Prius (2004-09) :: ABS, VSC, Triangle And Parking Brake Lights On
Jan 26, 2016
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?

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.

Just 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 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

I was driving down the highway today and the brakes light (!), vsc, and master red triangle warning lights came on, along with a car with an ! in it on the main display screen. There is no noticeable difference in noise, mpg, or breaking performance. From reading through previous forums a bad 12v battery seems to be a common problem. Mine was replaced ~8 months ago. About 2 weeks ago the serpentine belt snapped and the car was drove ~2 miles to my home where I replaced it along with the bad water pump and also the thermostat. Could that have caused my current problem. 130k miles on the car...

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.

I replaced brake pads on my 05 Prius Monday. The instructions I have say to pull 2 relays and pump and hold the brake pedal until I hear a buzz. This has worked fine the last time I did the brakes. This time I got the Brake, Parking brake,VSC and ABS lights when I powered up.
I did not open the hydraulic system, just push in the pistons. I test drove it then touched the brakes. The left front and right rear rotor/drums were hot but the others were not. Long story short, I want to reset the ABS system.

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.

The battery in the back looks like it got smashed a little. Do you think this is the cause of the lights? It was a small suv so it missed the bumper and went straight into the battery area. Trunk wont latch anymore the it got pushed in.
Is there an electronic box back there that could have caused the lights to come on?

I have had the Prius for a little over 2 years now. Bought used and currently close to 150K miles on it and have put on about 25K miles a year.
This evening on way back home, when I turned on the Prius, I got the Red Triangle along with a bunch of other lights ON the dashboard.
Pressing the power button and everything would take much longer than usual - the lights(on the clock) was dim, the windows moved up and down rather slowly.
Eventually, i had to jump start and carefully drive home. Afraid it would stop somewhere at stop signs or long red lights, i constantly kept pumping the accelerator(not sure if that was good). Seems like need to replace the 12V battery.

Bought my daughter a used 05 prius. So far had had to repair the MFD, ac blower, 12v battery.
The engine light, red car light, the triangle light turned on. We replaced the 12v battery since we didn't know if it had ever been replaced. Drive the car for about 5 minutes, then all the red lights reappeared followed by not being able to accelerate. Immediately drove back home. First looked up the acceleration problem and it says to check engine coolant levels.
Low and behold the reservoir was empty. Purchased some, added it and drove around the neighborhood. The acceleration problem gone! Engine lights gone! Just as I am getting home, the dash lights disappear and the engine light only is lit, and red car on MFD. I drove it to our mechanic for error codes. It drove perfectly. As i go to turn off car, it wont turn off. It took another 5 minutes of power button holding, brake release and parking holding. It finally turns off.

2007 Prius 215,000 miles. Car has been a champ for the almost 2 years I've owned it, buying it with 150K miles. No real troubles and I've been driving it constantly as you can tell. Had an extended warranty repair done back in the winter when dash lights went out completely yet car would still start & run. Replaced 12V battery back them trying to diagnose trouble and it was original battery anyway. Daughter was driving when almost all dash lights came on including the red triangle. She came back home, turned it off. Next start was just red triangle and check engine light with red car on center display. Now it's just the check engine light and red car after sitting for an hour. I plan to take it in to get check engine light checked out.

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.

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?

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.

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?

I have a 2007 Prius 5 with 205,000 miles. Just recently, while Im driving the Red Triangle blinks on intermittently along with an annoying beeping. I took to dealer and they diagnosed error code C1300 which indicated that I needed a new "Brake actuator assembly with skid control ECU". I declined price tag because they said it's nothing critical (despite that it sounds rather important), and car will run fine without replacing this part. However, they said "nothing we can do about the intermittent red triangle and beeping".
Is this true? It's a very annoying noise. I know that it is possible to turn off the reverse beeping. Isn't there a fuse associated with "beeping" that could simply be disconnected?

I have several problems with my 2008 Prius that I will try to list below and I have done much of mechanic work myself but now I am a little stuck with some of the codes that are coming up and with some of the problems my Prius is experiencing:
Here are the codes that were scanned when I took car to a local parts store:
Coolant Temperature Sensor Evaporated Emission System (Vacuum Leak)
p3193
Accelerator Pedal Position Sensor
Pump Control Circuit Low
" High
I replaced the thermostat and now I get the red light displays on the dash anytime I go over 45 and the thermostat light on the panel displays there is a problem. I think there might be air in the system. Should I have a mechanic bleed air out or is there an easy procedure that I can do on my own to fix this problem?
I have also purchased a water coolant valve and this will be my next part to replace at 106.00 dollars. I am not sure this will fix my problem with my heat but I do not want to replace the heater motor because those run 630 dollars each.
Being that it is winter I want to fix the problem so that we can drive the car with some heat and not get the red light to come on intermittently. How to get to the root of these problems listed above?

I have been having some hybrid battery issues. My prius is a 2006 with 198,000 miles. The original battery was replaced at around 120,000 with a junkyard battery. About a year later that battery gave up the ghost and I decided to rebuild that battery. So far that has worked quite well until recently.
My troubles started a couple weeks ago when I got the Red triangle and all the dash lights and the hybrid system icon on the MFD. Naturally I thought it was the battery again. Took it out and checked the voltages of the modules. All the modules where within tolerances. I grabbed a OBDII scanner and checked the code. It was telling me that the Hybrid current sensor was bad. I changed that out with the wiring harness from the old battery.
That lasted for a few days before the red triangle came back. I checked the code and it was indicating one of the blocks was bad. I think P3019. So I took the battery back out and replaced that block with other modules. Almost instantaneously the red triangle came back with two more bad blocks. I think it was P3012 and P3022. So I took the battery out once more and tested all the voltages of all the modules. Everything was 7.86-7.9v. So I decided to start the rebalance of the existing modules in hopes to find some bad modules.
I also bought a new 12v battery and installed that. I got everything back together and took it for a road test. It took about 30 mins before the triangle came back. I grabbed the codes and it was still indicating bad blocks. P3011 and P3018. I am a little at a loss.
