No reason, just came on this morning on the way to work. Driving at my lunch brake it 'fees' like the ABS and traction control isn't working...
I had a wheel sensor replaced 6 months ago when all the dashboard lights came on during a rainstorm.
Could this be another sensor...or maybe one that needs cleaning, going bad, etc.
I'm fairly handy with a wrench, but where to start?
i have the brake (!) the ABS and the VSC lit up after i got new bearings and new brake pads and rotors, the car was also stalling before the mechanic removed these bearing "dust cover" circles that must have been causing speed sensor interfernce bc the spedometer was stuck on 0....so the car seems to be done stalling after those were removed and all the big lights went off then i hit the brakes a few miles later and those three lights came on...
View 2 RepliesRecently 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 replaced 12 volt battery from a dealer nearby. Got it in OK, but my "!", ABS, and VSC and Brake lights are still on. Pads and shoes look fine. Is there a reset button or mode for these lights. I was under the impression that the display voltage test of 9 volts (dying battery) was causing the lights to come on. Just want to make sure there is no reset on the lights (like after an oil change) before I move on to other testing or the mechanic. The other symptom I've had along with these lights is the yellow arrows coming from the battery don't stop when I come to a stop. I have to put in neutral or park to get them to stop not matter how hard I press on the brake. This happened a couple years ago, along with the lights above, but went away. I wrote it off at the time to a bad connection somewhere.
View 13 RepliesI had the brakes on my 2004 Prius replaced. Recently the red Brake light and the orange ABS Brake lights come on some of the time - but not all of the time. I took the car in to my local repair shop. They said it would cost $300 to diagnose the problem.
View 19 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 have a 2004 Prius, with both the brake and reverse lights not working (right & left). Already replaced all bulbs and checked fuse...No luck.
View 3 RepliesI 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.
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.
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?
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.
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 parked my car (outside) and went on a business trip for three weeks. When I came back last week, when I turned the car on, the brake light and the ABS light were on. And it hasn't turned off since.
The car was working fine and didn't show any sign of troubles prior to me parking it, no funky light was on. What could be the cause? It wasn't driven during three weeks. What could have deteriorated to cause these lights to come on? The car seems to be braking fine.
FYI, before getting to my car last week, after leaving parked for three weeks, I mistakenly pressed the Panic button. And I didn't realize that the Panic button got stuck and was continuously in circuit. And it stayed like this for an hour before I realized what happened and fixed it. Not that I think that it can have an influence on my current problem, but thought I would mention it anyway...
I have a 2003 Toyota Prius, that you have to push sooo hard to make it stop, the ABS and brake light are on and there is some aweful chime that is solid and doesn't go away (very high pitch), I just got the car, and got it like this. I think its signs of a BRAKE BOOSTER, but I have been unable to loacted that, I found the Master Cylinder, but looks like you have to remove the Hybrid engine to do... Is there a procedure for this...

View 4 RepliesI have a 2009 Prius with 73,000.I turned on my Prius after a quick stop at a drug store today to find my brake light and ABS warning lights on. In addition, braking was rough. I have to step on the brake much soon and "deeper" to stop. After a quick search of the net I learned I wasn't alone. Here are the codes I received-
C1241- I just replaced my 12v battery about 1 1/2 years ago so I'm confused about 1241. I checked the levels. The are normal. The battery showed levels of 14 to 14.1v throughout the test. Maybe I don't understand the code?
C1247- Stroke Sensor
C1377- Capacitor malfunction
Before I take my car to Toyota, I would like your opinion on what actually works to correct the problem. I cleared the codes and the car works fine right now. If I continue to clear the codes will the car work? I searched the forum the one person seems to believe the to repair replacing Stroke sensor is the best/only fix.
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.
2005 with 110K miles. Had oil change about 2K miles ago, tires rotated about 1K miles ago. I was at a stop light when I felt a little movement in the brake pedal and the lights all came on. Brakes continued to work, but somewhat harder to push the pedal. When first applying the brakes, there was a very slight wandering of the car, which was easy to correct.
I drove the car home and turned it off. About an hour later I started it and the problem was gone. I took it to an independent garage the next day. Their scan tool found C1357 -- decrease pressure solenoid fault -- but could not go further into sub codes. They recommended that I take it to dealer.
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...
View 6 RepliesMy 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 was having intermittent problems with my cruise control but realized it would turn on and off if the wheel was turned 45 degrees. I replaced the spiral cable (with a Toyota OEM) and the cruise worked great! The only problem was that the VSC light was on. There was a fault for a steering wheel position sensor. I attempted to do a zero point calibration and now I have the red Brake, ((!)), ABS, and VSC lights on solid all the time.
I've unhooked the battery for hours several times, tried to clear the codes (no obd codes show up), and tired to clear the ABS fault by pressing the brakes 8 times in 4 seconds while in diagnositc mode and jumping 3 and 14 four times in 8 seconds.
