Prius (Gen 1) :: 2001 - Triangle And Exclamation Warning Lights
Jul 15, 2010
I have a 2001 Prius with 150k on it. It has been giving me the triangle warning light and the car ! warning light. I can start the car and drive it, but sometimes when I press the accelerator the gas engine just dies and will not kick back in, unless I stop, turn off the car and restart it. (Issue seems to occur more in hot weather, could be a coincidence) When I start it the engine will run rough and shutter for less than a min, and then run normally.

All three warning lights went off yesterday just before hitting 130,000 miles. The warning lights consist of an exclamation point inside a triangle, check engine light, and what looks like a thermometer inside a car icon.

2001 with about 117,000. Just had it in to get the transaxle fluid replaced for preventative measure. Now I'm getting an intermittent triangle/exclamation warning. It seems to go off if I let it sit, mostly. Runs ok for the most part. But when that comes on, it practically limps on very little power.

So I was driving for a couple of hours today in my recently acquired 2001 Prius, when the red warning triangle and the check engine lights came on. The car seemed to still drive fine (70 ish mph cruising). HV Battery? P3000 P3020 Error codes.....

When i was driving my 2005 Toyota Prius the Red Triangle, the ((!)) light, the vsc light, and the check engine light came on. I let it sit for sixteen hours without driving it and everything went back to normal. Three days later i was driving and the same lights came on. I let it sit again for sixteen hours without driving and it was still there.
When i was driving i recognized there was a terrible lag, and if i was driving for awhile it took me about one minute to get up to 45 miles an hour. It felt like i was driving in first gear or something.
I also noticed if i had the Heating and air conditioning off that hot air would pump from my back right, which is the seat behind the passenger, that vent was blasting out hot air.
I took it in to toyota and they said the water pump was bad So they replaced it, after replacing it more codes came up and one of them told them to replace the Hybrid Battery Pack which is 3,419 dollars.
I Drove it out of there today thinking that some of the problem was fixed with the lagging of the acceleration and the heating coming from the vents but it was not. I was reading online and everything pointed to the inverter pump where the engine is not being properly cooled, which would explain the excessive heat and the lagging. They claim it still is the battery, but i was watching the battery on the dashboard navigation system and it seems to be driving and recharging fine.

So at about 147k miles, triangle comes on. It's the icon on the right with the car and exclam! mark through it. Turned off radio. listened to car and I could swear that it was running differently, but it might be in my head (I was kind of freaking). Drove to my Prius guy in the I.E. (20 miles) car seemed to act OK. Was using elec engine when needed and gas engine was fine. Was a bit shocked by how good the car was running but I was sure something sinister was happening and at any minute the car would melt. After 1.5 hours and a 20 mile test drive.

I've got a 2009 Prius with 67k miles on it. The car has a salvage title, but has given me over 20k+ worry free miles. The past few days the car has been acting a bit odd (i'm not sure if these are related or not but I figured I'd just throw it out there as well).... The right front headlight has been on the fritz as well as the wireless door opener has been working sparsely (sometime it wont lock, sometimes it will). I just ran the test to make sure teh 12V battery was okay, and all of the voltages came back in the "normal" range.

I currently have a 2008 Touring Package 6 with 180k and I am getting weird problems. I am getting the triangle of death, VSC, and yellow ! light. There is no check engine light. On the LCD I am getting the red battery + - icon as well as the car hybrid icon. I scanned it and I am getting a hybrid code P0A09 . All of the maintenance have been kept up and all fluids are perfect. No weird noises and the car is doing 53 mpg. It switches between gas and electric with no problems at all. Symptoms were yesterday with the lights. I cleared the codes and they would come back instantly. Today, I did the same thing and now everything is perfect. I am attaching the pictures of my dashboard lights that were on and the codes I was able to obtain in diagnostic mode.

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.

I am getting a 3006,3011,3015 code from my 2001 prius. The car only has 56k miles on it but sat for 8 months without starting or unplugging the batteries. I am wondering if i need to replace bank 1 and 5 on the battery to get the engine light off? The car runs fine and drives great but engine light is on and the triangle exclamation point is on but that's it for lights. What do i need to do? Replace battery altogether? recharge the effected banks?

I just acquired our second Prius, a beautiful 2002 (Gen1 in the USA) with 90k miles. On the dash, I get the red triangle of death with the exclamation point inside it. On the computer info screen, I have an icon of a car with an exclamation point in it and it reads "problem". I have connected the OBDII reader to it and it does not have any codes. Nothing in the history, or in the current or pending. The car has full power and runs fine, but has the stupid RTOD.

My wife's Prius now has the check engine light, the orange triangle, and the car with the exclamation point lit up. It only has 96,000 miles and hasn't been in a wreck that we know of. I've read that it has to do with the HV ECU, but I don't know much more about it. Is there any chance it's just a loose cable or something simple? It doesn't seem like her car should already be having so many extensive problems all at once. We haven't had any in the past, except the car with the exclamation point came on for a few days and then went away on its own.
Codes: P1636, P3106, P3002, P3006. It's a 2002 Prius

My wife and I own a 2006 Toyota Prius that we bought used 2 years ago. a couple of days ago, the master warning light (red triangle exclamation point) and check engine light came on. I took it into the dealer and of course, our hybrid battery was dead - battery and a new ECU required.
Our car is at 99,000 and 32 days out of warranty. Went down the road to atlanta hybrid repair. they were incredibly nice, and said that my computer was fine, but the battery would need to be replaced.

