Does the turtle ever go away after the cars been running for a while?
If its coming up with the "FAULT" light on the charger it means you likely have some bad cells in your pack. Image
As far as I know the toyota dealers dont want anything to do with the Jap import Prius's at all!
There is still the possibility to revive the car.
Your options as I see it are:
Get a complete reconditioned pack

Replace only the bad strings and reassemble
This will involve working with high voltages. Even with the service plug removed there is still over 144V once you open the pack up.

Keep trying to use the inbuilt charger until you get enough charge to start the ICE.


Also I suggest you join up on this forum that is dedicated to the MK1 Prius with people that know alot more about how to keep these old Prius on the road.

You could also contact the guys at the EV Shop. They do hybrid servicing and repairs.

If you are thinking of selling it to the wreckers I would very much like to buy the transaxle (or possibly the whole car) for more than the wreckers would give you.

You will need to replace some faulty cells or sticks of cells (they come assembled into tubes) with either new cells or reconditioned cells. Someone like Mr. Mik (search these forums) might be able to provide you with some reconditioned cells at a reasonable price.
It seems that the TOYOTA dealer here have no experienced mechanic to fix my car.
As noted, these imports are not touched by Toyota Australia. Well, they might take your money and change the oil for you, but they won't be able to help with anything specific with the Mark 1 Prius.
Is there still a chance to revive the car?
Oh certainly. But you'll have to learn a lot. Fixing this type of car is not for the average Joe.
Or should I just sell it to the junk shop?

That seems a waste. If you sell it cheap, please at least make an effort to sell it to someone who can revive it, not scrap it or let it rust. For example, some people here may be willing to buy it from you. I might even be able to find some space myself. It's up to you whether you want to take a financial hit (or lose a financial opportunity if you already got it cheap), or want to learn enough to fix this car yourself.

Be aware that high voltage DC will be involved; if you don't feel that you can safely handle that, then fixing this class of car is not for you.

[quote="Simon"] Does the turtle ever go away after the cars been running for a while?

>>> The turtle doesn't go away(this happened 3 weeks before the car died). Normally after a few days, the turtle would go away.


I was successful this arvo in starting the car. It ran for a few metres before the power was cut off, but I was able to bring the car back to my garage. I really think that it's the battery pack that's causing the problem. Image

Hi Matt,

It is only the "minor service" that Toyota did to my car like change oil, top up coolant, replace the battery etc....but they won't touch the hybrid battery. They tried to rectify the issue before when I first sent it to them for service but they weren't able to do anything because their computers cannot read or recognize it....

The car is well looked after and regularly serviced...

Hey Simon,

I think the problem with my prius is just the 12V auxilliary battery. Because since Toyota replace the old battery, it started to play up on me and then eventually died.

My question is, would you be able to tell me the actual "right" type of battery that I should buy for my prius?

Could you please tell me the best brand and its specifications if possible.

Your response will be highly appreciated.

Regards,

Kristian

Hi Kristian
I am not sure what is the proper 12v battery for the Prius I will check my car tomorrow.
But I doubt that the 12V battery is the cause of your problems.
Unlike a conventional cars battery the Prius 12V battery doesnt have to do a lot. AFAIK It really only has to start the computers up and then all the power comes from the traction battery to start the ICE and the DC/DC convertor handles all the 12V loads.

Well, when you write it like that, it seems plausible. However, at least on the NHW10s, it seems that 12 V battery issues frequently did cause traction problems.

Replacing the 12 V battery seems like a pretty easy and relatively cheap step that can't hurt, and probably needs doing soon anyway.

[ Edit: I don't know if this continues in the NHW20 models, but it seems plausible. ]

Another Prius followed me home a couple of weeks ago. It's a 1999 model that stopped running 3-4 months ago.

I dismantled the battery packs and swapped out the sticks that had leaked with some from my other dead Prius (with terminal transaxle problems). About half of the 40 sticks from the new Prius showed signs of cell leakage.

Charged up all the 7.2V sticks slowly with a couple of RC chargers and got my new Prius running again. Image

It is still not a healthy battery pack though. It goes from half charge to full in no time and turtles come up with fast acceleration.
Turtles also tend to show when accelerating even gently after having regened/stopped at a red light which brings the battery to full on the mfd. Then it tries to use lots of electric assist and drops the battery to yellow and then the turtle comes up. But it quickly recharges and the turtle goes away.

I found pressing the AC max switch helps if you find yourself stopped with a full battery because it will fire the ICE up which will help to reduce the amount of electric assist when accelerating.

Here is a video of the Prius behaviour http://www.youtube.com/watch?v=Su_C3UbNVU0

Hi lefty, the battery clinic repair and recondition Prius packs but costs a lot in freight. Hopefully soon I will replace my aging Nimh pack with a new Lithium one.

Hello Simon,

I have just acquired a dead nwh10 Prius and I was wondering if you have any advice regarding getting the batteries recharged/replaced.

I am repairing the car in preparation for an EV course I am conducting. The Prius will be converted to PHEV as a training exercise.

You can contact me on my work email mark.hemmingsen@cit.edu.au.

Thanks,

Mark.
