    Hi All.

    I just recently purchased a 2008 model with some what seems to be small accident damage, bonnet, front & rear passanger lights & slightly sagging bumpers.

    It's due to be delivered in a few days from interstate where someone else checked it out for me (sigh), where I will be able to assess it myself.

    I beleive it's has been moved around the yard, but I'm guessing there may or may not be other damage...but wondering whether Toyota service would have to [reset] it or anything else for that matter even though the air bags were deployed...???

    I'd say the batteries would be run down and need a full charge, which I ask whether I could put mains volts or a battery charger to it somehow given I wont be driving it for some month....

    I found a US company that sells really cheap parts which is a reall shame given I'm in Australia, namely a bonnet for under $100 US, where a new retail price I got over the phone was $700 AU which didnt take much to bring that down $480 AU.. so wondered if that's site price was about right. (carpartswholesale)

    Also how would I get into diagnostic mode with this model, and I'm a bit of a IT head and would be interested to see more of the backend operations.

    Anything else I should consider when I get the car would be much appreciated, like disconnecting the battery & having to reneter the radio code...

    Cheers
    Tekmann :)

    Since the airbags deployed, the SRS ECU will need to be replaced.

    The original equipment hood is aluminum, and this is why it is more expensive than an aftermarket part, assuming the latter is made of steel. I know one US poster who was dissatisfied with the fit of the steel aftermarket hood and bought the correct aluminum hood instead.

    I recommend that you obtain the repair manual for your model year, which you may be able to obtain here: Toyota Service Information

    (I believe the comparable US website does not accept orders from outside North America.)

    To obtain DTC codes you will need an OBD-II code reader that is compliant with Toyota CAN, and this still may not pick up all DTC logged by the various ECUs.

    You can recharge the 12V battery using a regular battery charger, I suggest you observe the warning label that indicates no more than 4A charging current.

    It's not really a DIY project to charge the traction battery unless you know what you are doing... Good luck.

    There is no radio security code to worry about.

    OPPS... That was a typo in my orig post as the airbags [wern't] deployed, as sure they would have cost a small fortune.

    Just thought there may need to be other stuff reset from toyota.

    Thanks for the toy man link and yes that would be a good idea for a car like this. Would the manuals be in pdf or something so they can be downloaded..???

    So is there a reasonable priced odbII device I could use that is good all round for dtc & restting things from a notebook that people have experienced.

    Can you add an additional Traction battery pack that would be acknowledged by the computers as being there or is that cost prohibitive.

    Also I read somewhere they are or have put a mains outlet/inlet on the new model so charging from the house could be attached...and wondered if anyone has installed a charger for the traction batteries on older models.

    Thanks

    A simple OBDII (in the US model at least) is all you need to reset the codes. Just leaving the 12V battery unhooked will do it too. PDF manuals are available. When I repaired my '08 the first thing I did was to unhook the traction battery and I left it that way until I had the drivetrain completely repaired and ready to test. Chances are that you battery will be OK even if it has been just used to move the car around the yard.

    Bump...

    Hoping to get some responses from my previous questions, before this thread falls into deep space...

    It's Here. NeeD HELP PleasE

    I received the 08 Prius today, only to find the aux battery was flat so I jumpered it as per manual and ICE started and dash lit up.

    The tractionHV batteries were showing 2 bars on the screen, and wouldnt go into EV mode at that level.

    The ICE ran smooth at first then rough and seemed very irregular, so intereted to hear what that was about, and assuming because it's been sitting around and maybe jumped started before.

    There are many things I dont understand yet, but reading through the forum as much as possible with great interest.

    I tried to move the vehicle forward selecting the "D" position with the parking brake off and foot off the main brake, but it only crept 3-4meters forward, and reverse was only inches while it was in reverse beeping away.

    I dont understand what goes on there, but do observe there are faults lights on, namely the red trianglur & double round circle with exclaimation in yellow is on, also the multi information display lcd has a car with exclaimation through it..

    I had the aux battery disconnected while recharging for few hours, and just reconnected to find none of these errors we cleared...???

    Suprisingly this accident was only very minor visually, so astonished it's got these issues.????

