Prius (2004-09) :: AC Stops Blowing Cool Air / Dash Lights Up With Numerous Warning Lights
I had just picked my kid up from school, as I turn out of the parking lot my A/C stops blowing cool air, I check the A/C screen and it still says it's set on High with temp at 68. However, it is blowing very low with warm air. Seconds later the dash lights up with numerous warning lights. I'm on the highway and I'm able to gather speed, but each time I do I hear the engine revving like crazy. We only live a few miles from the school so I am able to make it home. Once home, I turn off the car and turn it back on. The only warning lights displayed now are the red triangle and the yellow check engine light. I turn the car off, pop the hood, I check the belt and it was fine. I checked the oil and it seemed fine. I check the coolant overflow and it was empty.

Recently had an oil change. On the way home the ABS warning lights came on. Next day I realized cruise control didn't work. Today I realized battery is not charging/recharging when I apply brakes and tonight I realized energy monitor screen is not working.

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?

When I turned my Prius on today, the following warning lights remained on:
red "BRAKE"
yellow "ABS"
yellow "VSC"
yellow exclamation mark inside a circle inside parentheses.
It drives fine. After driving it a bit I tried turning the car off and back on a few times. The lights still remain on.
Prius (2004-09) :: All Warning Lights Go Off
Mine did. I was driving on the highway and pretty much every warning light went off. It was like the space shuttle crashing back to Earth. Freaked me out. Cruise control stopped working also. But I was able to get home safely.
So first, I tried AAA just to see if the guy would know something, but it was way over his head. He did notice my aux battery was failing, but not much else. Then I found a service online that comes to your place to do the work, and they sent a guy out on a Saturday and he read the codes, and did a full visual inspection, and yes, something was up with the cooling system. He suggested I have the dealer look at it because flushing the system is VERY important apparently. Should be done every 50,000 miles.
I was so worried it was the hybrid battery; we all know what that means! So I had the car towed to the dealer (don't drive if your Master/Hybrid light comes on!) and they said, indeed, the pump was gone. And, of course, they found a number of other things included the dying aux battery. It took them 4 days to get the damn part in stock. At least they covered the car rental for me.
Prius (2004-09) :: All Warning Lights Came On
The other night, went to start the prius and nothing happened except all the warning lights came on! So took the foot off the brake pedal and sat there for a minute trying to figure out. What the heck happened?? Tried a couple more times and then suddenly it was fine and it started! Now I have to mention that the outside temp was around 16*,,, not sure if that could have caused this strange reaction?

I have those 3 warning lights coming on after driving my 2008 Prius (60,500+) for approx 60+ minutes or more on a fairly warm day.
High 80's+.
I think that the heat buildup under the hood during a short stop is causing some component in the brake system to throw an error.
Prius (Gen 1) :: Warning Lights Illuminated - P3030 Came On
I recently purchased a 2001 Prius from a state fleet auction. The car has 121,000 miles and was in the non-running part of the auction. It had been sitting at least four months. I decided to give it a go since it looked to be in decent condition.
It did not start because of a dead 12v battery. I bought a replacement battery, but it still did not start. The screen showed ~ 1/8 hybrid battery. The warning lights illuminated and it was never ready. I plugged in my code scanner and a P3030 code came up.
I got it towed home and started working on it. The P3030 code signifies a high voltage line snapped .
Prius (Gen 2) :: Warning Lights With Codes Diagnosed
A few months back, my wife (2007 Prius) was telling me that she had some stuff going on with it. I found the diagnostic test for the 12 v battery and it failed. So I replaced the 12v and everything was fine until about two weeks ago. Two weeks ago, she got a check engine light. Then she stopped the car and when she fired back up again, the light was extinguished. So, I figured no big deal. Yesterday, she went to leave and the car was lit up like a Christmas tree. So she took my truck to work and left me a note about this. She figured I would drive my garage queen Vette... but I chose to drive the Prius to see if I could figure out some things, which I did.
Here is everything that I noticed thus far:
First, I will start with lights. Brake System Warning light is on, Check engine malfunction indicator is on, Red triangle with exclamation point Master warning light is on, VSC Vehicle stability control system warning light is on. Then on the tv screen panel, the Hybrid system warning light is on. I ran down to O'Reilly's to see what codes it pulled, and this is what I have: C0200 Right VSS, C0205 Left VSS, C1259 Regenerative Malfunction, C1310 Malfunction H/V System, P1121 Coolant flow control, X2 Valve Sensor Circuit stack, P0A80 Replace Hybrid Battery Pack, P3015 Battery Block 5 Becomes Weak, P3016 Battery Block 6 becomes weak, and then a few more repeats.
What I have looked at and what I have noticed/experienced thus far; At the beginning of the day yesterday, when stopped at a light, the engine would turn on and then shut off frequently (approx every 20 seconds). A lot more than normal. As of today, the engine just stays on constantly... even after the battery indicator shows full, it stays running. The battery cooling fan stays running. Sometimes the car lacks power at start out, When slowing down, I tried selecting the "B" as I know that it would normally work as a trans brake and regenerate power, it doesn't seem to be doing that and it seems as though the tranny doesn't know exactly what to do. I checked the 12v battery again through the diagnostic and it says it was at 12.2v so that should be good. I noticed that the battery indicator will show full and then just drop down to one bar and then go back up to full and stay at full for a while. Lastly, I saw the inverter check and I did that by turning the car on (ready on) and I can see the fluid moving around and I can feel it in the tube and the fluid level is good.
It sounds to me as if the ECM/ECU may be bad. Or maybe the HV battery. I was leaning towards the ECM/ECU just because of all of the different fluctuations, but with electrical stuff, it could very well be the battery.
Prius (Gen 2) :: Four Warning Lights Came On After Front Brake Job
Did a front brake job on my prius today. I replaced the pads and the rotors. I just turned the car on and I have 4 lights on : emergency brake, VSC, ABS and the yellow (!) warning sign. There is also a check engine, but it was there before (something related to my throttle pedal). I have a ODB2 device.
The only "special" things that I can think about is that we absent-mindedly pushed on the brake pedal while the caliper was off the rotor, so the piston was fully extended. Also, the lights were on for a while, so the 12V battery might be low.
We are currently charging the 12V battery.
Prius (Gen 1) :: 2001- Car Got Jumpy And Warning Lights Came On
I am having a problem which I can't pin down what it is. When I am driving my 2001 Prius, only after a turn, it seems to get real jumpy and the check engine light will come on during this. I know this is when it comes on because I unplug the starter battery to reset it several times. I've had it put on a computer and it gave a long list of things it could be up to and including replacing the entire gas tank assembly.
I've changed out the gas cap which was one of the things on the list, and I have a charcoal canister I got from the junkyard, but it's a pain to change, so if I don't have to change it, I really would like to not have to if it could be something else. I also put the highest grade of gas in it.
Prius (Gen 2) :: Battery At The Lowest Bar / Warning Lights Came On
Tonight I was driving home and the warning light came on. Thursday I was driving and noticed that the power lurched a few times. I switched over to see the energy usage and noticed that the battery was at the lowest bar. It stayed there for about 10 minutes. I called the dealer and started to head there. As I was talking the bars began to rise. It has seemed fine for the last few days until the lights came on tonight. I had just put gas in it. However, the car seems to run just fine and the traction battery seems to be charging just fine. There was no loss of power. Here in Texas it has been over 100 degrees for many days. I had an oil change at the dealer 10 days ago.

