Prius (2001-03) :: Brake / ABS Light And Buzzer Come On For 5 To 10 Seconds Then Go Off
Aug 25, 2015
I'm also having an issue with these lights/buzzer on my 2002 since last weekend. Probably about one in every five starts, the brake/ABS warning lights/buzzer come on for around five to ten seconds and then go off. Braking appears to be fine. I'm thinking the brake system is taking too long to pressurize on starting. The car has run fine and brakes have worked fine after this has happened. Brake fluid level is fine. Do these warning lights/buzzer usually stay on, with an issue, or is this intermittent lights upon starting how it normally shows a problem? And yes, I am going to see about finally ordering a mini VCI and also read the blink codes. Dealer is 50 miles from home so I'm trying to figure out what is going on prior to heading that way, as I don't want to have an issue on the drive there.

My wife's 1998 Passat's ABS and Brake lights both comes on along with that beeping buzzer. Everything is norm from start up, but after driving about 10 miles or so the ABS/brake light& buzzer show starts up.
It seems the ABS is working because my wife found a patch of sand in a parking lot and jammed on the brakes while the ABS/brake light& buzzer show was going on. She said she could feel the brakes pumping.
We took it in to the dealer and they check the brake pads and sensors. They said that the sensors and pads were ok. They thought it might have been dirty sensor, so they clean them.
Two days later the ABS/brake light& buzzer show came back. But this time my brakes squeal a little if you press on the brake lightly. (cleaning solution got on the brakes?) Also how big a deal is it installing a new ABS black box ? (where is it?)

I've replaced rusted out brake lines on my 1998 GMC Sierra 1500. I bled the system properly and every thing seems to run fine and brakes good. But the brake warning light stays on in the dash and buzzer is on. What to do to turn these off...

OUr 2005 Prius has been intermittently popping on the buzzer/ ABS/ VSC and BRAKE lighte, usually when the brake pedal is touched, but sometimes without any apparent initiator. It remains on usually for 10-20 seconds, but occasionally stay on 20+ minutes. Interestingly, often, when the turn signal is activated, it immediately goes off. Dealer says there are no scanned error messages (and of course charged us to tell us that...), and to bring it in "while the lights are on." Right. It sounds like a short somewhere, but I don't know where to go from here.

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?

I just bought a prius 2007.
I have a unique situation:
•No passenger: light is "Airbag" - No red flashing seat belt sign
•Passenger with seat belt: light is "Airbag" - No red flashing seat belt sign
•Passenger with no seat belt: light is "Airbag" - No red flashing seat belt sign
I have no other warning lights on the dash.
I tried to check to check if there are any loose wires/connectors under the passenger seat but everthing looks ok.
Is there a blown fuse?

I have been riding my motorcycle for the last few days and now I went to drive the 2001 Prius. Car started and ABS and BRAKE is lit and won't clear. The car ran fine last week and no issues. I did have a strut loosen on the front left and made a metal to metal clunking on bumps. I had a shop use an air tool to tighten the top of the strut. Drove for a week with out issues after this and then parked the car for a week.

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.

I have a 2002 prius with 147612 miles on it and a problem with my braking system. When I turn on the car the ABS and Brake light turn on and there is a high pitch sound that beeps continuously. Sometimes after a while the warning lights and beeping stop only to return a little while later. I can drive the car when the warning lights are on but i have to press harder on the brakes than normal to get the car to stop and the braking system feels looser. However, when the warning lights turn off I can brake as i normally do and the system feels normal. This problem goes on intermittently as I'm driving.
I took the car to the dealership today and paid $143 for a diagnostics and was told that DTC C1251 was retrieved from the diagnostic computer. The technician told me that the ABS Motor is bad and because of that the car thinks I'm skidding so the ABS shuts off. He recommended that I get the ABS Motor ASSY ( Part #47071-47010) replaced.
Also, I read a post to resolve it by flushing the brake fluid. I checked the brake fluid level in the cylinder and it is at the max level and there aren't any leaks. Would that be an option?

I just hit a pot hole this morning. Not too bad but instantly the abs/brake light and chime came on. Parked the car and turned it on and off to no avail. I drove home while the car was very hard to stop.

I'm completely new to hybrids. I have a 2001 Toyota Prius with 146k miles and its been running very good until some weird things started happening during the past couple of months. When I start it up, the brake light and abs light come on along with a steady high-pitched noise and grinding noise (sounds like ice being scraped). While the lights are on and the sounds are being made, the brake becomes very soft/"spongy" and goes down to the ground without much force at all (It usually always does this when I start it up and sometimes - but not very often - when I'm driving). Sometimes it all goes off and everything is normal again after about 10 mins, sometimes all day, and sometimes only after a minute or two (It usually does it on a cold start, but sometimes even if the engine is heated up, it does it).

