Prius (Gen 1) :: 2003 - ABS Warning And Brake Light Came On With Alarm
Apr 22, 2014
So the 2003 ABS warning and Brake Light came on the other day with the alarm. The alarm cleared after a few minutes and the first time the warning lights cleared. I drove the car around town to see if I could replicate the issue. No issues found. My daughter drove the car for a few days and after work one night she called to say the lights and alarm were back on her way home from work.
I am not sure of her braking habits whether she presses evenly or if she jabs the brakes. I put the car in my shop today and after it ran for a few minutes the alarm cleared. The lights remain. What I would really like to get my hands on is a dvd copy or soft copy of the repair manuals so I can review the troubleshooting steps to determine what my next steps are in determining if there is a bad component. I have not changed brakes nor added fluid to the car since just after I bought it two years ago.

I'm getting this warning light coming up frequently - it's the same light that appears when I engage the foot brake.
Does this mean something thing is about to catastrophically fail?

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.

I've got some issues with my 2005 Toyata Prius (~150,000 miles). My wife was driving recently and the "Master Warning Light", the "Hybrid System Warning Light" and the yellow "Brake System Warning Light" all came on.
Some quick reading of the owners manual said we should take it to a dealer right away, but because it was a yellow, and not red, brake system warning light it seems ok to drive at least to a dealer. in regard to the yellow brake system light the manual said it could be that: "the regenerative brake system failed or that the hydraulic brake system failed".
Now, I have a cheap bluetooth OBD reader hooked up to the "torque" app on my phone and I thought I would try to see what error codes there were to learn more. But strangely, it did not read any fault codes. I've used this reader successfully on my 2001 Mitsubishi galant, but I'm not reading anything for the prius in this case. I'm not sure if there is legitimately no error code associate with the warning lights or if my app is just failing to read them for some reason.

Two days ago my '03 Silverado stopped recognizing when I pop the parking brake loose and now dings incessantly while I drive and the parking brake light on the dash flashes on and off.
I tried...
1.) Engaging and releasing the parking brake multiple times.
2.) Checked the brake fluid level (perfect level)
3.) Checked my owner's manual (not enough info in the manual)

Last night I was driving my '99 Passat when suddenly I heard this loud alarm in my car. Quickly looking down I saw what I think were my ABS and brake indicator lights on. It happened so fast, maybe less than a second and everything was back to normal.
I was driving on dry pavement on country roads at about 60 mph. Outside temp was 37 and there were major gusts of wind, maybe 40 mph or so. Vehicle has about 115,000 miles on it.
Checked my manual and it said to have it checked.

We recently purchased a used 2006 Prius. The vehicle has approximately 74K on it now. Well the other day my wife went to leave work and pressed the power button while pressing the brake pedal, and the Master Warning Light and brake warning light both came on. The car would not allow her to shift the car so she tried to turn it off and it wouldn't do that either. After about 5 minutes she finally got the car to turn off, and when she restarted the sequence everything went back to normal and she drove home fine.
We called 2 dealers and they both seem to be confused by the symptoms, but one thought that maybe the battery was old on the transmitter. So thinking that might make sense I replaced the battery with a new one.

I have recently had an issue with the brake warning light coming for 15 seconds or so after navigating a freeway cloverleaf etc. It doesn't come on under any other circumstances. Of course, this sounds like a low brake fluid issue (fluid moves to one side of the reservoir in the corner, causing the sensor to report the fluid is low). However, I have checked the fluid level in the reservoir, and it is very near the full line. I see no external evidence of leakage anywhere (not surprising since the fluid level in the reservoir isn't low), and the brakes work exactly as they always have.
I know the brake light can indicate problems with the traction battery (brand new, in my case), but that doesn't seem to be likely considering the consistently intermittent nature of the warning light illumination. Does the brake warning light monitor anything else other than certain traction battery issues, brake fluid level, and the parking light being on? Is the sensor for the brake fluid level a simple float like I have seen on other vehicles?

While coming home tonight in a snow/ice storm I got stuck in a drift at the end of our driveway. After some shoveling we got out, but there was some spinning tires before we got enough traction to go. A short time later when we opened the car door there was a warning sound and, after starting the car, the brake/abs warning lights came on.

Purchased the car several months ago and have done all maintenance and the car is overall flawless but I believe it to contain the original 12V battery.

I charged the almost dead 12v with a slow charger and it is fine now. but immediately after charging the brake system light came on. I believe brakes are just fine, and want to reset the light and see if it will ever give again.

2001 Prius, 182,000 miles... Master Warning Light and brake light came on.....
I took it to the local dealer and they did a diagnostic, and they pulled the codes P0300, P3125, P0301, P0302, P0420, P3006, P3016, P3017. They said I would need to replace the the hybrid battery, the inverter, the catalytic converter, and the spark plugs.

At just about 21800 miles and 19 months service this morning the brake system warning light came on. This is the yellow brake system warning light, not the red brake warning light or the generally similar looking yellow low tire pressure warning light. No other warning lights are on in the service indicator panel. What troubleshooting can I do myself before taking it to service facility?

I have a 2003 V8 4WD SR5. It has 109K miles and I replaced the pads and rotors and front calipers about 8-10K ago. Since then it has been doing fine in the brake department.
This morning, the brake warning light (the parking brake light) came on about half illuminated. The parking brake is not on and when I press the parking brake it illuminates fully. The other warning lights associated with the brake system (VSC TRAC OFF, VSC OFF, and ABS) are not illuminated. The fluid is at the max line, if not a bit above.
Given this info, I don't believe there is a major problem or else it would actually be fully illuminated and the other lights would be on as a result of the brake light. I am just curious what is causing this issue and how to fix it.

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?

2010 Prius V owner as of last week. All has been going well and got into the car this morning and all of the above noted lights are on at start-up and stay on as I drive. Have made appointment with the dealer but they cannot get me in until late next week. I did make a short drive this morning and all seemed fine with handling and braking. Searched a few threads here and answers are very varied and none that I saw had all of above lights on. I don't think that it is the Hill Start Assist. Safe to drive until we can get into the dealership?

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.