I bought my 2010 Prius IV Solar/Nav pkg in Febrary 2011. I've got just over 10k on the odometer. Aside from the persistent rattle/clatter/clank noise over bumps that these cars seem to be famous for, I've had no issues. That is, until last Thursday. The temps here in Indiana have dropped substantially so I was driving in town with the windows down, sunroof open. About two miles after leaving the office, I turned a corner and the car suddenly seemed like it went from running on 4cyl to running on 2 cyl. No warning lights came up on the dash, but the car was definitely shuddering/struggling to pick up speed, and was obviously running very rough. It felt worse when I was accelerating, but I think it may have even been doing it when I let off the accelerator.
This continued for approximately two or three blocks until I parked the car & powered down. After debating what to do (call a tow truck, confer with SafetyConnect, etc.) I decided to try & move the car again. Of course, it was as if nothing had happened. No warning lights were on & the car seemed to be performing normally. Since then, I've had no issues.
Prius (2001-03) :: Warning Lights With Exclamation Came On
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.

View 19 RepliesPrius (2010-12) :: Warning Lights Came On After Oil Change
Strange thing happened yesterday. After changing my oil as I left my friends house I had a couple weird indicator lights. ABS warning, the yellow indicator next to that ((!)) and the traction control light were all lit and solid. Brakes felt a little unusual. Less sensitive than normal but working fine....
I pulled out of his driveway, then went about 20 feet and pulled over. Shut the car completely off, turned it back on and all was normal.
The exclamation indicator was not lit nor Check engine and no messages were displayed. No beeping . It's almost like I had the car in some kind of brake test mode or something.
Here's what I did before I left his house:
While on jack stands I changed my oil. While it was still up on jacks I turned on the car to run the engine for a moment. (I put it in neutral to let it run for about 1 minute.) No leaks .. buttoned up the car, put it back on the ground. Filled oil to the top line and ran the engine again for maybe 30 seconds. Everything normal. Then I had it in "ON" mode while I checked my tire air pressure. (I had a warning indicator about that.) Once I had tires correct I put the car in ready mode. All indicators off and normal. Shut off car then had it in accessory for a little while. (Listening to radio) It was after this I left his house..... So I definitely cycled the car on and off several times.

I was driving at 60 mph and the master warning light came on. What may have caused this.
View 3 RepliesPrius (2004-09) :: Getting Some Warning Lights Intermittently?
Two days ago the first sign of a problem was the AC going out, followed by the red warning triangle and check engine lights coming on about 10 minutes later. Checked coolant and topped oil off (it is due for an oil change, btw) and drove about 20 miles home, no problems despite warning lights. Even the AC started working again. A little while after getting home, I started it up......no warning lights. I thought all was good.
Yesterday, no issues. Didn't drive more than about 15 miles though.
Today, took roughly a 25 mile roundtrip with no problems. Made the exact same roundtrip about 2 hours later and the red warning, VSC, brake system and check engine lights all came on (see pic) about 10 miles into the trip. I immediately turned AC off to remove that stress. No changes in car's behavior, however. Made it back home, turned car off and waited about 20 minutes. Turned it back on and only the red warning and check engine lights came on. 2 hours later....same two lights are still on.
Prius (Gen 2) :: Big Red Triangle And Yellow Warning Lights Showing Up
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.
