Right so it turns out that after giving another round of fan drying (this time a more powerful fan) the issue is gone for now (finger crossed). Gonna keep the fans on for 2 more days to be perfectly sure. Next up it to find the darn leak, think it is the rear hatch.

I can get it started once i remove 12v battery lead and connect again but I dont have anywhere to make a sharp downward nose angle to park :(, thus thinking to jack up, but also thinking to spend on getting those 1000v rated gloves and insulated sockets and just remove the hybrid battery and clean it properly.

Right so if ill get 2 x car jacks and lift it as high as possible that might be wort a try before going for battery removal ?

Unfortunately the warning is still there. Next thing it seems is to remove the battery and see any water underneath as fan drying probably didnt reach those areas. Would be seeking a local electrician to help out. I have seen the step by step process to remove the battery but would prefer someone with electrical experience to do it.

100% same issue ive got. Its the PA006 526/612. But i have removed the back seats and have 2 x fans + 1 x dehumidifier on. Going to keep it for 2-3 days. Wana be absolutely sure. Have removed the Hybrid Batter or its cover (dont really want to). Hopefully fans will do the job.

Hi All. Sorry didnt write before. So here is the situation. Techstream software and Cable ordered online for £20. Took many attempts but finally got it to work. Anyone needs help in installation of the software then let me know. Now the sad part, the error code is P0AA6 "Hybrid Battery Isolation Failure". I have checked this forum and there is videos on youtube and seems its been caused by water ingress. Now I admit that front passenger side beam where the air bag is has wet mark and suspect that a leak from there has caused the floor wet so much so that its wet all the way on back side floor too. I hope drying it up and then trying again would sort it, but to dry it would be a mission in itself (any ideas welcome). Hopefully the water hasnt made its way to hybrid battery because that would mean removal of back seats to access. If that's needed to be done then ill be sending it to a garage as im really bad with electricals.

Hi. New to this forum. Lexus RX-400h 2007 101000 miles. Issue: Starter 12v battery drain, every winter the issue comes. This time when replaced it with new Bosch battery and after 2 min of driving the Check Hybrid, Check VSC message started showing and the caution lights of car slipping and power check comes on as well. I thought it maybe the new battery isnt the correct one so replaced it with another new battery but same thing is happening. The car wouldn't start and only way to get it start is to remove the 12V battery terminal and plug again but all lights would come back again after 1 min. Have ordered the techstream and now waiting. But any suggestions are welcomed.
