    I have a 2007 prius with 175k miles.

    I'm having intermittent Red Triangle while driving. Comes on every 20-75 miles. I have unplugged the 12v a few times to clear it so my car will start. I'm getting B1200, B1207, B1271 Codes (no current malfunction) under Gateway. I'm not sure how old these codes are. I've been driving the thing trying to get the dash to light up again so I can read the codes. It's been a few days and all is well, but that triangle is going to come up eventually. I recently had my hybrid battery replaced. No other problems. 12v battery is pretty old but voltage seems to be ok. Is the car ok to drive for now? I would appreciate any help. Thank you!

    Finally got techstream working.

    Generally speaking, no. Continued driving could cause additional problems. Once you know what the problem is you can make an educated decision on whether or not to drive the vehicle in its current condition.

    Every time you disconnect the 12v you will lose the codes (DTCs) that were stored in the various ECUs.

    Which OBD2 device are you using to read the DTCs with, is it still Techstream?

    Have the checked or cleaned the HV battery fan lately?

    Have you checked to make sure the inverter coolant pump is functioning?

    Here is the workup for DTC B1200 : https://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/Repair%20Manual/04pruisr/05/21acw/cib1200.pdf

    HV fan was checked and was clean/clear. I checked the inverter pump - all good. I re-seated the orange safety latch on the hybrid battery. I've been monitoring temperatures of different systems - all good. Using Techstream to pull codes, and also have been using a bluetooth obd2 device to monitor systems in real time. Checking oil weekly, was just changed. I'm prepping to change the transmission fluid and spark plugs. Funny you should mention possible critters chewing my wires, as the 12v battery ground wire (i guess thats what it is, single white wire into battery.) has small holes exposing wire which i wrapped with electric tape. As of now I have driven 100 miles with no dash lights...

    Mileage is good, new hybrid battery is strong. everything sounds and runs perfect...i'm not driving more than 10 miles at a time to work and back. Guess ill trust that it's ok, until triangle is triggered again.

    Appreciate the responses.

    Ok. So Triangle came on today. Codes are:

    P0AA6 - Hybrid Battery Voltage fault - Sub Code 612
    C1310 - HV Malfunction
    C1259 - System regenerative malfunction.

    I read the 612 code is the hybrid battery.

    My battery is under warranty so im really hoping its a bad battery....if its anything else UHG.

    Unfortunately the guy I spoke with about the warranty said my check engine light needs to come on to indicate a bad battery...which sounds like rubbish.

    Yes it's a rubbish excuse. But with many refurbished batteries, the warranty is only good if the company/person is willing to honor it.

    For the reported INF code (612), the image below will give you a better idea of the problem area and how to proceed :

    Do you guys think I should open up the battery pack and inspect it for a cell leak?

    What would you do if you did find one? I'm not sure I would take on the task unless you have the knowledge and equipment to fix it

    I just want proof that there is an issue with hybrid battery, so warranty is honored.

    But the argument can be made that you opened the case and messed with the battery so warranty denied.

    Either way you lose. So I guess you should just open it. Looking for a leak is very difficult unless you disassemble the entire battery. Good Luck!

    The triangle is a check engine light, or as good as one. Who is this battery rebuilding company?

    So to drive the car you have to disconnect the 12v to clear the codes, and when you disconnect the 12v the codes needed for warranty replacement go away?

    You bought a Used battery....there's the problem.

    Do not open it up or mess with it in any way.

    Bring it back to the place you bought it.

    Bring your wallet along for any additional charges.

    Can you share approximately how much the used battery cost?

    Pretty sure this is the source : hybrid-reconditioning on eBay - and was also used in this thread : Keep my core? | PriusChat

    Currently around $800, though the price has been lower in the past. Comes with a one (1) warranty, and NO RETURNS.

    One listing includes free installation, which may be at the sellers "pick up only" location. The other offers free shipping.

    No upfront core charge, though you must give them "a recondition-able trade-in battery" or be charged $500 extra.

    Seller has decent feedback, which means the batteries must be making it past the ebay 60 day limit for posting feedback :cool:

    UPDATE:

    I spoke with the guy from Hybrid-reconditioning. They are coming to replace my current battery with another reconditioned on Monday. They were very nice and accommodating. Happy I didn't need to have it diagnosed by a dealer. I would feel terrible if it's something other than the hybrid pack. But i'm pretty confident it is. I'll update if problem is resolved.

    I paid 750 plus tax and they drove 120 miles to install. I would be very happy to get 3 years out of it. But after warranty is out it's a toss up...