2014 Santa Fe Sport 2.0T FWD / 16,000 miles. All fluids full / up-to-date
On two occasions we've had a warning light appear that is not the CEL. It's a triangle with an exclamation point in the middle of it. The first time, my wife called and told me about it and it only appeared for a few minutes and disappeared. I checked the codes and there were none--that was several months ago.
The second time it happened (a few weeks ago), I was driving on an interstate at 70 mph with the cruise control on. The aforementioned indicator light appeared for about two minutes and disappeared. I immediately called Hyundai Bluelink (within a minute) and asked them to look at the code history and they advised they couldn't see any indication of malfunctions. They further advised that indicator meant that maintenance was needed and that I should make an appointment with the dealer. I pushed them for more info, but the operator remained vague about what maintenance my Santa Fe required.
Why does it only illuminate for a few minutes?

I bought this prius and it runs and drives great, no issues until a couple weeks into ownership and the car refused to "ready" up. i figured out real quick it was the 12v battery....BUT instead of replacing it i was trying to be cheap and charged it to verify for sure, worked great for about a week until it wouldn't start the car again and gave me the "park on level ground" warning. i got passed it after a few presses of the start button but the master warning, VSC, Brake (!), and airbag lights came on. I replaced the 12v promptly and this did not remove the lights. 2 weeks later the lights are still there and I have tried resetting the brake/airbag lights via pins 4 and 13 and failed at getting the lights to go out. a scan tool will delete them for about 10 seconds.
The codes I was able to pull via blink were:
(!) 11
ABS 42
VSC 51 45
airbag 23
I cleared them with the "press brakes 8 times" method, lights remain and codes pop up
VSC 51
airbag 55 57 23

Recently bought a 02 with 34 K, had been well maintained. Last night it wouldn't start so hubby jumped it (properly). Started right away, making him think that wasn't what it needed. Right after that, the Master Warning light came on, the Car with Exclamation Point in it (hybrid system warning light) and the check engine light. The car runs, but it did die, and I had to restart the car, then seemed to drive fine. We don't live near a Toyota dealer, would a regular mechanic be able to read the codes properly? What else should we consider? Should we drive the car?

I just noticed this morning that the "warning" light (orange triangle with exclamation point) is on in the Multi Info Display in the middle of the dash ONLY when the engine is off. I scrolled to it and it says "check charging system" with the battery logo. When i turn the engine on, the warning light goes away.
The battery logo does not light up where the gauges are. Does this mean the battery is okay? Its confusing and the manual does not clear it up.
Am I correct in assuming that I'm low on battery only if the battery logo lights up where the gauges are? I have no issues when starting the engine or anything.

Yes, they are all on. I have the red triangle, the check engine, the brake, and the vsc lights on. I put in a new high voltage battery this past summer so what now?

My daughter 03 Prius died on her, the codes it threw are listed as P3108, P3191,P3101. We cleaned MAF and throttle and this did not solve the problem. We replaced the MAF with a remanufactured unit from O'Reilly's and now the car drives normally, but the check engine and red exclamation light are still on.

My car (2006 Prius with 250k miles) was operating normally all day today. Still getting very good mileage around 52 mpg on average. Then abruptly, the big red triangle and few other yellow warning lights (check engine, VSC, and an indicator with exclamation mark in the middle) showed up while the car was moving around 20 mph.
Now, the car does not have much power and it was very difficult to speed up or going uphill. Turned the engine off and then back on. The symptoms still persist. The battery indicator was at only 1 bar. Let the engine run for a while and the battery indicator went to 3 or 4 bars. Turned the car off and then back on, the battery indicator went back to 1 bar immediately. Also the battery fan was running at high speed, even through I have just started driving for about 5 minutes.
Will do the following tomorrow:
(1) check 12v battery,
(2) use Torque SW to see if HV battery has proper values, and
(3) read diagnostic codes.

I'm not sure if this is a general FWD car problem or a Prius problem but a week ago I noticed a loud, and reasonably pure, tone that seems to be coming from the front of my '05 Prius at highway speed I don't believe it is tire, alignment, or road noise The car knows that something is wrong because it occationally throws some error lights but refuses to reveal the specific code My current thought is drive shaft, axle, CV joint, or similar but I don't know if that can turn on the error lights Any thoughts? Could I have two independent issues?
The car has 157k miles and was in two minor accidents before I got it One required a rear bumper replacement, the other they had to pop out a dent from the front driver's side quarter panel The records do not indicate that any other parts were damaged I have owned the car for 25k miles
Error lights: A few days after the noise started and 30 minutes into my morning commute while driving at highway speed up a hill (20kW from the ICE) I got the big red triangle of doom, ((!)), VSC, and the mark on the red car on the MFD. Aside from the lights the car appeared to drive normally I checked the voltage on the MFD less than a minute after the lights came on and it showed 14.1V The MIL light was not lit, and the Torque app on my android was not able to pull a DTC but was able to clear the error and consequently turn off the warning lights
The next day the same warning lights popped up again and at the end of the commute I used a paperclip to connect pin 4 and 13 on the OBD port in an attempt to read the code When I turned the car on with the two pins shorted the red triangle lit but the ABS, ((!)), and VSC lights all blinked at 2 Hz indicating their systems were normal After turning the car on and off four times the red triangle went away
The error lights have now popped up four times, each time after more than 30 minutes of driving I have also had several trips longer than an hour where the lights did not come on
