Prius (2004-09) :: 2006 - P0a80, C1310 Keeps Coming After HV Replaced
Jul 10, 2015
I have a 2006 Prius, It has 165k miles. Recently it gave me a code to replace hybrid battery pack, I read this code with my scanner from HF. I have changed out a battery pack with replacing the bad modules before so I am not a bigger with the system. I took out the pack and checked and it seemed like all the modules are in the 7.8 range. This was confusing since the code reader was saying to replace the battery pack. I put it all back in the car and tested it again and got the same results. It seems like the HV system is not being recharged any longer. It seemed odd, normally when I remove my foot from the gas the system shows the car regenerating power.. Now when I step on the brakes I only see that. The system does charge but randomly it will drop down where there are 1 to 2 bars left and then charge back up again.
P0a80
C1310 malfunction in HV system (when i read about this people say this is a ghost code that comes up from the battery pack.. but maybe not in my case.

The Prius has 115ooo miles. It is a 2005. Just recently it started showing the red triangle of death, check engine light, and the brake light. When I check for codes using a scanner it comes with the following:
P0A80
C1310
C1259
P3015

Have replaced dead cells on wife's HV battery over a month ago. Threw this P0a80 code today and will barely move. She idles into dealership and they say it's the battery, really!

I have 2005 Prius with 300k miles. I started throwing P0A80 code. I removed the battery and checked all the modules and found 2 of low voltage, ordered them from Ebay and replaced them. I placed the battery back in the car and started the car but got P0A80 code again. I purchased the grid charger from Hybrid Automotive and connected it according to their instructions for 24 hours. I drove a car but got the red triangle again and P0A80 code again. I removed the battery again and tested the voltage of all the modules and these are the readings:

A couple months ago, my car suddenly got the red triangle. The dealership said that I needed a new battery, and eventually a new water pump. I couldn't afford $4500 as I bought the car just 9 months earlier and am making payments on the car.
I found a guy that was to "recondition" the battery, which set me back about $1200+. After getting it back, the car has been making a rattle sound in the engine bay when under acceleration (it sounds like a loose screw, but I don't know).
After about a month, I got the red triangle again. The car's performance deteriorates, the state of charge fluctuates a lot more. One minute it is green then literally a minute later it is purple then green again. The guy that reconditioned my hv battery said all the cells are good but for some reason became unbalanced, so he put it on the grid charger and rebalanced it (I believe it was on there for about 24 hours).
2-3 weeks later, it happens again. Same thing, the guy says it is unbalanced again and stuck it on the grid charger (because of time constraints, it was only on the grid for about 5 hours).
Then again 2 weeks later it repeats itself. A couple days before it happened, I tried out the elm327 adapter, custom pids, and torque app. Before the triangle came on, the delta state of charge got to about 0.9% and was charging up to just about 90% and down to just below 39%. Same thing though, from high to low in a matter of less than a minute. Same code P0A80. Sitting on the driveway, all 14 modules would be consistently within .2 volts. But when the car started acting up, I saw a voltage difference of about 3 volts between highest and lowest modules. The repair guy said the same thing again. The cells are good but got unbalanced again. This time he recommended for me to leave the car for the weekend so it can sit on the grid charger for a minimum of 24 hours, which I did. I picked it up yesterday and it's driving fine right now.
He is also recommending that I buy a grid charger and charge the battery every couple weeks to avoid these problems. I mean, how do I know if he actually reconditioned the battery, or has just been resetting the fault code and grid charging the battery? Btw, I did the auxiliary battery test and it was perfect. I don't know when the battery was last replaced but I believe with how strong it is, that is was done sometime recently before purchasing the car late last year.

Yesterday I got the "red triangle" and check engine light along with these 3 codes:
P0A80 - replace hybrid battery pack
P3019 - battery block 9 becomes weak
P3000 - battery control system
In April of this year I have the entire battery replaced, in September I got the triangle again and one cell was replaced under warranty. My warranty is good through April 2016, however I'm afraid that this new code P3000 is going to be something not included in my warranty.
What could potentially be wrong? This is a 2006 Prius with approximately 208,000 miles. I'm not sure this is worth it anymore especially if I have to keep putting in more money.

I have a 2004 Prius with 80k miles. Always has been a workhorse. Recently had a bad cell in the HV battery. Battery rebuilt with new cell and now works great.
Now it runs about 20 miles and then displays dash lights of red triangle and small exclamation (brake?) and VSC.
I took it to Advance Auto and their scanner reads C1310 'Malfunction in HV system'.
I actually replaced the entire HV battery again with the battery from my friend's car, and the 12V battery too, but no luck. Same error.
If i disconnect the 12v battery for a while, it will clear the code and the car runs fine for about 20 miles and then dash lights come on again.
Car runs perfectly, over 50mpg even with the dash lit up. What that code is?

OK, I finally resolved the bad skid control ECU, so I have no more codes relating to ABS sensors or pump actuator. Still get a C1310 when travelling at speeds over 60 for 10 minutes or so. After the car sits for a while, the idiot lights, triangle, ABS and brake lights disappear and the car runs fine. Except it has been whining at acceleration and deceleration a bit more than I remember. When I hooked up Tech stream, I got a P0A2B which is - Drive motor "A" temperature sensor circuit range/performance. Please tell me it isn't transaxle. Why does it only happen at high speeds? I can drive for 20-30 minutes around town without it triggering the dreaded red triangle.

