Yesterday on my morning commute, the red triangle, brake light and check engine light popped up on my dashboard. After about 10 more minutes of driving I lost a lot of my driving power. The system screen showed that there was no brake regenerating happening. I could hear the battery fan going behind me pretty loud.
View 7 RepliesI'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.
View 17 RepliesMy 2005 Prius with 116K on it has been having some uneven acceleration lately and today the Triangle warning light, the check engine light and the brake light came on at the same time. I had about 1/2 mile to go, so I proceeded slowly and called the dealership which had performed a routine oil chg two days ago. They said that if the lights weren't flashing then I could drive it. They recommended that I take it to AUTO ZONE and put it on the analyzer. This elicited these codes: P3019: no definition and P0A80: replace Hybrid Battery.
I have an appointment in 2 days and I'm wondering about a salvage HV battery since the car is 7 yrs old and over 116K miles.
I have a 2001 Prius with 210,000 miles. The inverter and traction battery were replaced last year. I started getting triangle and check engine lights about a month ago and the scan tool read p3191 p3006 p0300. The car would barely start in the mornings and the dash lights would be dim. I replaced the 12v aux battery today and all the symptoms went away. Driving home the triangle/check engine light popped on again and I stopped at Orielly's to use their scan tool. It now only reads P3006. I called a local mechanic who suggested to drive it a bit and clear the codes because the battery needed to equalize. Is this true?
View 8 RepliesI had just started driving this morning, when I a beeping sound came on and the Brake light, red triangle, and the check engine light came on at once, it is a 2006 Toyota Prius and it is my first car so I am still new to diagnosing the issue with my car.
View 8 RepliesWhen 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 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.....
View 17 RepliesI was driving last night and my car Triangle Warning Light and Check Engine Light Went on along with on the nav screen a car with a ! mark in it came on. On The info screen the battery level was changing fast from fully charged to just about empty. The car lost almost all power going about 42 miles an hour. I was able to pull to the side and i waited 10 minutes then tried to turn the car on again. I was able to drive home and the warning lights were still on but at least my car had power. What could possible be wrong?
View 19 RepliesSome days ago while I was driving, the check engine, red triangle and vsc lights came on and immediately my car slowed down. It would take longer to accelerate and every once in a while upon getting to a stop sign, it would take long to get to 5 from 0. could this be my hybrid battery going out? My regular scanner can't pull up any codes on a prius.
View 11 RepliesStopped at ATM when heard a thump under seat and all the above appeared on control panel. Waiting on computer code reader to test vehicle. Any clues to what all this means. Vehicle 2006 with 101K. Recent service as scheduled with coolant and inverter coolant and belt replacement done. No other issues to date with vehicle.
View 13 RepliesI was on my way to work this morning when the car just stopped accelerating (or so it felt), all the dash lights came on, I pulled over to the side of the freeway (I was very lucky). Radio and a/c were still working. Powered off, powered on too soon a couple of times - the red triangle and check engine both came on again. Cooled my jets and gave it a few minutes, powered on and the red triangle was gone, but the check engine was still on. Drives perfectly, no problems w/either gas or hybrid engine.
View 19 RepliesThis 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 was driving the car and triangle popped up and engine would not shut off while parked (key on) I hooked up the non prius aware scanner (carry one with me at all times) and don't remember the code, but it was a "HV malfunction".
I didn't shut the car off to clear the code as I was not home and attempted to drive it home, meanwhile engine never shut off. I had to come to a complete stop at a red light and the car died. tried restarting it but nothing. so I pushed it off to the side of the road and cleared the code. Tried again and nothing. didn't start, nothing. it beeped and error code popped up. Checked the code and it was p3125.
I know there are subcodes but online it was leading to inverter. but I replaced the inverter last year with a re involt. I had the car towed to my job for $50, to have it towed home, would cost roughly $168. When I got it to work, I did the screen thing and checked the 12v battery and it was reading 10.9 I have been meaning to get a new one for about a year now so I did.
I purchased a new optima battery and installed it yesterday, cleared the codes, tried to start it and nothing. error code p3125. What leads me to believe that it may be a transaxle, well actually a Mg2 is when my inverter went bad, it would start then shudder and die then the triangle would pop up. this time around, it doesn't even start. I have an appointment with the dealership to get the code with subcode read on Tuesday 10/15 for $98.7.
Our '09 generally gets short trips, though last weekend it had a long one. Last night it was fine my wife drove home from work, but when we tried to head out for the evening the check engine, VSC, ABS and brake lights all came on. Nothing funky on the MFD.
