Prius (2004-09) :: Master Warning / Brake / ABS And VSC Lights All Come On
Title says it all. Occasionally when I try to start my 2007 Prius (70k miles), the master warning light along with the brake, ABS, and VSC warning lights all come on. I'll turn my car off and then turn it back on and it will start right away.
One thing that I notice is that it seems like the headlights and/or the MFD is dimmer than usual when this happens. I'll turn off the headlights, turn on the car, wait for it to start, and then turn on the headlights and everything will work correctly.
Prius (2004-09) :: Brake / ABS / VSC And Master Warning Lights Showing
Apparently my 2008 Prius decided to tell me in it's own way the same thing by showing me these lights this morning.
So they turned on while in a drive through, around the corner from my house. All except the master warning light. 5 minutes after the initial ones, the master light came on. And the braking power disappeared. I immediately got it home and shut it off..
After some research, I performed the 12V Aux battery test on screen in the car.
Confirmed -11.8v while ON, and 11.4 V when in ACCESSORY mode. So the 12v battery more than likely is the culprit for this problem.
Prius (2004-09) :: Master Warning / Airbag / Yellow Brake And VSC Lights Comes Up
My case involves a 2005 Prius with 55k miles on it with the problem of the master warning light (triangle with !), yellow brake light ( (!) ), airbag, and VSC lights coming on whilst driving. The car drives just perfectly fine without any discernible problems. Scan tool did not detect any codes. Tested the 12v auxiliary battery and it is strong with both voltage and amperage (even went as far as temporarily jury-rigging a fresh v12 battery in parallel with it to see if it would alleviate the problem). Inverter coolant pump runs well, coolant changed with appropriate Toyota Super Long Life coolant (50/50 mix) and system bled. Despite some drivers' concerns over disconnecting the 12v battery to reset the lights, this was done and the lights would go out, only to have them come on again after about 5-10 minutes of driving. Asides from the lights coming up, the car itself seems to be asymptomatic. Hybrid system appears to be running smooth and fine, SOC is good, asides from the lights the car drives very well.

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
Prius (2004-09) :: 2005 - Triangle Warning / Check Engine And Brake Lights Came On
My 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.
Prius (2004-09) :: Master Warning Light / Red Triangle Exclamation Point And Check Engine Light Came On
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.
Prius (2004-09) :: Master Warning / Tire Pressure / VSC Lights Came On
I was diving on the interstate and these lights came on and the car beeped. I checked the tire pressures and now the car will do nothing. It says a problem with park.
View 2 RepliesPrius (Gen 2) :: Won't Turn Off - Master Warning Triangle / Some Electrical Humming
This is the second time this has happened in the past few weeks. Each time at first start in the morning. Each time temperatures had been in the mid-20's (F) overnight.
Push start button and it seems as if electrical systems "sort of" come on -- there is a low hum of some sort, but the little light in the power button stays a dull orange and the Master Warning triangle as well as several other lights on the dashboard come on (Traction/VSI and some more, I don't remember).
Gas engine def. NOT running. I then hit power to turn off the car and nothing happens. Still "running" although really not, other than some electrical humming. Can't shift into anything (Reverse, Drive, etal).
Prius (2004-09) :: 2006 - VSC / Brake / Master Warning And Hybrid Light On
I just purchased this vehicle from a private owner, and the first day everything seemed fine. After a few days I get all these warning lights - Master Warning (Red Triangle !), VSC, and the Brake Light, plus the NAV screen shows the red car with ! in it. The car seems to run just fine though. I don't notice any performance issues. One thing I did notice when I purchased the vehicle, the previous owner had a batter charger in the trunk before he took it out.
Now I've check the batter using the LAN Monitor and it shows like 12.1 volts when I turned the car on (not started). I decided to give the batter a deep charge overnight (2 amp charge) after disconnecting NEG terminal from car. It cleared the codes for a little while, but then they came back. My ODB II tester shows no codes, only codes I found on the LAN Monitor was for NAVI - 01-e3 sub 00-5. Do I need to replace the 12v Battery?
Prius (2004-09) :: 2005 - Master Warning Light / Malfunction Indicator / VSC / Brake Warning Light Came On
In my one-owner purchased-new 2005 Prius w/ 74K miles and w/ no maintenance/accident history other than doing all scheduled maintenances at Toyota Dealers along w/ recalls applicable at each time (other than we had Toyota replace the 12V battery last year just because I knew it would die at some point anyway and I don't like pushing my luck; I'm not 100% certain if there's been a recall on any water pump for this car and if so, don't believe the dealer has mentioned it), I have the following indicators which appeared all at once while I was driving along at around 45 MPH in no unusual circumstances (80F, dry afternoon, about 30 minutes into a trip of mixed speeds, no loads in the vehicle, no effect on the car while driving):
From Left to Right on the display:
1) Red Triangle - Master Warning Light
2) Orange (Symbol)CHECK - Malfunction Indicator Lamp
3) Orange (!) - Brake Warning Light (but it didn't highlight the word 'Brake' in red)
4) Orange VSC - Vehicle Stability Control Warning Light
On the Screen:
Orange Car w/ the ! symbol - Hybrid System Warning Light
We immediately aimed for the house (about 5 miles away); the car drove perfectly fine, with the engine stopping and starting at lights as needed, with speeds going from the 55MPH we were traveling at the time of the alarms down to 0 and back up thru 35/45 MPH and such per normal off-interstate driving. The battery currently shows all the blue bars, and the engine and hybrid systems showed charge/discharge as usual as we drove. There was no discernible change in the driving reaction of the car to brake, steering, accelerator, etc.
Prius (2004-09) :: Master Warning, Check Engine, Yellow Brake Light Came On
2006 Prius with 164,000 miles.
First in the morning, starts fine, 500 feet later I'm turning out of neighborhood and I get lit up with:
Red triangle master light
Yellow brake warning (went away after I did signal check)
Check engine
Maint required light
The maintenance light is on because I'm 5,000 miles out of an oil change. I checked the stick, it did appear low, so I added a half quart of mobil 1 5w-30.
The inverter pump was changed due to recall in 2012, and I do still see turbulences in the fluid.
I have 3 pips of gasoline in the tank.
The 12V is a newly replaced yellowtop from elearnaid. Replaced about 1 year ago.
Prius (2004-09) :: Master And Temp Warning Lights Showing On Navigation Screen
Vehicle: 2009 Toyota Prius Base ... Recently my car started showing the master warning light along with the temp warning light on the navigation screen. After opening the hood and inspecting, there is a coolant leaking from somewhere. Took it to the dealer and was told there is no leak but a bad/blocked coolant tank assembly. Question is, if I bought the tank myself for under $1k, could I replace it myself? What would be involved besides replacing coolant? Do I need to get the air out of the lines? Etc.

