Prius (2010-12) :: All Dash Warning Lights Came On / Check Hybrid System Message
Sep 16, 2014
My Prius yesterday while driving slowly (under 10 mph) all the dash warning lights came on(triangle, cel, trac control, brake). the gas engine started and the message came on that says: "check hybrid system". Today when I went out to check there only two warning lights on (triangle and cel) with the same message displayed. My question is can the vehicle operate without damaging anything if I drive it as is? I have read on several threads that the engine will not start if the hybrid motor(s) are not working. Since my engine starts and runs I have to believe the motor(s) are working.

Searched for threads about this error message, didn't find much substantive except 'check your gas cap'.

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?

I Opened my 2011 Prius trunk to get the tire wrench to take my snow tires off, and install my main tires and rims. When I went to start up the car after it was done, I have a "Check Hybrid System" Message on the MFD. I wondered if I'd hit one of the 2 orange items on the Electric drive battery, that was exposed in the trunk, and I can't get rid of the message. The car is not drivable, the system doesn't read "READY" and the engine doesn't start.

I was driving down the road and suddenly the car stopped. The check hybrid system light came on, and it wouldn't go forward or backward. I had to have it towed. What has happened? Is it included in extended warranty?

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 2010 Prius, currently at around 69,000 miles. Back in Feb 2015 (when it was just under 60,000) I was driving on a city street and hit the accelerator once a stoplight turned green - immediately as I took off (at a normal rate of acceleration) my 2010 Prius made a loud noise and I got the red triangle of death, with a "Check Hybrid System" message. The car quickly shifted into "limp home" mode and I was able to make it back home as I was only about a mile away.
Got towed to the nearest dealer the next morning and after tons of testing and going back and forth, they replaced the transmission and inverter (was able to get it covered under powertrain warranty), and I was on my merry way. No issues until last night.
Yesterday evening, I am on a city street and get a warning beep. I look at my dashboard and this time I have a yellow exclamation mark with the "Check Hybrid System" message yet AGAIN. Towed the car to the nearest dealer and am now waiting on next steps. Only update I've gotten so far is that they are still trying to diagnose the issue, and are getting 4 error codes in this process, 2 of which are new. I am waiting on the technician to tell me what the actual codes are - hopefully should get them tomorrow.
I would hope if it's another issue with transmission or inverter, it's covered under warranty given I replaced both less than a year ago. However I'm not sure and am worried that it's going to be $$$ in case it's something else that failed. Plus I'm getting serious doubts as to the safety of my car - what if I had been moving at a high speed on the highway during either of these situations?

Went to start the car up this morning - foot on brake and pressed the Power button. The car went through its checks but when it finished the 'Welcome to Prius' graphic it did a continuous beeep and displayed 'Check Hybrid System' and didn't start.
I turned it off and tried again and on the third or fourth attempt the car eventually fired up, the error message was gone and there were no warning lights on the dash. The car did smell like it was running rich though.
I turned it off and called the dealers. They said if no warning lights are now on it should be ok to drive the 6 miles to see them and they'll check it on their computer. As I drove to see them the car was running OK but the fuel economy was shocking. I was getting about 40 mpg UK (30 US mpg) as a trip average.

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.

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.

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.

The "Check Hybrid System" message came up on my dashboard. I took it to the dealer, and they said the temperature sensor on the transaxle was giving erratic readings. Unfortunately, they said that the only way to fix it is to replace the entire transaxle. They said I could keep driving it and that it would probably go into disabled mode before it caused any more damage. What I should do? It's a rebuilt 2012 Prius with 25k miles.

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.

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?

I have a 10 month (15,000 mile) Prius and the " check hybrid system" warning light came on while driving on the interstate. 17 miles later the car quit running. I had it towed to the local dealer and after taking a looking at it I was told the error code pointed to the water pump (which they plan to replace). Does that make since? Has this been a problem for the Prius IV?

Tonight I was driving my 2010 Type 2 Prius. I had been driving for about 6 miles in 85 degree heat (after the car was parked all day at work) on the freeway at 60mph when the "check hybrid system" warning came on and my speed reduced to about 40. I pulled over and called a tow truck. After I was towed to a dealer about 25 miles away, the car started up without the "check hybrid system" light coming on. However, the check engine light did come on. My car is low mileage with only 31,000 miles on it.

I was curious how you can get rid of an annoying "check hybrid system" dash warning?
Let's just say I know for certain nothing is wrong. It's only cause I accidentally disconnected and reconnected a wire. Just need to reset is all.

Went to the market, and my 2010 Prius II with 56K miles won't start.
Display works with the "Hybrid System Warning" message, but nothing else works.
