Bought used 2005 Prius, potential battery failure?

12 volt battery in the trunk is bad...replace it and clear the codes, should be OK
or return the car to the dealer and get your money back

 

my opinion is there are more problems than just a 12v battery issue.

 

Yep.
Start with the 12v battery.
Will cost around $200 for the battery plus installation.
How do you know the codes? Do you own your own reader?
Or is the car lot reading them for you?

 

i think the p3013 code is for a coolant valve .. see if theres any movement in the pink coolant bottle at the center of the car, if not you have a big problem...the pump hasn't been moving coolant through the invertor and its damaged it and the battery pack..might want to return it and get the cash back.

 

Ummm, can you go back to where you bought it and get a 12v?
P3013 is hybrid battery related, though.
Does your code reader read hybrid codes like P0A80?

Contact me offline (call or email) and I can check to see if bad hybrid battery was reported to the Toyota dealer.

 

Nothing good is going to come out of buying a refurbished 12v battery. Test the 12v battery that in there first, if it's bad, buy a NEW one.

The reason I think there are more problems is simply because you bought the car that someone else just unloaded. Most of the time, owners don't unload a good car with just a 12v problem.

 

I just sent you how to check it yourself with the lights on/off 3 times trick.
Same as what I posted here

From your email, the 12v is within specs.
So then that is bad news....

P3013 is stating that one of the modules within the pack is failing.
P3030: battery voltage defective, line snapped

The p3013 may be a false error if the p3030 is correct.

I have seen where there is a break in the harness that makes it (falsey) appear that a VBlock is going below spec.
To confirm it, though, requires some serious taking apart of the hybrid components.

 

p3013, opps I thought it was a valve code...my mistake

 

If you are not using mini VCI ($20-$30 on Amazon/eBay), then there may be more codes your current code reader CAN NOT read.

Many threads on mini VCI install help and etc. It requires the use of a laptop (32bit OS so XP ideal).

 

+1

You can see the block voltages. A sensing issue (broken wire) will be readily apparent, and tell you where to look.

 

Yeah a lot of corrosion in there.

Pace, I'd say that you've got an open circuit in one of the crimp lugs on those sensor wires coming from the corroded terminals.

 

You remove the wires from vblock 3.
Inspect and test them end to end for continuity.

 

NO.

To get ALL the codes, you four choices:
1) Your Toyota Dealership for a diagnostic fee of $99+.
2) Acquire mini VCI and have a spare laptop.
3) Find a business that is using Techstream to pull all the codes; independent Toyota mechanic and a likely diagnostic fee.
4) Find someone who has Techstream and mini-VCI cable.

Techstream is the software made for Toyota, to read Toyota/Lexus/Scion codes; thus your current OBD2 reader is inadequate. Techstream requires a proprietary OBD2 cable, called MongoosePro. This proprietary cable is available from DrewTechnologies for $495. Drew Technologies : Introduction

Since you really don't want to pay $495 for this proprietary cable, buy a knock off called "mini VCI" from Amazon/eBay for $20-$30. These knock offs come will come with hacked copy of Techstream software. You can always find the latest version of Techstream somewhere; version 8.0 is sufficient to work on your Gen2 Prius.

For your safety, just assume the software has viruses, malware, etc, reporting your every keystroke back to a criminal organization. People who have installed this on their laptop report their anti-virus program going crazy. Thus the use of a spare laptop that will only be used for Toyota diagnosis, and never used to log onto the Internet with confidential info (email, banking, etc). This being said, many here have been using hacked Techstream and mini VCI w/o any issues.

There are lots of sites that have Techstream installation suggestion and trouble shooting, its a matter of you actually searching.
