This 2008-2013 Toyota Highlander Hybrid will not start. Has code AA006. This video will show how to save money repairing this issue and not just replacing the battery pack or the battery cells. I am not sure if the Prius has the same battery system or issue. This video shows how I am doing it and is not necessary a how to.

Thanks for documenting these issues & your efforts with safety measures, appears you fixed the cause of the DTC & provided some prevention recommendations, but unsure where applied except the suspect cargo door seal along with a clogged drain filter. Definitely possible areas requiring constant attention in high precipitation areas & conditions where debris accumulates. In my experience, Lexus hybrid has high integrity from intrusion & seals sometimes feels like a vacuum when opening the door. Then again, Imma motivated to access the battery area for look see, should be easier without the third row seats like your rig. Roll on brother,😁

First and foremost. Thank you so much for this video. Here are a few things I had to go thru with mine that had this problem. With mine as a dead give away symptom is at night when it cools down the inside of the windows would fog, get condensation on them (I dismissed this at first. Hindsight aye?). Also if you have a hydrometer you can put it in the car with the doors and windows closed, if it reads a lot (5%+) higher than when its outside chances are you have water collecting somewhere in the vehicle. Mine also had the same start ignition symptoms, But when I scanned for codes no codes were returning. Most people diagnose this as a vacuum leak which is common (gas cap, evap system broken hose etc), I had to get a better reader that could scan the hybrid management computer, not every scanner can do that. I used an ELM 327 WiFi adapter and EOBD-facil software on my iphone to pull the code of P0AA6, the free version of the software can pull the code. My Vehicle is a 2006 Highlander Hybrid.

The tubes you were not sure of are the Sun Roof drainage assembly. That is the most common problem with these cars. The seals leak, the hoses clog with debri and tree snot. This will cause water to leak all over the inside of the car behind the interior plastics where you cant see it happening. Thank You for making this video

After some research I see these were sunroof drains. They were not the problem with this particular vehicle though. It turned out to be the tail light seals. There will be a video soon. It was a nightmare finding the leak.

I just googled it. I do not have the diagram. If you're getting power to the orange cables, it will be on the battery side. Most likely the relay area in the battery. If you're not getting power to the orange cables, that is when you would need a wiring diagram.

I just had the very same thing (same codes, warning lights and everything) happen to my 2008 Highlander Hybrid. A few days ago we had two days of rain with about 4-6" of rain and this was the first time using the car since the rain. I checked for water and sure enough everything was soaking wet. I will tear into it in a few days because tomorrow is another full day of deluge. I think I will put a tarp over the car for the rain. Same thing happened to me last year at the exact same time of year after a bunch of huge rain storms. I took about a month and replaced the timing belt, ignition coils, spark plugs, water pump, cam gaskets, crank gasket, and tensioner and when I got done it started right up and no codes. Looks like the hot and dry weather for that month might have dried out the water last year. I was grasping at straws trying to fix it last year and refused to replace the synergy drive. The car is only worth about $3k now after my rear door got smashed in by an 18 wheeler in a snow storm last winter. I have 240K miles on mine so those other things needed changing anyways. I will keep you informed on my progress. I was ready to call the junk yard to come pick it up.

So there is some relays in inside the battery pack. It's where the orange wires connect. If you cannot clean the corrosion out of that, you will need to replace it. I just had to do it, I will be putting the video out soon. I found the brake lights housing were letting water in, and then it would roll forward.

Thanks for the heads up. I'm sure I will find the battery compartment full of water and the drain clogged. It was almost identical this time like it was last year. Didn't get 1/2 mile down the road and right after a rain storm.

@@CousinCleatus Cleatus, Sure enough, I had about 2" of water filling up the battery pack compartment. The water was almost touching the two main hot wire. The compartment was already rusted. I live on a 1 mile long dirt road with hills and that was why it would short out and trigger the relay and the codes so close to home. The main rubber drain in the battery compartment is a bad design and easily clogged. I snipped off the bottom part of the drain plug to make sure it drains easy now and does not clog up again. The drain is between the catalytic converter and the gas tank. You can actually stick a screwdriver from underneath into the rubber drain and see if the compartment is full of water before you tear into it. I dried it out with towels and I have fans blowing inside the vehicle now trying to dry everything out before I put it all back together. It was not as hard as I though it might be but you do have to be very careful with those high voltage batteries. I checked the connections on all of the battery relays and no corrosion. The water was just below that level. I will post again when I'm done. Pretty sure this will fix it unless there was some permanent damage done. I stopped the car right away.

All good. Works perfectly. I drilled a few extra holes to help drain in the low spots. No corrosion. You definitely want to remove that relay panel to Inspect it. I saw other videos with the same problem and the relay panels were in bad shape. Thanks again for the video.

I saw this problem on the facebook Highlander group - there's some kind of what look like body plugs or something around the tailgate on the lower side, somehow these rubber plugs fall out and then water goes into the car making it to the 2nd passenger row usually.

07 highlander hybrid(421000miles ) gave poa78 code and mechanic said the inverter(very expensive) may need to be replaced but later i found another youtube video which says it may be the grounding cable coming out the inverter that doesn't let it work properly. I checked it out it was rusted and cleaned the connection part of grounding cable by sanding them. I erased the code and made 300 miles the code has gone i even gained 0.1 mpg after this fix, let's see if the problem is really gone?
