Prius (Gen 2) :: Red Master Warning And Yellow Braking System Lights - Code P0A08
My 2006 prius has the Master warning light(red) and the braking system light (Yellow) on while I am driving, and I went to the dealer.
The technician told me that he could not verify any warning lights ON at that moment, and he performed health and diagnostic checks on it. He inspected connection at auxiliary battery and junction box 1. All checked OK at this time. No repairs recommended at this time.
However, the master warning light came on when I pick up the vehicle. The dealer told me that they will inspect it again tomorrow. And they found that there a P0A08 error code. They suggested me to replace the hybrid converter/inverter.. My car can still drive while the lights ON.
Prius (2004-09) :: Indicator Lights Intermittent - Code P0a08 And P0a09
..few days later having some problems: red triangle, vsc, car with exclamation point. Took the car to toyota and scan came back with codes p0a08 and p0a09. Toyota diagnoses as needing a new inverter converter. However, the indicator lights are very intermittent and the car shows no real symptoms. I should mention the HV battery and 12v battery are brand new. Does this seem right needing a new inverter converter? Could it be something more simple like wiring/harness to converter?

2013 Prius C THREE 67k miles
Got out of my car after using it friday. hopped back in to go to work tuesday was getting," Check Hybrid System, stop and pull over immediately". I put about 30k miles a year on my car so i run it hard and I am probably due for oil change and tranny fluid drain and fill but other than that because the car was working fine friday. I tried going into accessory mode then holding brakes and powering up, I forget what that's called, but no luck
Towed it to my mechanic, he said that he was getting generator errors (and tsp or tsb things?) and that he could most likely do the work but that I should make the dealer do it because it may be under warranty and didn't charge anything. So got it towed to the dealer and after the hybrid tech got in they said they see some generator error but they can't reset it. But also mentioned they got the car to come on.
Prius (2010-12) :: Check Hybrid System Came On - Code P0A94 And P324E
Just posting another 'Check Hybrid System' thread. 2011 Prius with 68k miles on it. Had not had the E0E recall done before. Turned the corner out of the supermarket on Friday, and the car lost all power. Coasted to a spot on the side of the road and all the lights lit up and 'Check Hybrid System' came on. Prius would not restart at all. Car is driven approximately 80 miles a day, mostly flat land, weekends usually spent in mountains. Had it towed to the dealer, they pulled P0A94 and P324E. Didn't replace the whole inverter, but looks like the repair kit, including 04899-47021 Transistor Kit replaced. Got the car back and seems to working as before. Will check mpg over the next couple of fill-ups and update if anything seems different.

My new-to-me (bought in May this year) 2010 Prius last night suffered. Nearing home on my usual 21-mi commute from work and on a secondary road, I was stopped at a red light. As I normally do when at a red light when a rather spirited start isn't needed (no or few cars behind me, not uphill, etc) I pushed the "EV" button to take advantage of electric acceleration up to 25 mph. All seemed normal as the light turned green and I started off. I don't know if I reached 25 or not - must've been close - when all of a sudden the acceleration stopped as if I'd taken my foot off the pedal when indeed I'd not. Simultaneously, a circus of lights lit up on the dash along with the fairly ominous message of "Check Hybrid System."
As with all things electronic these days, I figured a good ol' fashioned reboot was in order. Turned it off and back on and...same thing of course. Being near an intersection and a very bad place to be stopped - and not knowing if the car would actually move - I pressed the accelerator anyway, despite the warning lights, and indeed the car started to move. It seemed to cap the speed at 12-13 mph, which immediately seemed like some kind of self-protective safe mode. Luckily, I was within spitting distance from home, so I limped the last 1/4 mile in this state - and at 12 mph.
There are probably 5-6 warning lights on in addition to the big "Check Hybrid System" message. Let's see, first and foremost, the yellow triangle of death, followed by what I think is the Slip indicator (car icon with wavy lines), the CEL, the encircled exclamation point which I think is the braking system, and I forget, a couple of more. I should've snapped a pic but I was in a hurry to troubleshoot.
So I used my Actron scanner to pull the P0A94 code. I didn't see that it's able to read the sub codes, or maybe that's a capability that only the expensive dealer scanners have. Anyway, I can't conclude what it is other than the generic "DC-DC Converter Performance". I know that here and elsewhere there's a list of all DTC codes, and I saw that this code has 17 sub-codes, many of which are related somehow to the inverter, which seems to have been the subject of a recall in Gen II models (acutally the inverter cooling pump IIRC) but not on Gen III.