for the last three days, I had the big red master warning light come up four times during normal braking, also "Problem" was displayed on the LCD where "Add fuel" is displayed when fuel is low. But no error code showed on the OBD reader. I searched found that it might be related to 12V battery which I replaced two years ago.

Prius (2004-09) :: Dash Displays Brake Warning And Red Triangle
We're on a road trip and the alarm tone goes off. The dash displays the brake warning and the red triangle (and the touchscreen has a car outline with an ! in the upper left). Also, the cruise control no longer operates. We return to El Paso and the dealer utilizes several hours and two diagnostics to tell us the Hybrid ECU needs to be replaced. Unfortunately, they can't get our Prius back to us until Monday, the day we are supposed to be back home starting work the next day.
We plan to call the other dealership in town in the morning. But is it safe to drive our Prius in this state? Can a regular garage make the repair? My father-in-law, an automotive repair professional back in Missouri, says that he isn't surprised if an ECU needs to be shipped from a Toyota distribution center since the part isn't regularly kept in stock by an auto repair shop.
Prius (2004-09) :: Won't Go Into Drive / Reverse - Big Red Triangle And Other Warning Lights
I have a 2005 Prius with 107K miles which I had taken off the road for about 2 months. Car ran fine previously. I just replaced the old 12v Battery with a new Optima replacement battery, changed the oil and filter, and have 1/3 tank of gas. Inserted the key into the slot, foot on brake, pressed the Power button, and, just about every warning indicator light is On (Brake, Red Triangle, Check Engine, (!), ABS, VSC, Traction Control) and the yellow exclamation mark with "Problem" message appears for a second on the Display, then a Red Car (!) appears in the upper left-hand corner of the display. Car will Not go into Drive or Reverse, and engine will not run, even when gas pedal depressed. Am I doing something wrong, or did I let the car sit too long?
View 11 RepliesPrius (2004-09) :: Triangle Warning And Check Engine Lights Went On
I 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 RepliesPrius (2004-09) :: Dash / Warning Lights - No Red Triangle Of Doom Shown
There's an ad for a car quite far away from me and one of the photos shows the dash lit up like a Christmas tree. Is this normal during power-up or is it normal when there's something quite wrong?! There is no red triangle of doom shown; I'm unsure if that might be out of shot though. Car is quite high mileage with just over 270,000 km on the clock and is from 2006.
View 2 RepliesPrius (2004-09) :: 2005 - Got Triangle Of Death And Other Warning Lights - HV Battery And Fan?
I own a 2005 Prius with 233K miles. I got the terrible red triangle of death and several other warning lights. Had the codes checked out at Toyota and confirmed a bad HV battery. I am kinda handy and I replaced it myself. No big job, it took about two hours, most of which was spent removing the interior panels, etc. Test drove the car and all looked well. Thirty or so miles later, BAMMM, lots of warning lights. At this point I took it to my mechanic to have it checked out. They found nothing you wouldn't expect when you've disconnected the two batteries.
They cleared the codes and off I went. Again about thirty miles out the lights went on again. Back to the garage once again. What they found was a corroded connector running to the fan, located under the rain gutter of the hatch, passenger side. Hmmm, how'd that get corroded?? Two years ago I remember drain the sump where the spare's located of 6 inches of water, how'd that get in there??? My mechanic confirmed he has seen that before in the Prius. So now I am wondering, did the initial battery fail because the fan may have failed??? Perhaps we need a warning light.....
Prius (2004-09) :: Yellow Brake, Malfunction, Hybrid System, Master Lights Came On
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.
