Prius (2004-09) :: Transaxle Disengaging / Hybrid System And ABS Warning Lights
Jul 11, 2012
I have a 2005, I purchased new in 2005. I now have around 120,000 miles and have had no problems - just oil changes and new tires.
I was driving on the interstate in MS and all of a sudden all these lights come on on my dash including the triangle that means take it to your dealer immediately. The car sounded funny acted funny and accelerated funny. I was closer to home so I came home and called the dealer. They said to drive it in but if it started acting up to pull over and they would come get me.
When I cranked it, it sounded like I was pushing the accelerator but I wasn't so I cut it off then cranked it again. I drove it very slowly cause it was acting weird.
I drove it home to discuss it with my husband and to do some on-line research here. So 2 - 3 weeks later my husband decides to look at it and by now the little battery is dead - it is the original battery too -btw. So I bought a new toyota battery (the little one). My husband hooked it up to see if the car would crank. It did but all the lights on the dash lite up again including a couple new ones!

Car was deemed a total loss. I didn't think the damage was too bad and one of my friends at a bodyshop told me to go ahead and do a car buy back that I can't go wrong with a prius. My mother said $20 gas a week. So I did and gave my mom the difference. The Car drives going forward and in reverse just find. Besides the body damage I got underneath the car and I see a bent tie rod end and maybe a lower control arm. The thing is when I hop inside to move the car I notice the car reads transaxle disengaged and battery system won't charge in neutral.

I seem to have gotten a hum coming from the front end when I reach 40mph & higher. Todate, I have not gotten any warning lights, red trinagle etc, but wanted to see if maybe there were some codes thrown.
Lastnight, I put the front on jack stands & had my wife put the car in D & step on the gas while I was laying under the car. The noise is coming from the transmission where the axles plugin. My fear is I need a new tranny.....but if its a code related to the hybird system, I might be covered under warranty.
By the way, my Prius is a 06 w/ 108xxx miles. I changed the CVT fluid around 70xxx miles.

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?

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.

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.

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?

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?

I have a 2005 Prius with 135k miles. Yesterday the red exclamation light came on and also the hybrid system warning light. I shut the car off and it came on again. The third time the car started normally and it is driving normally today with no warnings. Does this sound like the 12 volt battery? It is original.

During a highway trip three months ago, my 2004 Prius suddenly lost engine power, the red triangle Master Warning light came on accompanied by a warning sound, and then the Hybrid System Warning sign appeared on the Multifunction Display. I pulled off to the side of the road and stopped. I turned the car off and then tried turning it on again. Engine power was restored although the warning lights remained. We took a chance and carried on with our trip. The same sequence of events reoccurred about 10 times on our 1,300 km journey. I took the car to a Toyota dealer where they found a C2318 DTC. They checked the battery and the HEV fuse but could not locate the problem.
We returned home and on the way the same thing happened a few more times. My service manual noted that the description for C2318 is Low Voltage Error (Power Supply Malfunction) and the trouble areas are HEV fuse, IGCT relay, Wire harness or connector, or Auxiliary battery. Since the car was nearly 7 years old I thought I had nothing to lose by replacing the battery, which I did. However, on a short 150 km trip last week the problem appeared again, once while approaching our destination and once when we were almost home. There seems to be a pattern in that the problem appears every 150 km or so of highway driving. It has never done it while driving in the city.

A few days ago I was driving my 2005 Prius aggressively up a mountain road and all at once the hybrid system warning light, the triangle with the exclamation point, and the regenerative brake system warning lights came on.
After about 2 minutes parked, I restarted the car and the regenerative brake system warning light went off, but the other two were still on. I still drove it twenty miles home, over another substantial mountain gap (about 1000 ft up and another 1500 down), without any problems.
I checked the voltage of the 12v battery, which seemed to be on the low end, but OK. (I think the lowest reading was 11.9). There seemed also to be some turbulence in the inverter coolant reservoir.
I brought it into the electronic vehicle specialist in town here today, who pulled my codes and said that the hybrid battery was dead.

I haven’t been on these boards very often since getting my used 2008 Prius because until now it has been very kind to me in terms of not needing mechanical repairs. Unfortunately that good streak seems to have come to an end. Driving home Monday evening (after ~30min freeway driving), my master system warning light came on, accompanied by the hybrid system warning light. I didn’t know what the latter was – had to look it up – but I immediately pulled to the shoulder. The car was driving normally, however. Since shops and dealers were closed for the evening, after much debate I ended up having the car towed to a family friend’s body shop; they were still there and had a scanner to check the error codes for me. My car was on the side of the freeway for well over an hour with hazard lights on and the dome light on and off occasionally as we got in and out of the car. By the time the tow truck arrived, I discovered that the 12V battery seemed dead; car wouldn’t boot up all the way, wouldn’t shift to neutral and didn’t want to power down – I had to try turning it off upwards of 10 times. I was surprised, given just the hazard light and limited dome light usage. We jumped it, got it in neutral and on the truck.
At the body shop, they said there were no error codes related to the hybrid battery; something about transmission that wasn’t clarified, and errors for low voltage on the 12V battery. With everything off, it measured 10-something V; something higher when turned on, but they believed the problem was a dead 12V battery. I was surprised that it would suddenly give out in the middle of driving, but we went ahead and replaced it the next day. I picked up the car Tues evening, and had no problems driving it home, to work the next morning. Unfortunately, during my drive home – strangely at almost exactly the same location as the first time – the same hybrid system warning light came back on. I’d driving about 70 miles with it off at this point before the reappearance. This time I didn’t pull over to the side (had enough of that before) but rather drove a few more miles to a parking lot where the car has now stayed overnight. I note that the car seemed to drive perfectly normally during that time; no loss of power.

