I have had the red triange after having the car parked in extreme rain/heat pop up when I start the vehicle 3 times in about 6 months. The first 3 times I did not have Techstream so I just cleared the codes, but the third time I finally read it and had those 3 codes, the first two I assume being most important. I clear the codes each time I see them and they stay off 1-2 months. About 140k miles on car. New 12V battery. No driveability issues. Car still gets decent 60 mpg in summer, 50 in winter.
I'd work on the p3009: High Voltage Leak Detected, internal to battery Often this can be because of internal corrosion of the High Voltage battery. Are you up for the challenge of opening up the high voltage pack? If so, after checking the internals of the pack I would either clean or replace the harness.
Just wondering, but if I do decide to do it, what tools and parts do I need and what procedures must I perform? What do you guys think of those Dorman 587-000 Reman Hybrid Drive Battery that are sold on eBay with a 3-year limited warranty? I figure if I ever to take the thing apart, I may as well install a remanufactured battery. At $1,500 it's not THAT much money. How much is a reasonable price for a mechanic to charge to replace it? I figure 2 hours should be enough.
You should not take it apart if you do not have proper safety equipment or knowledge. I was thinking you had done this before. Sorry. A mechanic could do it in 2 hours. There could be an upcharge for bringing in your own part, plus this requires safety equipment that they don't usually have on hand if they have not done it before. ie high voltage gloves, etc.
seems a bit high, i would shop around. what is he going to use for a battery? if it's the 1500. doorman, it shouldn't be more than 2k total.
I could sell a refurbished pack to you and help walk you or your mechanic through the process. It won't be as low as $1,563, but it won't be $2,000 either. Feel free to call or email me when you have time.
Thanks. I'll see if the car gets worse. Otherwise, if it works and gets good fuel economy, I'm okay with it.
I've got two 2002 Prii, and each went down with a P3009 error. On car has 183,300 miles on it and the other 128,000 miles. Last week I decided to start taking the first one apart to tackle the corrosion problem. Here's a brief description, minus a few steps. After getting all the seats out and the trunk rugs out I could finally view the battery. I pulled the safety plug and then I could start on the battery. After removing all the screws that held it to the floor, and the wiring harnesses I slipped two 8' 2X4's into the trunk and pulled the battery out on to them. Then I pulled the battery up the lumber and out the trunk. It's much less awkward than pulling the battery out the side doors. Then I lowered the battery down onto a small dolly and started to take the shroud bolts off and remove the shroud. After this I took off the busbars and removed the copper bars within the plastic frames. I removed the sealant from them and burnished them down with sandpaper. After the plastic and copper bars were clean I reassembled the busbars. After re-assembling the battery shroud I pulled the battery back up the 2X4's and into place in the car. I installed one screw to ground the case, installed the electrical plugs and the battery safety plug. Then I reattached the ground cable to the aux battery and started the car. No more errors. Yesterday I started the 2nd Prius. I'm ready to reinstall the traction battery in the morning. The first Prius was a learning curve. I figured it took about 1 hour to get ready to pull the battery out. 15 minutes to safely pull it out by myself. Each busbar took about 3 hours to clean. The battery itself took about 20 minutes per side using G00-off to remove the excess sealant and corrosion. Reinstall took another 15 minutes and about 2 hours to button everything back up. I can easily repeat this over a week-end. Tools: 3/8" ratchet and extension 1/4" ratchet and extension 12 mm sockets to fit both ratchets 8mm sockets 14mm sockets Plastic Panel tool Small flat bladed screwdriver dental pick, one end straightened Goo-off remover Sandpaper 100+ grit needle nose pliers Utility knife 2 small bottles of petroleum jelly (Vaseline), this is used to pack the front and back of the busbar cavities when reinstalling. It helps seal the copper and keep down the corrosion. That's about it. If you want more information just email me at [email protected]
Please. check back periodically (every 6 months?) to keep us up to date on the longevity of your cleaning for keeping the error codes off. Thanks.
Nicely done! IIRC Toyota had a recall on Gen1 Prius to correct corrosion problems inside the battery case. Was this recall performed on your cars ?
I think so, both batteries had hand written notation with dates of 2009 and 2012. I'd have to run it by Toyota to find out for sure.
