Thanks Josiah, I had the exact same problem on a 2008 Toyota Highlander hybrid. The drain plug in the hybrid battery compartment was completely clogged and I had about 2" of water inside after a big storm. I trimmed off the bottom of the rubber drain plug to make sure it drains. Also drilled a new hole in the front. Your corrosion was a lot worse than mine.

Going into this now...same code on an 06 highlander...EXCELLENT JOB !!! WELL DONE!!!

FANTASTIC! This is just what I needed to see. Am trying to find the cause of an isolation fault in a 2008 Lexus RX400H and we found water in the trunk. Not sure that I'll try this myself though, bit worried about getting zapped by the battery voltage, but at least I now know what to look for.. Such a bad design by Toyota / Lexus, how can they get away with this? Thanks again, very good video. Will look at your other on on how to remove the batter itself. Wish you all the best 🙏

Very nice video. Thanks you for sharing