    Thanks in Anticipation

    Based upon the warning lights, you have a problem with the hybrid vehicle system and a problem with the braking system. I recommend you have the car towed to your local Toyota dealer so that the diagnostic codes can be retrieved.

    Or, you may wish to buy this tool for US$400 (incl. the Toyota enhanced option) to run on your laptop: AutoEnginuity® - OBD2 Scan Tool - Professional PC and PDA Diagnostics

    Thanks for your response Patrick.

    Do you know if the odb2 scan tool read & reset the same codes toyota can read or will it be limited in functionality.

    Could this be why the vehicle is moving forward only a few meters, as it does seem like the brakes are on, as the engine labours (knocking/pinging usually when older car towing uphill) which I found in the first few seconds, hence pushed it thereafter..

    Edit: actually maybe not as although the car labours to go up the driveway, it freely rolls back down the driveway.

    Could there be mechanical damage..or worse still ECU computer damage???

    The Autoenginuity tool is supposed to provide similar functionality as the Toyota diagnostic laptop regarding reading the DTC. A generic OBD-II code reader probably will not read the codes that your car has logged, as it is likely the skid control and hybrid vehicle ECUs have logged codes.

    You mentioned that your engine idle is rough and that you are having trouble moving the car. Without pictures it is hard to say whether your powertrain suffered mechanical damage.

    I recommend that you inspect the car very carefully for such damage and also look for damage to the wiring harness and the wiring harness connectors. Any visible damage should be repaired.

    The accident damage seems minimul but I will inspect further when daylight breaks (6.30am atm) and I can attach pics of where it was hit, as soon as I find out how...???

    These really dont show much as most of the damage seemed to have occured to left front corner (US drivers side, our passager side)

    Edit: As these pics show one (me) wouldnt think there would be powertrain damage, but will try to get it up on a hoist soon and inspect further, though not sure which pics to take atm.

    Is the rough idle something to do with engine calibrating itself, and what codes are reset when aux 12v battery is disconnected given I did that.

    If you can get the hood open, let's see what damage (if any) was caused to the transaxle or other parts.

    You might be right regarding the rough idle. Let's find out what DTC exist.

    The bonnet opens fine & the front raidator support & inner guard needs metal work if not replaced, but there are no visual signs of damage to the wiring loom or engine components (transaxle) that I can see, though getting it up on a hoist once movable may reveal more.

    I'm assuming the transaxle is the gearbox hookup to both of the motors, which hasnt been touched that i can see.

    At a guess the loss of water from the radiator (not presurised atm) & the tank next to the electric more may be part if not all of the reasons why the errors appear not detecting water.

    I would like to also put charge in the traction batteries, to see if that will move the car, as opposed to the ICE...but need to know how to charge them manually as cant see running the ICE atm.

    Is there any other way to view the DTC data from the lcd panel, apart from the scantools...???

    The MFD will not display DTC.

    I recommend that you do not try to start the engine anymore, until you've identified and resolved the car's problems. Maybe you won't have to worry about charging the traction battery if you don't deplete it further.

    It's not easy to charge that battery. One approach is to charge one module at a time; however the traction battery ECU will log a DTC if it detects that a module is undercharged compared to the other 27.

    Another approach is to charge the entire battery by applying ~220-230VDC. However you'll need a variable voltage source so that you can adjust charging current. You also need to carefully monitor module temperature and charging current or you could end up with a disaster as the modules may explode.

    One of your previous msgs indicated the traction battery SOC gauge is at two bars. That is around 45%-50% SOC. Therefore, the battery doesn't need charging at this time.

    If you wanted to charge the battery anyway, then if you maintain 0.5A charging current I'd suggest that you stop after 3 hours, which would result in 1.5 Ah into the battery. The capacity is 6.5 Ah when new.

    The idea is not to fully charge the battery, but rather to put enough charge in to start the Prius. As you approach full charge, you run an increasing risk of damaging the battery.

    There are aftermarket aluminum hoods, they cost about 50% more then the steel, still much less then factory.

    Without the DTC nobody is going to be able to do more than speculate on what is wrong. If the cooling system is empty I would not start it or try and drive it though.
