says drainage & AFS probably not related. Dealer also said that AFS no longer available in their inventory, car too old. In Covid situation, I’m not driving as often . Dealer says that’s probably problem. I’ve pulled the AFS fuse, light still flashing. I haven’t noticed any interior lights as cause. Stumped as to next step to solving battery problem. Any ideas ? Thanks, Paul

Hey Dave (?) Thanks for your response to my AFS issue. A concern of the flashing AFS is the unusual battery charge draining at the same time. Since there has been no reports (from dealership or Lexus Club members) of a direct correlation, such as the AFS unit causing a short circuit, I’ll investigate other possibilities of battery discharge. Thanks again for posting the tutorials, they are very helpful. Sincerely, Madiro

Lexus Toyota Dealer said AFS system on my 2005 Lexus LS 430 is no longer available. Is there anyway to disconnect AFS and still have headlights? My battery (new ,month old) is draining while sitting after 3-4 days. Seems to be related to AFS system malfunction. Any suggestions? thanks,