I ran the battery check procedure and the low value was 12.0 volts. The instructions here say it should be above 12, replace if below. Here we are on the edge?
My wife drove it to the dealer and complained that the brakes felt like they weren't working properly. Sounds like she had only hydraulic braking, no regen.
Recently there has been a series of problems popping up with the Prius. Its a 2003 model year.
- About four nights ago the warning icon and check engine light (picture below) popped up upon engine start-up and i noticed a weird idle. It seemed to idle rough. After about 20 seconds of idling the engine would shut off. After about 10 minutes and 6 or 7 attempts to restart the engine the warning lights disappeared and idle seemed to be restored.
- The afternoon after that the same warning icon and check engine light popped up along with the rough idle. After about 10 minutes and 6 or 7 attempts to restart the engine the warning lights disappeared and idle seemed to be restored.
- After this incident it seems like the vehicle is getting bad gas mileage. The picture below shows me getting an average of 25mpg. I was driving very conservatively. Driving the same way i usually do, i usually get 45-50mpg. The vehicle seems to be charging the battery more than usual.
Recently while pulling into the gas station the brake, Triangle !, ABS and VSC lights came on. The dealer reset the error and said my ECU needs replacement at a cost of $1843. The Prius is a 2005 with 147000 miles. No problems since the reset so I am hopefull. I don't recall reading about a lot of others having to have expensive ECU replacements so I wonder how many have had similar problems and replaced their ECU.
View 2 RepliesJust bought 04 prius. Anyhow fast forward to yesterday and I am driving home and notice the Brake light, (!), ABS, VCS lights come on. I read a couple forums about bridging pins 4,13 to get codes and this is what I have. (!)69, 57 ABS 42, VSC 45
I tested the battery and it was 13.8 V on and around 12.3 or something off. I felt around where the inverter pump is and it feels like there something going on in the middle hose. I tried to look in the reservoir but honestly I couldn't get it pumping when I had the hood up so I couldn't confirm movement in the reservoir.
I reset the codes (stomping on brakes 8 times) and it went away until I started driving home again today and they;re back. I added a file the is the sounds I hear when pressing the brakes. Truthfully I hear this all the time when I turn off the prius. I just noticed though that when I hit the brakes I hear it now. In the sound file you hear a pause when I press and release the brake pedals and reapply.
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?
View 1 RepliesWhat to check and do on my 07 Gen 2 Prius odo 109450 miles
My dashboard lights have the red triangle master hybrid /vsc and brake all on and I can still drive the vehicle.
I have been rechecking my repair work however after replacing the following parts
12v battery
inverter pump
coolant
traction battery
I am unsure how to troubleshoot my issue.
I replaced my rear brake shoes this past weekend. Immediately after I replaced them, the ABS, VSC, ((!)), and Parking Brake lights came on. I had not read that I should've disconnected the 12V battery before changing the shoes, so I wonder if that's related to the issue. I've read through as many threads here that I could dig up, but I still have questions. Here is what I know so far:
Car Info: 2004, 210k miles, Original 12V battery
Relevant Info: While replacing the shoes, one of the seals(?) (rubber part that slid over the piston(?)) slid off. I put it back on, and have checked for any fluids leaking, and have found none. I may pull the rotors off and check this again, though. There were no DTCs logged prior to the shoe replacement. Battery has shown no signs of dying, although I am going to check the voltage on it after I post this.
I tried jumping the pins, and I get the following flash codes (I tried resetting, but they came back immediately):
ABS: 4-2
VSC: 4-5
((!)): 6-5
I tried finding information on these flash codes, but have found nothing...
My CHS Tank was damaged in an accident a few years ago. I just replaced the CHS tank and the Inverter Coolant Pump within the last 12 months. It is still running when I power the car on and off as it should. I also jumped the fuse with a paperclip to double check that it runs.
My brake fluid levels are fine right now.
Possibly unrelated to the lights, but applying the parking brake is very easy. I don't think I adjusted the star adjuster enough. This is my first time messing with drum brakes, so it's possible I didn't adjust that correctly. Are these self-adjusting, or do I need to go back and adjust them by hand?
I have done some maintenance on a recently purchased 2004 Prius. Namely, replaced the inverter cooling pump, the right front wheel bearing and rear brake pads.
At a certain point, the brake, (!), VSC and ABS lights came on on the dashboard.
My wife is driving this car so I did not get the exact moment when the lights came on after my repair jobs.
I then replaced the 12V battery with a new one and reset the lights with the PIN 4-13 jumper on the OBDII connector. I did retrieved the error codes of each light and I googled them without any result and I now lost the paper where I had then written on