I have a 2008 Camry Hybrid and recently got a "Check VSC System" warning light. A diagnostic resulted in a C0210 error code. The code is for a right rear speed sensor malfunction.
I had a local shop look at it and he replaced the hub accembly including the speed sensor. It didnt work. He and I took a ride and on his diagnostic tool, the speed reading for the right rear wheel was all over the place.
The next day he replaced it thinking that the new sensor was bad. This worked, however only for a day. Now the light had come on again with the same error.
Prius Plug-in 2012-15 :: Check Hybrid System Message While Driving On Freeway In EV Mode - Code P03CE
Yesterday while driving on the freeway in EV mode, my PIP (one of the first delivered to the states) flashed the "Check Hybrid System - Stop the vehicle in a safe place" message. I was near my house so I just went home. My SG2 showed code P0C3E, which is apparently an inverter over temperature code.
Took it to the dealer this morning and they just informed me that the car needs a new inverter, but no other details… "internal fault" is what he said.
While googling, i found this recall notice:
Green Car Congress: Toyota recalling about 701,000 Gen 3 Prius vehicles in US over software issue in inverter assembly
that doesn't talk specifically about the PIP and implies that it is a software problem, but goes on to say if the car is in a fault condition the inverter will be replaced. of course, it's possible that a software problem leads to hardware damage.
Prius (Gen 3) :: Check Hybrid System Light Came On
So a little over a month ago, I was driving my 2010 Prius (about 42k miles) when the Check Hybrid System light came on. I lost power and my car was stuck on the road, as I was unable to get it into neutral. So I called a tow truck and was towed to my local dealership. The dealership ran some tests, thought it might have been the throttle body. They switched my throttle body with a loaner prius to see if this fixed the problem. The new throttle body worked in my car and my throttle body was put into the loaner and functioned fine. Then they ended up fixing a TSB for the electronics in the car. I was told the problem was resolved and I could pick up the car about a week later.
After picking up the car a week later, before I could even drive away from the dealership, the Check Hybrid System warning came on again. I talked with the service manager and left my car to be fixed again. They checked all the systems and were still unsure what the problem was. Eventually they made sure all the connectors were properly seated and test drove the car and ensured the problem was gone. About two weeks later, I was told the car was fixed and I could pick it up.
After picking up the car, I was still unsure the problem was fixed, but I was told that was all I could do. After having the car, for about a 1.5 weeks I was on the highway. Once again, the check hybrid system light came on and I lost engine power. Luckily, I was able to pull over from the left lane without causing an accident. Once again, I had the car towed to the dealer and now I am waiting to hear back from them.

I ran out of gas in my 2011 Prius and immediately all warning lights came on as well as the "check hybrid system" light. After filling the gas I read similar threads on here and trouble shooted the battery. 12v Battery tested good, so now what is the next step? I also did a reset on the 12v battery and that didn't work.

