Prius (2001-03) :: Hybrid Warning With Check Engine Light On
Apr 1, 2011
I have a problem with my 2002 prius. I was driving home from work when all of a sudden my Hybrid Warning light came on with the check engine light on. On the screen, it gives me a (PS, Battery, and ! ) and the "!" was the one lighting up. The engine was roughing up sounds like it was gonna stop itself so I pulled over to the side and it turned off by itself without me doing anything except to put it on park. Then, i took out my keys and tried restarting it and all i heard was the "Ready" beep but not the engine and it won't move when i step on the pedal. After waiting for 10 mins., i tried restarting it and it worked i drove away and got home safely with all the warning lights i mentioned earlier still on. (Note: i was driving w/ the A/C on because it was hot outside..around 90s, also it was not overheating nor it was any battery problem because all the electrical were working properly.)

This afternoon, after driving about 150 miles, I came home and shut off my 2001 Prius. It was sitting for about 20 minutes before I turned it back on to drive off. Almost immediately, the hybrid warning light came on on the MFD, the red exclamation mark light illuminated, as well as the check engine light, and the motor shut off. I popped the hood, and could hear a high pitched squeal coming from near the inverter. I called my dealer to ask the service department what I should do, and they just told me to bring it in and they will take a look at it. I live over an hour away, so I don't want to bring it there if I can avoid it. I then shut it off and let it sit for a few hours.
After reading about the possibility of the auxiliary battery being bad, I went and turned the Prius on, and then shut it off several times to reset the hybrid warning light (I had to do so in order to access the aux battery information through the MFD). It turned on without incident, and shut off fine, and after being reset the hybrid warning light shut off, as well as the red triangle light. Then, I went through the process of pulling up the battery voltage information through the MFD.
With the car off, and the lights and fans off, the battery voltage read about 10.0-10.5 V. With the lights and fan on, the voltage dropped to about 9.5 V. After getting those readings, I drove it down the road a little ways, just going about 20 mph. It seemed to work fine. The check engine light is still illuminated. With the motor running, the voltage reading was 13.2 V, and then when I got back from my test drive and shut it off, the voltage hovered at 10.6 V with the lights and fan on.

Possible hybrid battery failure in my 2004 Prius (96K miles).
Sunday before last, the check engine light, warning triangle, and hybrid warning light came on when I started my car at the grocery store.
Because I was close to home, I drove home and the car functioned completely normally. The next morning, when I started the car, the same warning lights appeared. However, when I tried starting my car with the headlights off (I always leave them on), no warning lights appeared.
I took my car to an independent mechanic. This is their written report:
"Found multiple check engine codes, P3000, sub code 123, V0100 sub code 211/330. These codes are set when high voltage control detects a malfunction in battery pack/ECU assembly. To check battery pack we took vehicle out on a test drive while monitoring the cells in the battery pack. Found that they are all weak and drop fast when battery is put under a load. Code C2318 is a low voltage error/power supply malfunction code with the auxiliary battery. The voltage spec for setting the code is 9.3 volts, this battery is less than 9.2 volts."
In conversation, the mechanic also told me there was significant voltage variation across the cells in the hybrid battery.
I then took my car to the dealer to try to confirm this analysis. They were unable to read any codes because the independent shop apparently cleared them. The dealer was unable/unwilling to do more than read the codes to diagnose the problem. (Indeed, they seemed surprised that the independent mechanic could monitor the cells in the pack.) All they did was to drive the car around some more to see if the check engine light would come on. It did not.
The car has been driven 80 miles since the warning lights last appeared and appears to be behaving normally. From your perspective, does the report from the independent mechanic make sense and is it believable? And is their test under load definitive of a hybrid battery problem? Could the results be affected by the low auxiliary battery? Also, if I do have a hybrid battery problem, what are the chances of being suddenly thrown into limp mode while driving 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?

I have a 2005 Prius with around 115,000 miles.
I have the following warning lights on:
1) Check Engine
2) Yellow Indicator, looks like exclamation point inside a circle inside parenthesis.
3) Red Multi-information display (exclamation point inside a triangle)
4) Hybrid System Warning Light on display screen, looks like exclamation point through a car
The engine cranks up just fine and drives forward and backward in the driveway fine. Battery level indicator is blue (see image). I checked for turbulence in the inverter reservoir with the engine off and fluid was flowing.
I checked the 12V battery (using the car's measurements by holding Display and turning lights on and off 3 times) and its value was 12.1 volts without engine and A/C on and 11.8 volts with them on.
The fan in the back right passenger seat is always on now though (I don't remember ever hearing this fan noise before), regardless of engine on or not, even though it's only about 80 degrees outside and it's been sitting idle all day and all last night. It comes on pretty much immediately when the power button is pushed.

About a year ago when driving on a 3ish hour trip, I made it almost to my destination and the hybrid warning lights came on. I noticed my windshield wipers were moving extremely slowly, and about five minutes later the screen and all the lights flickered off, the power steering went out, and I came to a dead stop on the side of the road. After calling a friend to come rescue me, they arrived and for fun I attempted to start my car and it ran fine, and the next time I drove it all the lights were off. I drove it for several months afterwards with no problem. It happened again a few months later and I took it to the dealer who "completely disassembled" my car and said they found nothing wrong with it.