My cars been stalling , won't drive up hills can't really get over 25 - 30 mph and I'm getting a sound from the fan in the back. These 3 error codes could mean for my 2007 Toyota prius

My 2006 is doing some weird things. I have gone through a couple of HV failures and each time if I got the P0A80 code there was always an additional code telling me what was wrong. Not this time. Some times the battery will sit there while it shows that it is being charged and not take a charge. i.e. not come up off the pink bars, Sometimes it will charge all the way up to green and then fall off dramatically This is really strange because it is not showing any other code other than a crank cam sensor. The 12 volt battery seems to be ok.

My car has been fine with no changes besides tires last week, its a 2006 Prius and yesterday I got lights on my dash, went to auto zone for a read out and got an HV error code. I was wondering what is the most affordable route for my car to get repaired. I don't notice any mpg differences and everything still charges and recharges as if the errors don't exist.

So from the beginning the car wasn't coming on. It gave me error "p" said my parking break was not working properly and needed to be on a flat surface in order to work. We jumped it and replaced the battery shortly after that. The car will turn on but the actual engine is not turning on. The display screen has a little car with a red exclamation going through it. The dashboard also has all the lights on. We have tried to jump it from the relay at this point but it wont start now to where before it would.

2007 Prius
I just replaced the 12V battery with an Optimus yellow top. The car still will not start. All dash lights come on, READY light does not. Car will only shift into Park and Neutral.
Battery reads 12.6 volts when not hooked up and 12.3 when cables attached to terminals.

I've a 2005 Prius with ~193,000 miles. It recently started throwing codes P3019 (Battery Block 9 becomes weak) and P0A80 (Replace Hybrid Battery). Codes were pulled with a laptop running Techstream and a mini-VCI cable.
Figuring I had some time, cleared the codes and only drove the Prius for short trips. At first things were OK, but of course the codes reset after a few days, and pretty soon they were permanent. And the car had very little power, battery fan running on high.
Then when slowly accelerating from a traffic light (there is no rapid acceleration in a gimpy Prius), there was a "BANG" noise, really loud. It sounded like someone tossed an M-80 at the car. Pulled over, didn't see any damage, though there was a strong "fireworks" smell like gunpowder outside the car. Started the car, it fired up fine, drove it home.
After a couple more weeks the car refused to start, wouldn't go into "Ready" mode. So finally I took the interior apart and opened up the battery case. Here is what I found (pic attached).
Moral of story - don't drive too far when you get the P0A80.

I've pulled the HV battery from my 2007 Prius with 144, 000 miles given recent Red Triangle of Death (P0A80) and looking to replace battery pack but want to rule out the ECU. I've searched the threads and found mention of testing the ECU but wasn't clear.
How to test the HV Battery ECU in or out of the car? Using a volt meter and light bulb, etc......I would really like to rule out the ECU before putting dollars in a rebuilt battery pack.

Was driving home from school yesterday and my 2005 Prius turned the check engine light on and the red triangle light. Plugged into the scan tool it read: P0a80. I have a hybrid battery ordered. It should be delivered on Tuesday. How long can I get out of this failing battery before the car is undriveable? The Prius is my only vehicle and I don't have a problem with installing the battery, I just I'm wondering if the car will just drop dead on me before the battery gets here? The car appears to be driving normally with no loss of performance or MPG.

2005 Prius. I just don't want to jump ahead to replace the hybrid batteries right away. Can I still drive the car, some place people say it is okay to drive then eventually it would get weird...

I had a 12v battery issue that I see common. 12V battery does not crank car. Jump car and works fine for a few days. I had this issue and it went away. Dealer said replace 12v battery, or just carry my charger pack with and use that unless it gets worse.
Jump ahead 2 months. I drive 50 miles each way to work 5 days a week. No issues. Yesterday, after my car sitting all day, I am backing out of driveway and get the red triangle. Code was P0A80. I looked it up. I cleared the code and was going to dealer if it came back. Today, after driving 50 miles into work, no issues, I get the red triangle. Code P3021. Fan started running back there too
My question : Would replacing the 12v battery useful for this issue?

I recently replaced my engine water pump at 164,000 miles on my 2007 Prius, the car sat for 3 weeks while waiting to gather needed parts, i.e., water pump, coolant and Airlift system for adding coolant fluid. After installing the new water pump the car ran rough for 5-10 minutes upon initial crank (parked for 3-weeks). I took a 20 minute test drive around the neighborhood that evening, outside temperature around 65 degrees F, and car ran fine. SOC looked ok, bars moving between Blue and Green, everything appeared normal.
The next morning, I backed out of my driveway and the Red Triangle of Death appeared on the dash so I parked the car.
That evening I hooked up OBDII ELM327 scanner using Engine Link and picked up 2 separate P0A80 error codes, 1 of them was pending. I disconnected the Aux battery for 3-5 mins to clear the error's, Red Triangle of Death was cleared, then drove the Prius for 20 minutes with no errors or alarms. SOC seemed to be normal. OBDII ELM327 scanner showed the HV batteries were charging at same level, 16.8V and Aux battery was registering at 14.0 Volts.
The next morning, after 20 minutes of driving the Red Triangle of Death appeared, and shortly after I experienced loss of power, with sporadic engine idle and interior traction battery fan was on. Luckily I had made it to work and was able to pull into a vacant parking lot.
I did notice that around the time the Red Triangle of death came on this morning the SOC dropped quickly to 1 Purple bar and was slow to charge then shortly after came the loss of power and sporadic engine idle followed by interior battery fan.

Bunch of warning lights appeared and the dealer said it's code P0a80 and they recommend replacing the battery. I'd like to try to fix this myself and would like to hear your thoughts...
Plan is to check the traction battery for corrosion and use a voltmeter to test the cells and replace if needed. Prius 2004, 158,000.
