Prius (2010-12) :: Disabled - P0A94 Code And Check Hybrid System Message
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 just bought a used 2012 Toyota Prius iTech from a country town 3 hours away. About an hour into the drive home, the display informed me to "Check Hybrid System" and then "Check PCS System". The car continued to function for a little while, then eventually lost acceleration, so I pulled over. I turned it off and on again; the warning light remained but the car started and continued to work, but soon after I lost acceleration again. This happened one more time.
Then I Googled the problem and discovered that you could "turn it off and on again three times to reset the computer". I did this and the problem disappeared and did not resurface for the remainder of the trip, and has not happened again since.
Prius C :: Code Check Hybrid System Came On
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.

Just started up my car and the "Check Hybrid warning system" came on, along with a check engine light. The car starts and moves, but I'm unsure if I should drive it to the dealer two miles away without doing any further damage to the vehicle or have it towed. The car has 130000 miles and is serviced every 5000 at the dealer with all recommended maintenance performed.

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?

I cleaned out hybrid battery cooling fan today, not too bad after 160K . However, as I test drove prius the Triangle of death and "Check Hybrid System" message pops up.
Drove 13 miles back home, battery charged good. No power consumption data given on hud. Rechecked fan connection and looked over area. All looked good. I dont think ICE was running during drive home. Tested 12 volt=good. Disconnected 12 volt and orange plug. Reconnected. System reboots and seems Ice goes through warm up. Even put in power mode and it roars. Scratching head on this. Coincedence or maybe I should have disconnected 12volt before disconnecting cooling fan?

Prius (2010-12) :: Check Hybrid System Light Came On - Car Inoperable
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.
Prius (2010-12) :: Check Hybrid System Illuminated On Dash
A few days ago our 2010 with 87k became immobile with "Check Hybrid System" illuminated on dash. Dropped it off at the dealer who had it all day. Replaced the "transistor kit" part number 04899-47021 and blamed the failure on the recall. Recall was not completed. Wife felt a jolt while driving home but no warning lights illuminated. Next day she tried to start it and got that message.
Codes pulled were p3004 with info code 800 and p0ad.

Prius (2010-12) :: Check Hybrid System Warning When Try To Start It
We bought a used Toyota Prius 2012 with about 35,000 km in early August 2015. We shipped it overseas. It gives the "Check Hybrid System" error when we try to start it. All the lights and instruments work o.k.
I've read this car be a problem if the car is parked a long time, which it was as it was mostly in a shipping container.
Prius (Gen 3) :: 2010 Slow Down And Stopped - Check Hybrid System Error
So I bought a 2010 Prius IV from a nearby dealership today. I had test driven it twice before buying, but when I was taking it home I got the error "Check Hybrid System," and the car slowed to a stop. I had to call the dealership to come tow it back and it's being serviced right now. I'm mostly venting, but also more than a little concerned. I checked the orange clip/wire in the back and it was connected properly. What this could be and how big of an issue it really is?

First off I have a 2010 with about 11,000 miles and it has been running great since I got it. This morning I was greeted with the "Yellow triangle" and the "check hybrid system warning". The car started fine and I pulled out of the garage under battery as usual and then the engine kicked in also as usual, everything seemed normal except for the warning lights. Since I have a long commute I just took my wife's car and got to work and did a forum search on this issue. I called my wife and had her turn the car on and off three times and she said it cleared the yellow triangle and check hybrid system but it still had the check engine light on. She also said the car seemed to be running fine and shes driving around town in it. I couldn't find anything on the check engine light. Is it ok to drive it?