I have a 2003 Prius with just over 116,000 miles. When my wife cranked it a couple of days ago, the "Hybrid System Warning Light" came on.
As advised by the owner's manual, we didn't drive the car. We took it to the local dealership to be checked out. When I called for an update last night, they said that the computer indicates that the hybrid battery is leaking.
So I guess my questions are:
1) What kind of lifespan is typical of a 1st Gen Prius?
2) How many more miles are reasonable to expect from the gas engine?
3) Is there anything I should be aware of to make sure I'm not taken advantage of? (eg is there a credit for the battery since it has valuable components)

I was on my way home (a 50 mile trip on very rural roads) when my hybrid warning light came on. The car seemed to be operating fine, so I continued on. About 20 miles from home, the computer display lights flashed on and off and the car died. After coasting to a stop, I let it sit for a couple of minutes and turned it back on, and continued on. Warning light was still on. Probably ran about 7 miles or so and died again. This same scenario happened a couple more times, but I did manage to get home.
My Prius is a 2002 with a little under 150000 miles on it, and it has never given me any problems since I bought it at 70,000 miles four years ago. I will be calling the Toyota dealer tomorrow, but I wanted to ask whether or not this sounds like a possible battery pack failure.

My wife has a '03 that has been great. No issues. I am a excellent mechanic, on conventional cars and motors. Here's my story:
Bought the car used and working last week. Put in a new 12v Group 26 battery w/conversion. I verified the 12v battery was at 12.8v and when engine was running, 13.6v to charge the battery. Car was starting and driving wonderful for about 600 miles. No shuttering, no shaky starts. Mileage was about 38.6. Anyway, yesterday was driving and all of a sudden the warning Triangle comes on, Hybrid system icon comes up and the engine goes off. I was able to drive the car about 1/2 mile on the traction battery back to my work.
It happened to have a code reader handy and it reads a P3125, Inverter. I realize there are sub codes that further diagnose the issue, but I don't have that type of OBDII reader although mine is a very expensive model. Anyway, I reset the code and got the car to start. Motor begins to go up in RPM and throws the code again. I shut it off, reset the code, try to start the car and I feel it slightly jump forward, engine does not start, then throws the warning code again. I did notice the traction battery is at 25%. I do this two more times trying to get the engine to start before I call the tow company. BTW, the car rolled easy, so I don't think its the MG2 is bad, although correct me if i'm wrong but doesn't Mg1 start the engine?
Oh, incidentally, also the ignition key does not release either. The key release solenoid is energized unless I unplug the 12v battery, then I can get my key out.

I just switched out my hybrid battery and put in a brand new one. Now, the car isn't doing anything and all that's on is the check engine light. What now? I was told I had to tow it to Toyota and have them reset the computer. Sound right?

My check engine light came on, I took the car to my usual mechanic, and he said the codes returned indicated that two cells in the batter were bad. (I just called to get the codes, but he's out of the office for about 30 minutes on a test drive...)

The engine check light is ON this morning. It said that there are problems for the hybrid system on the display. I sent it to dealer immediately.

So this morning when i started up my car the cel came on. The car seems to be running fine so i decided id try to go to work and hope for the best. Well nothing happened and i made it to work fine, but i noticed i was always regenerating power. My drive is 45 miles all freeway and little traffic most the drive.. ive never had this happen on my drive to work and ive had the car for a year now. Could the hybrid battery be dying? i have a cheap scan tool but that doesnt mean i will get the correct reading...

I own a 2005 prius. It is stock and i recently had the check engine light pop up as well as "problem" when car was started and 2 lights with exclamation point, one on a car and ones in lil brackets. I believe it is called a "hybrid malfunction light". Well one day they all pop up and about 3 days later theyre gone. Only thing i did was fill up the tank, when they came on only 1 bar was left on the tank. My question is should i still take it in to see whats wrong with it? and what could of caused both lights to come on?

Gen3 Prius. Once it turned 100k miles I took it in for an inverter coolant change per the maintenance schedule. The dealer charged $109 for this and the car had absolutely no issues prior. Got the coolant changed on 7/23 and then drove it short distances in town for two weeks with no issues. Once I drove it on weekend longer road trip got a check engine light P0A93 "inverter A cooling system performance". Shortly there after started getting hybrid overheat alerts and pulled over to let it cool.
I checked the inverter coolant reservoir and it was still above full. After letting things cool, I turned it back on and listened to the water pump. Seemed to be running fine, heard it clearly with my ear up to a long screw driver, touching the pump. Noticed that the hose leading to the pump was vibrating but the return hose out of the inverted was not. Also no turbulence in the reservoir. My guess is that they didn't bleed air out of the system.

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.

I was going through a bad day today with my 2010 Prius Gen 3. I was on highway driving at 68MPH behind another car, at the time I step down on gas pedal for overtaking, all a sudden both "Check PCS system" and "Check Hybrid system" appears on the Console display and gas pedal had no response from the engine at all. The car was not moving and I had to stop aside and "P" the car. I tried to turn off the car, turn back on more than 10 times. Both warning signal "Check PCS system" and "Check Hybrid system" display on console and the car can not go into "ready" mode hence the car can not drive. I could put shift to "P","N" but just not "D". Had to call tow truck to tow back to toyota dealer, and they said will look into it on Monday.

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.
