Gen II Prius Individual Battery Module Replacement

its not that hard just stand the block of modules it on its end and remove them one by one

 

I purchased a used module, guy claims its out of 2007 or 09 prius and less than 100k miles, voltage was about 7.25 which could be fine if it was sitting ...--- well, i still have to find my phob but otherwise it looks like i might get rid of red triangle for a while and ill be using that ev button alot less as well - in place i have been driving a big suv v6 3L hog from , dumped 35 $ in it , would have prob spent maybe $10-17 with the prii over the last 2 weeks , and i have restricted my 'going out' alot to mostly essential driving ..

 

ahh yeah 7.25v it must have been sitting for 12 months or more, maybe closer to 2 years but it could still be fine you wont know until you charge /discharge.

what's the identification number on the module?

yea v6's are fun but I like to glide around in prius not caring about fuel which is about $1.30 per litre here at the moment or near $5 per US gallon

I still like getting my old V8 out occasionally but it uses 20-24L per 100k Lol

ocne you go hybrid u cant go back, i mean its a brain dead decision, engine cuts out when u decelerate and sit at the light,
and these days lights r very long, or the drive through , gas is a really outdated tech and we should be using it as little as possible because of its nasty byproducts of combustion ..

 

only true because I can re-build my own battery, if I had to shell out $$$$ for a new pack every 8-10 years I wouldn't own a hybrid personally, some people don't mind the battery expense others trade their car for a new car before the pack fails! some people even buy a failed car just so they can fix the pack for fun lol (that's me) each to their own

 

so , the module serial number -- can it be used to identify year and car type, i understand these modules are used in hybrid camry and lexus, perhaps with some variation in those bigger cars

Yup, see below

Not that I've heard, but it could be that the info is not in the public domain.

283h4A13018e = 28 March 2006

244gja07542b = 24 April 2005

hope this helps

 

don't be alarmed by this, I have found most of my 05 and 06 modules to be very strong I actually hoard modules with those dates lol

 

well i put the 'new'er module in and moved 1 other module to try and make a better pair match, but the 12v bat is weak, it never get to the starting the engine mode, and most of the time not even an error code just a dash 'problem' and red triangle. will try with a strong 12v and hope i get engine to start have not put cover on bat but shouldnt need to just to start it , yes disconnect has been reinstalled.

 

If by you mean that the car never gets to READY mode, then I do not think your 12 V battery is going to be the problem. If by "weak" you mean low 12 V, then you can eliminate that by giving it a charge to full, but as I said, it is not the 12 V battery that is stopping the car going into READY. Did you lock down the safety interconnect plug ( the big orange one) by sliding vertically down until it "clicks" into place as the last step?

You need to put your scanner on the car, clear all current codes at this point and rescan after attempting to start the car. Then post back here with the code(s) (if any) that come up. Otherwise we are all just guessing.

 

yes, i beleive i did lock down the disconnect plug sliding down vertically, not sure i heard the click though. i didi get a poca0 kind of code though .. saw the trianglde and the square main bat failure icon on the dash ... am charing 12v but alos will try newer fresh 12v sealed Lead acid bat ...

 

That doesn't seem to be a valid Prius code, did you mean P0ACx? If so, you need to focus on the Hybrid Battery Pack Current Sensor Circuit.

Usually this means there are Hybrid Battery Codes present. I suspect you battery needs to charged and top balanced (as a minimum) to get it to function without setting DTCs.

Good luck and keep us updated with your progress.

 

did you clear the original codes by disconnecting the 12v for a while

 

ok, what i handnt done was throw that disconnect the extra distance to get the 'snap' / click .. which was like slide down thing ...
after doing that hten inserting the phob in ign, it went to ready and started, with some vibrational and heavy lugging and shutterings ,,soc about 49 or so about 19 amps charge, the shuttering was pretty bad so i turned it off after about 20-30 seconds .. i didnt see any codes thrown but the triangle and 'problem' on the dash was there , maybe it will go away on the next couple of starts ...

 

I will discon the 12v for a few min to clear codes ...
