I replaced the battery because I was getting the red triangle with no screen powerup. This is a slight improvement but I'm stuck as to what the "Problem" indicator on the MFD is about.
I've checked the battery in maintenance mode, reading 12.6V.
I changed my oil, oil filter, air filter at 90k for a trip to Miami this past weekend. Uneventful on the way up. On the way back, stopped and did some shopping before hitting alligator alley to come back home. As I got on the alley after paying the new $3 toll my 05 prius with 90k miles on it would not go over 65 with my foot on the floor and the battery on the mfd was in the pink. So I drove to the nearest exit, checked the fluids etc, all good. Got back on same thing so I put on hazards and stayed on until i could get off on a much slower road. I was going about 55-60 and it would go no faster.
As I got to a place I pulled over DC'ed the negative battery cable and let it sit for a half hour. I then attempted to get going and it seemed to be running fine until I attempted to pass a car and the car seemed to lock up and lose all power, check engine light came on and the red triangle light came on. I pulled over and let it sit again. I then got it to a gas station with the check engine light on. I put a few gallons gas on and tried to limp it home. It made it home and the battery seemed to recharge back to all the blue it can get to, but has yet to hit the green.
Bought a 2011 Prius three just before the 2012s came out. Can the audio system in the 2011 be repalced with the 2012 touchscreen w/o nav and still function with the steering wheel controls?
View 6 RepliesI had the red triangle pop up on my Prius. I codes I got P0A93 and P1121 I needed a new control valve and inverter water pump. I installed both the valve and the inverter pump filled it with new coolant and bled both systems.
I went into maintenance mode so I could run the motor and bleed out all the water. My question is the red triangle is still on in my car when I start it up.. Is there some way to clear the red triangle or does it just go away on its own? Not sure what to do.
My car Gen.2 was 200K. I change the water pump and thermostat on 150K. The reason to change the parts because I think my car a lot of miles. The car run great no problems. Till last month my car had overheat on freeway at night time. The temperature up to 245 F have the red triangle on dash and thermometer icon on Navigation screen. Before overheat on same day on the daytime when I take off I heard sound water running in the engine. The day after I check the level coolant in the reservoir tank was full but in the radiator need to fill up the coolant. After that when I drove the car the coolant overflow form the reservoir all the time. I have to check and fill up the coolant in the radiator every morning. I been the many shop ask them about the symptom of my car. Some they told me water pump failure, some said thermostat failure open all the time or some told me head gasket leak. I check all the engine didn't see any leak but I saw coolant overflow from reservoir...
View 5 RepliesMy mechanic installed a new Hybrid battery in my 2005 Pruis using the repair manual and a video that showed him how to do it. He also replaced the harness and the ECU battery. When he tries to start the car all of the lights light up on the dash but no ready light on the start button and the car will not start. The instructions did not say anything about this issue so he is lost! He thinks the smart key and the ECU have to be synced in some way but doesn't know how to do it. (none of the books covered this.
View 1 RepliesThere is no electric power (no lights, no dash indicators, no starting, nada...) New battery just put in.
More background: old 'beater' hyundai, manual trans, not sure of year but older one (looks a lot like the picture for this forum). It was sitting in storage for over a year and was driven in to that slot. It belonged to my son's friend who just gave it to him. Was going to drive it away (tires, oil ok) but of course would not start. no lights will come on, interior or exterior. turning key in ignition to any position makes no difference - still no power to anything. Battery cables seem ok. Could find no blown fuses, either inside or under the hood.
So, what are we missing? What is the magical fix that will quickly get this thing on the road (we want to stop the storage fees too).

View 6 RepliesI purchased a new 12 volt battery from Toyota and installed in my 2009 Prius. My car wouldn't start. So, next I tried to jumpstart it. I pressed the Power button (the light was GREEN) but it wouldn't start. I pressed the Power button again (The light was AMBER) and the hybrid drive engaged and the CHECK ENGINE light came on; however, the engine didn't start, the dashboard didn't light up and the READY indicator did not appear.
Next, I grabbed the Owner's Manual and went through the Troubleshooting sequence. Engine still wouldn't start.
Install new HV Battery in 2005 and now I have no dash display lights.
View 2 RepliesI decided to install a new Optima yellow top battery because I performed the battery check and found the voltage low and therefore believed my 2008 was still running on the original OEM 12v battery. Much to my surprise I found a non-OEM battery installed and the vent tube elbow missing!
View 10 RepliesJust put in a new 12v battery but when I try to connect the ground cable, I'm getting sparks, indicating a current draw. And the horn starts blowing nonstop.
View 6 RepliesI just bought 05 prius from a dealer I don't know the history was told all it needed was a hybrid battery.
Now I have a 05 that I drive with known good parts so I pulled my hybrid battery and installed it in the new car the monitor showed engine charging inverter then going to the battery. However the bars on the battery graph start dropping. only code is a engine code 2102.
I also noticed the old A/C condenser in the back.
Working on a 2010 with 156k miles that threw a P0A80 on two separate occasions. Once before the 12v battery was changed, then the day after the 12v change. Decided to change the HV traction battery today with one from a wrecked 2014 with 56k miles.
After changing the HV batt I started getting the yellow triangle with no code associated with in. I would clear the code and drive the car a few minutes and then the triangle "check hybrid system" would appear.
I have an 07 and replaced the HV battery. Before swapping battery, I had Red Triangle, (!), VSC, Check Engine (took car to dealer who diagnosed it as needing HV battery). Now new battery is in but error-icons remain. The LCD display shows battery as more that half-charged. I connected an old Actron ODB2 scanner (circa 2000), but it doesn't Read any codes and doesn't Erase the codes causing the problem.
View 5 RepliesI had my Prius check out and gave me these trouble codes couples battery's low he has a red triangle ....
P0A78
P3000
P0A80
P03014

The battery's rating 13.5 volts. Will always trouble codes go away after replacing the battery I added inverter to it because it was it was dying after 50 miles per hour then it slowed down??
I recently cleaned all of the corrosion off the copper bus bars on my traction battery. When I got everything put back together I went to start the prius up and got the red triangle. I then remembered that I forgot to plug the master orange switch back in. After doing so I still had the red triangle so I turned the car on and off a couple times and it went away. Is this normal behavior from forgetting to put the master switch back in an attempting to turn the prius on?
View 6 RepliesI always try to save gas in my Prius so I hit the Ev button whenever I'm in the target parking lot. Overall my Fuelly is 51.9 mpg. Today when I got into the car I hit my Ev button and it said "battery too low". Do you think my car is starting to have problems? I also hit the power control a lot too.
View 7 Repliesi have a 2006 with almost 200k miles. Got the red triangle, check engine light, and the red car at the top of the MFD. I ran the codes and got P3000. Does this sound like traction battery failure? The car still turns on and ICE still cycles off and on.
View 19 Replieswell I saw one other thread on this topic but no resolution. I replaced the hybrid battery like the codes told me too on my 2003 prius and it now drives great but as soon as it start it shows a problem and the red triangle stays on. No check engine light, no codes, no driving issues just a red triangle. How to diagnose a red triangle when there are no codes.
View 16 RepliesI'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.