I have had no issues with this car of 120K miles until today, although my MPG has decreased to 35 MPG. The following lights came on with a loud beeping sound : Brake warning lights, malfunction indicator light, master warning light and the hybrid system warning light. These stayed on for 25 minutes and then went off. I drove 12 miles without any issues with all the lights and sounds beeping.

A year and a half ago, I had the hybrid battery warning lights come on and had it towed to the dealer. After given the option of replacing the battery for $4300, I took it home and did a single cell replacement (all cells ~8V, one at 6.6V which I replaced), which seemed to be all good until yesterday. Back with the warning lights and blower fan, I jumped to the conclusion that I have a similar situation, removed the battery and all cells are 8.04V +/- .05V except for 1 cell at 7.92. I am not convinced that this cell is really the culprit.

I have been having some hybrid battery issues. My prius is a 2006 with 198,000 miles. The original battery was replaced at around 120,000 with a junkyard battery. About a year later that battery gave up the ghost and I decided to rebuild that battery. So far that has worked quite well until recently.
My troubles started a couple weeks ago when I got the Red triangle and all the dash lights and the hybrid system icon on the MFD. Naturally I thought it was the battery again. Took it out and checked the voltages of the modules. All the modules where within tolerances. I grabbed a OBDII scanner and checked the code. It was telling me that the Hybrid current sensor was bad. I changed that out with the wiring harness from the old battery.
That lasted for a few days before the red triangle came back. I checked the code and it was indicating one of the blocks was bad. I think P3019. So I took the battery back out and replaced that block with other modules. Almost instantaneously the red triangle came back with two more bad blocks. I think it was P3012 and P3022. So I took the battery out once more and tested all the voltages of all the modules. Everything was 7.86-7.9v. So I decided to start the rebalance of the existing modules in hopes to find some bad modules.
I also bought a new 12v battery and installed that. I got everything back together and took it for a road test. It took about 30 mins before the triangle came back. I grabbed the codes and it was still indicating bad blocks. P3011 and P3018. I am a little at a loss.

My 2004 Prius Transaxle overheats and causes a warning on the dash. When I checked the fluid level I found pink foam in the resevior. Do I need to replace the fluid or bleed the system. Also the AC shuts down when this condition occurs.

I just wanted to share my story here. Last week on a routine trip on I-5 warning lights started flashing indicating hybrid drive failure. The car automatically shifted into neutral and I was limping along down hill. Luckily I saw a downhill exit and had the foresight to turn off where to my horror I discovered that my brakes didn't work. So I had to coast to the bottom of the hill and again made a quick decision to turn into a slight uphill side street to force myself to a stop with the parking brake. At point the car completely died and I couldn't even shift into neutral to push it.
After towing it to AAA and avoiding a collision on I-5 (if I pulled into the shoulder without breaks I likely would have crashed into a retaining wall) and then not being smacked after I got it to a stop I was pretty shaken...I'm lucky to be alive.

I've got some issues with my 2005 Toyata Prius (~150,000 miles). My wife was driving recently and the "Master Warning Light", the "Hybrid System Warning Light" and the yellow "Brake System Warning Light" all came on.
Some quick reading of the owners manual said we should take it to a dealer right away, but because it was a yellow, and not red, brake system warning light it seems ok to drive at least to a dealer. in regard to the yellow brake system light the manual said it could be that: "the regenerative brake system failed or that the hydraulic brake system failed".
Now, I have a cheap bluetooth OBD reader hooked up to the "torque" app on my phone and I thought I would try to see what error codes there were to learn more. But strangely, it did not read any fault codes. I've used this reader successfully on my 2001 Mitsubishi galant, but I'm not reading anything for the prius in this case. I'm not sure if there is legitimately no error code associate with the warning lights or if my app is just failing to read them for some reason.

I have a 2006 prius I got used and in good condition about 3-4 years ago. I never had any problems until a cop pulled me over and it turned out my parents had decided not to notify me they hadn't renewed my registration and my insurance they've been paying had ran out. I've since learned my lesson on keeping up with the dates.
I "luckily" got to go home with just some tickets. It sat about 2-3 months until I could get the money to line everything out. I ran it at least once a week but apparently that wasn't enough? Now that everything's up to date I started driving it and the yellow circle with the (!) in it is on. The Master system light, the check malfunction light, and the hybrid system light is on.
It seems like it applies the brake when I'm driving constantly now. It stalls when I first try to speed up. And the fan? on the passenger side of the back seat is always running for some reason. I tested my battery volt and it's at 9.2.
I took it to an auto shop today in town. I live in WV in the backwoods. And they wouldn't hook it up to check for codes and referred me to a dealer about 30 min. away... I've never had any problems with this car before.

I was trying to install the invisicord cable for my escort radar detector thru the auto dimming/homelink mirror, I shorted it and homelink no longer has any power, a couple minutes later i got a check hybrid system.
Now question how do i restore power to the homelink mirror, is there a fuse to replace? And that warning and all the other warnings that i got related to the short. I read somewhere here that if power to the homelink mirror was off that you get no power to some systems, not sure where is that post, cant find it the car starts.
