Toyota Prius Engine Manual Rm1075u
Having just purchased a very high mileage used 2005 Prius for a good deal and putting about 1,000 miles on it before getting the triangle of death, I was faced with the thought of spending $3,500 for a dealer battery replacement or attempt to DIY for about $50. Thankfully #ryousideways just finished on a a great documented write up in a thread and a must read before you get started as I am just going to summarize my experience with pictures. My Error Codes: P0A60 - Voltage difference between battery blocks is higher than standard P3019 - BATTERY BLOCK 9 BECOMES WEAK 1st Lesson Learned - You can't trust the error code descriptions from any OBD2 reader, except at Toyota. Make sure to check them online against official Toyota repair manual descriptions. Hello All -I am in the middle of doing (almost) the exact same hybrid battery cell replacement as wegortw completed. After getting the TOD (triangle of death), my Toyota guy scanned my 2005 Prius (238K miles) to get me code: POAA6-INFO 526. I removed the battery and all connections and volt tested each cell.
All 28 were (almost) exactly 7.65. However, when I put the ohmmeter to each terminal, #12 gave me a reading of 4.32. I am assuming/hoping that #12 has an internal short to ground. I have ordered a $36 replacement cell from eBay that is tested and balanced at 7.6 volts. When the new #12 arrives, I plan to install it and reassemble the pack.
I plan to parallel connect the 28 positive terminals on one buss bar, and duplicate on the negative terminals. I plan to allow this 'leveling' to settle overnight (or longer). I will then remove the jumpers, and double-check the voltage of all 28 cells again. If they are all within a few hundredths of each other, I'll put the pack into the car, say a prayer, the hope for the best. I will post my results in a couple weeks, maybe by mid-July 2016.

I had to replace the Old Clockspring as you know, Many Prius's out there has a huge safety issue with the clocksprings. =Yes the Horn needs to be working not on Mute when you need to use it to avoid someone hitting you,especially the quiet Prius. Ofcourse the steering controls die.
I bought a new clockspring to find out the Grey-Plug connector is missing. I installed it without connecting the Grey plug- I tihnk it is for steering sensor. Now my car slows down and stops, VSC, check engine, Red triangle all lights up. I know it is for not connecting that Grey plug.Anyone installed a clockspring the new Part#, did you transfer the old plug-connector to the new assembly. Please let me know.

When I transferred the clockspring in my car (which also had an 'updated' stock number) I remember the steering sensor (behind the clockspring), and believe it is plugged in separately from the clockspring. I would take off the wheel and look for the plug in for the steering sensor. You may have to go to a dealer to recalibrate the steering, but I would look for the plug in for the sensor first.
I mentioned unhooking the 12 volt battery as a first attempt after finding the plug in to see if this calibrates, but then the 12 volt system should have been disconnected when working with air bag systems. Various warning about working around the air bags discouraged me from writing instructions about this in my original posting.

Hi Northwichita, world would be such a more beautiful place with nice people like you. Thanks for your feedback/support.
I have learnt an expensive mistake from all this. Never throw your old parts. Well who knew. I took it for granted my first replacement clockspring from ebay will be good and so did not want to have the clutter and threw the old(1st) clockspring with the steering-sensor attached to it. Well after I had to buy another clockspring(new), I was able to return the bad sensor back to ebay seller.I did that right after I installed the brand-new clockspring. My timming was so bad to realize the next day I should have kept it to least try to transfer the sensor. Steering sensor Thanks to you Northwichita, I bought that sensor you pointed out to me on ebay.
Gentleman said it is simple to detach and transfer onto the new clockspring. Well I did mention to Toyota service personal, however they just acted to listen seriously.
All they mentioned was the recall for the inverter-pump, which I ended up getting replaced by them. Chrysler has recalled half a million vehicles due to clockspring failure but not Toyota. They are just going to wait till someone dies to act I guess. Just like the run away lexus stories but finally openned their eyes when lawsuites popped up. I know so many prius people need to get this clockspring replaced free by Toyota, they should honour it free. Also the typical headlight syndrome, that sure is a safety hazzard. Why else would the police stop a normal vehicle,in their mind it is a safety issue.
Well I have to turn on and off when my HID lights act up, it is very intermittent. Check pm's Also, without the steering sensor, wouldn't you have non power steering?

Click to expand.I bought a used clockspring from a reputable salvage yard by mail order. It came with a piece of tape on it to prevent the top from rotating relative to the bottom of the clockspring - which I appreciate.
I straightened my car front tires and leveled the steering wheel when I installed the clockspring and removed the tape. I now wonder if the salvage yard centered the donor car's front tires before removing the clockspring. I called them today and they weren't sure. Searching this forum, I saw the above procedure - what exactly is in step #14?
Does it say how to 'center the clockspring' before you install it onto a car with the tires pointing forward? If installed wrong, I think the clockspring can be wound too tightly or loosely when you turn the steering wheel fully one way or the other. Click to expand.Your idea makes sense. My airbag light and CEL came on, so I checked the clockspring and found one ribbon was pulled out (broken, nonrepairable). I wondered if the clockspring had been installed (by me) wrongly. Before I removed it, with the tires pointed straight ahead and steering wheel level before I took it off, I counted clockspring revs each way until light pressure was felt. It was 1.75 turns to the left, and 2.75 turns to the right.
(Since you can only go full revs, my other choice would have been 2.75 turns left and 1.75 turns right, which is equally 'uncentered'). I think it was installed properly. Now, I don't know why the ribbon broke but it broke at the exact time I turned the steering wheel full lock right, to look at something behind the front right tire. Could it be the Prius steering wheel will break the clockspring if it's turned full lock?
That would suck. While driving normally, I noticed to make a 90-degree turn on a street corner usually only requires 1-1.5 turns of the steering wheel, far from FULL LOCK. I would sure like to hear from an expert on this subject. Does anyone know if there has been any progress on a recall on these spiral cables - clock springs? And, if not, where would I go to complain towards getting such a recall? Wonder if this is one of the parts affected by the earth quake/ tsunami. Mine is in the intermittent stage.

Mostly it is just affecting my Info button and both defrost buttons. I go down the road pressing these buttons, over and over again, till they go to working. But soon they stop again.
Have noticed that turning the wheel seems to help make them work again. So it must be this clock spring/ spiral cable. Does anyone know how much the Dealership will charge? I got to know from my dealer it cost around $500 for a fix and they offered 15% discount because I complained is recall COT none aligned steering wheel issue pointed out in another thread. I have mine damaged upon the latest recall for Steering Shaft change Prius Second Generation. I filled complain to NHTSA as well for the faulty cables.
Toyota customer relationship been notified too. If you do come to have this issue after some work done from the dealer I advice you to find out if they have something to do with as many dealers mechanics are not aware about the procedure to realign the steering wheel to the center.
For my case the info button, recirculating air button, and the rear and front defroster buttons were affected and they do work fine if I twist the steering wheel to the end left.

Click to expand. Hi rufa33, So looks like you've just been living with the issue for the time being?
I'm going to try to find time to go to the dealership (where is had the recall work done) and see if I can get lucky. I've been lucky in the fact that things seem to be working fine since I went for the recall (February 15, 2013). About 1 months ago I noticed the INFO button started to not work but just within the last 2 weeks, all the ones you're having problems with are faulting. The buttons tend to work if I turn the wheel and press them (like everyone else) but I doubt it's a smart thing to do when going 70mph on the freeway.
If you hear anything from all the organizations you have written to, please keep me informed if you can.