I have a 2002 Prius with about 150,000 miles on it. A couple weeks ago, I noticed that the parking brake light on my instrument cluster didn't light up when I engaged it. Soon, all 10 bars on the fuel gauge started blinking. The seat belt reminder, open door warning, and headlight indicator lights aren't working, either. Any clues as to what could be causing all these malfunctions, or have I had more than one problem develop in close succession?

Just recently, my Brake light started coming on, on my dashboard for several seconds or more then going back out. I checked the fluid and it was fine. The next time the brake light came on, I noticed that the needles for Both my Speedometer and RPM gages dropped to zero for as long as the Brake light was illuminated. Once the brake light went off, the needles once again showed my speed and RPM (were functional). This occurs while I'm simply driving down the road.

I haven't driven the Prius for months. The other day, I needed it and tried to start it up but of course, it was dead. I should have known that would happen but I'm pretty clueless when it comes to these things.
So, I jumped it with another car, making sure not to reverse the polarity by doing it wrong (I think I did okay) and sure enough it started...for about 5 seconds and then died. The car we were using to jump it was on just like the manual said and we pushed it to 2,000 RPM again, just like the manual said. We tried it again and it comes on for about 5 seconds and then goes right back off. We even juiced it for about 3 minutes straight at 2,000 RPM and same result.
The display comes on and the icon with a car and an exclamation mark is red. What should I do? I guess the v12 battery is dead?

Picked up a 5spd 98 Passat w/AEB issues... 117K miles
Oil light & buzzer comes on once warm... so I flushed with Mobil syn 0-40W (previous owner was using whatever oil).
Dropped oil pan, changed out oil pump w/Meyle oil pump (good sludge & nice metal shavings)
New Mobil syn 0-40W - engine runs smooth...
Issue.. oil light and buzzer are intermittant, engine runs & sounds great.
Mechanic tells me coil packs can induce noise into electrical and cause nuisance warnings like this.
Rather tentative to drive with oil buzzer & light going on/off... Any way to ensure another trouble free 50K miles

I just purchased a 2014 Prius C and am having a problem with the Hill Start Assist/Control.
At every single stop, no matter how lightly I press the brake, when I release the brake the car stays in place for two seconds (no gas), and then starts moving.
I am assuming this is the HSC and not a normal function on the car.
If I depress the brake all the way no lights come on, no buzzer sounds, but the above described behavior still happens. I've tried the light stops on up hills, down hills, and flat ground, it all is the same.

2001 Prius. It started few months back where I get all kind of codes and the heat gauge shows up for like 30 seconds then the Triangle and Check Engine shows up. I used to pull over and disconnect the 12V battery but I found later on that the car would keep going fine even with all the Gauges on. I did replace the air filter. The issue almost gone away when the weather got colder. I just had to reset the battery after 40 mile or so.
Now, the overheat light comes on and after few seconds, the car just lose power and wouldn't respond to the gas. I have to disconnect the 12V battery or sometimes I just have to turn the car off for a minute or two and that might clear the lights for the overheat. The other day I turn the heater on to see if that would cool the car. Inside the car it was hot as hell but when I pulled over and checked the Radiator water, it was as cold. Is it possible it is the transmission that gets hot? The car now as not having enough power even just when I drive it while it is still cold. The only code I get is c1259. unplug the 12V battery and plug it back in is not clearing this code.

A few months back, I posted a problem with my '01 prius: engine knocking for @30 sec when first starting up. Does NOT happen on first start of day, only on subsequent ones. Random misfires not corrected by changing coils/plug. It's been in the shop for awhile, and no diagnosis. I'm ready to sell the thing, unless there is a quick fix. New hybrid battery 20# miles ago; used transaxle 10# miles ago (with 1.5 yrs left on 2 yr warranty); new tires 10 miles ago. Has 185,000 miles.

So My battery seems ok but the engine is running when I'm stopped a lot the last couple of days. I also hear a click from under the hood every once in a while like something is turning on.
Trying to even the voltage on a cell? I'm in SoCal but it's not hot or cold out.

2001 Prius. Within 15 seconds of starting the engine, I captured the screeching sound from the engine bay. Noise went away after about 20 seconds. New serpentine belt and new 12v battery installed. Pass dealer 27-point check. Transmission fluid, inverter fluid, high voltage battery were replaced about 18,000 miles ago. Current mileage 174,000.
Noise is not from the serpentine belt. I attached a mp3 file of the sound. "2001 Prius Noise.MP3" ..... Which component is making this noise?