I have a 2013 Prius Persona with about 5,300 miles on the vehicle. Just recently had the 5,000 mile service taken care of at a local toyota dealership. The very next day I tried to start my vehicle with no prevail. My instrument panel indicates "check hybrid system" (!) the car will not start, nor will it shift into drive or reverse, only into the neutral position. Made several attempts to turn vehicle on and off and tried to jump start. Still no luck. Had the car towed back to the dealership. Mechanics are still trying to identify the problem. What may be the cause?
View 5 RepliesPrius (2004-09) :: Getting Hybrid System Warning Light?
My wife just called and said this light came on. She said when it came on the car turned off its cruise control but kept running. Now she says it seems to be running fine but the light is coming on.
The car has around 110k miles and I just replaced the spark plugs, air filter and engine oil about 1k miles ago. What it could be? I'm going to have her pull codes at the auto parts store but she needs to do about 20-30 miles of driving today for work. Is it safe for her to do so?
Prius C :: After Adding Fog Light Getting Check Hybrid System Error
I added fog lights, and I removed the fuse box and body computer to do so. I disconnected the 12V battery for most of the work, but later I did pull a couple of under-the -dash connectors with the battery connected.
Now I get the screen saying "check hybrid system", "don't drive". I've tried the turn-the-key-on-three-times technique, and I disconnected the battery for 30 mins. Still the message persists.
Using my Torque app, I can clear the ECU fault and the message disappears. However, when I start the car the next time, the message is back. Everything else seems ok.
I checked all the cabin fuses and most of the engine compartment fuses. I took everything apart again, and double checked the fit of all the connectors under the dash. It seems that I have thrown a code which keeps popping up every time I turn the ignition on.
Prius (Gen 1) :: 2002 - Hybrid System Warning Light Just Came On Screen
I was driving to work yesterday and all of a sudden the "Hybrid System Warning Light" just came on the screen. I didn't notice anything different and drove it the same way. However, when I checked the energy monitor screen, the battery was low on charge. It came back to normal in about 5 minutes, but the light is still lit up.
View 9 RepliesPrius (Gen 2) :: Red Hybrid System Warning Light / P0A93, C1300 Came On
My 2007 just came due for an oil change a week ago (Maint Reqd stays on), not that it matters. Yesterday the Red triangle of death, Check Engine, and brake warning lights came on. We drove another 15 minutes (city) without incident. When I turned the car back on the brake warning was off (and has stayed off) but now the Info Display has the red Hybrid System Warning Light also showing, along with Mr. Triangle and Check Engine.
This morning Autozone read out the P0A93 (confirmed) and C1300 (current) codes for me. With the car "Ready", I can see fluid movement in the inverter coolant reservoir (not sure it qualifies as "turbulence") and feel vibration in the line connected to the pump which is humming so quietly. The 12V battery shows 12.5V with the car off and 13.5V with the car on. Does this mean the inverter is still operating? (I read the P0A93 code is supposed to shut it down.)
I did find the ICE coolant reservoir dry and refilled it with SLLC. There looks to be a small leak in the water pump, but I'll deal with that later.
Prius (Gen 3) :: Hybrid System Overheat Warning Light Comes On Regularly
Last summer I had a catastrophic experience on a family vacation when my wife's 2012 Prius overheated on the highway and lost power. The dealer that we limped into kept it for a week and couldn't find any concrete problem, except to say that since it was a salvage vehicle rebuilt without Toyota brand parts, that all of the cooling system would need to be replaced. I waited until we barely made it home and had my mechanic replace the inverter pump.
Since then the "hybrid system overheat" warning light comes on regularly, especially when driving up a long climb, even in moderate weather. There are no codes. Is it possible that there is air in the lines? My mechanic says that it feels like the inverter pump is working, tho I don't see turbulence in ready mode. A link to bleeding the air?
Prius (2004-09) :: Hybrid System Warning Light And Running Out Of Gas
My hybrid system warning light came on last night in my 2005 Prius with about 89,000 miles. The car may have run out of gas (I wasn't driving). This car will only take about 8.5 gallons when the fuel light starts flashing. I started it this morning, light was still on, only 2 bars on battery, my car usually runs near the green, and the gas engine stalled after about 30 seconds. The gas indicator was flashing, so I added a 1/2 gallon I had at the house, and unplugged the 12v for about 10 minutes to clear the system. Upon restarting, fuel light was still flashing, but no hybrid warning light. Drove a few miles, filled up with gas, and drove another mile.
So my question, could running out of gas and driving a very short distance (light came on as my wife turned into our driveway), cause this warning light to come on? If so, will there be any lasting effects? Did unplugging the 12v battery clear the computer codes, or can I still get these read to learn more about what happened?
