Prius (Gen 2) :: ABS And VSC Lights Came On - Braking System Went Out
May 28, 2013
I bought my 2004 Prius back in October at a used Honda dealership. A couple of weeks after I bought it I was driving, had been driving for over 2 hours and made a stop. When I left from the stop and tried to stop at a stop sign, my "abs" and "vsc" lights came on and my brakes would not work for more than 5 seconds at a time. I could push them and it would slow down but then it was like my foot left the pedal and the brakes went out.
I pulled over and had the dealership come tow it to their shop and I left it there for a day. They called me to come get it, so I picked it up, and they never charged me anything so I assumed it was all under warranty or something. Now almost 7 months later I am having the same exact problem. I called the dealership to see what they did to fix it last time and they said there was no record that anything had been done to it, that they think it just started up fine with no problems when they tried.

My 2006 prius has the Master warning light(red) and the braking system light (Yellow) on while I am driving, and I went to the dealer.
The technician told me that he could not verify any warning lights ON at that moment, and he performed health and diagnostic checks on it. He inspected connection at auxiliary battery and junction box 1. All checked OK at this time. No repairs recommended at this time.
However, the master warning light came on when I pick up the vehicle. The dealer told me that they will inspect it again tomorrow. And they found that there a P0A08 error code. They suggested me to replace the hybrid converter/inverter.. My car can still drive while the lights ON.

Its a 2009 with about 75K miles. Back last year my wife drove through some thick mud, and this caused brake failure....yellow exclamation mark, VSC, and red brake warn lights all on and the buzzer sounding. I did not have mini VCI/ techstream at the time, but I went to car wash and sprayed out the insides of wheels heavily, and then did the jumper trick while pumping brakes 8 times, and the faults cleared and brakes worked perfectly for some months--- until this weekend. We had very heavy rain again, and the tires were encased heavily in mud again. I figured it must be a wheel speed sensor signal problem again. So I took it to car wash to clean inside of wheels.
Now I have the mini-VCI /techstream running on a laptop to check it out. I ran the health check and it came back with code C1365 for the ABS/ braking system. I cleared all DTCs, and the fault lights cleared, but the brakes soon failed again with the same dash indications. Tried once more, same thing. Then I remembered about the trick last year of jumpering the diagnostic connector. This temporarily clears the fault, letting the brakes work fine, until the next time you start the car. Then it comes back. I clicked on that fault code in techstream, and noted that code C1365 was telling me that the accumulator press. sensor voltage was below threshold. Should been at least 4.7 volts, but it was at 4.37.
But the brakes work perfect as long as you don't shut it down! So how can a part really be bad? If it is indeed bad as the code says, is this sensor replaceable by itself, or does the whole accumulator have to be replaced? Is it a job a DIY mechanic can do? I am able to at least drive the car, although my wife can't. I just stick two pins in the diagnostic connector, and I connect them temporarily with a jumper to do the reset trick before each drive.

Just purchased a used 2008 prius with 80,000 miles on it. Braking system makes slight grinding noises when getting below around 10mph. I know the brakes are different, so I'm not sure if this is normal or if it means my brake pads need replacing? Car didn't come with an owners manual .

Braking at a stoplight tonight, I had the VSC and ABS light come on. I pulled over to a parking lot and shut the car down. I couldn't tell any issues with the brakes at all in the short few hundred feet I drove to pull off. Turned it back on and the lights were no longer on.

I 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.

On my way into work this morning I noticed that my brake lights don't always light up under very light braking. Noticed this on 2010?

Weird problems with my 2006 prius. Car has 54,000 miles.
4 times now over the last year, during abnormal braking conditions (someone swerves over at me on highway and I have to break and swerve suddenly to avoid), I get multiple warning lights, and the warning buzzer. Yesterday this happened, and I got the red triangle, the red brake light, the abs light, and two new lights on the LCD display I've never seen before. I pulled over and began to slow down. The brakes felt stiff, and the vehicle started to loose acceleration power. LCD started resetting itself. I stopped the car, turned it off, and turned it back on to find everything normal. I then drove 200+ miles to my destination without incident.
This is the worst case of this problem yet. My 12v battery was replaced last year after the first of these issues, with similar symptoms, but no loss of acceleration. The tech said the only code in the system was a voltage spike, and thus thought it needed a new battery. In every other case of the problem, I turn the car off and turn it back on, and it's fine. I'm about to drive 2000 miles next week, and want to avoid further issues...

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.

I have a 2005, I purchased new in 2005. I now have around 120,000 miles and have had no problems - just oil changes and new tires.
I was driving on the interstate in MS and all of a sudden all these lights come on on my dash including the triangle that means take it to your dealer immediately. The car sounded funny acted funny and accelerated funny. I was closer to home so I came home and called the dealer. They said to drive it in but if it started acting up to pull over and they would come get me.
When I cranked it, it sounded like I was pushing the accelerator but I wasn't so I cut it off then cranked it again. I drove it very slowly cause it was acting weird.
I drove it home to discuss it with my husband and to do some on-line research here. So 2 - 3 weeks later my husband decides to look at it and by now the little battery is dead - it is the original battery too -btw. So I bought a new toyota battery (the little one). My husband hooked it up to see if the car would crank. It did but all the lights on the dash lite up again including a couple new ones!

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.

My Prius yesterday while driving slowly (under 10 mph) all the dash warning lights came on(triangle, cel, trac control, brake). the gas engine started and the message came on that says: "check hybrid system". Today when I went out to check there only two warning lights on (triangle and cel) with the same message displayed. My question is can the vehicle operate without damaging anything if I drive it as is? I have read on several threads that the engine will not start if the hybrid motor(s) are not working. Since my engine starts and runs I have to believe the motor(s) are working.

Have been having cascading problems since installing PIS 10kWh system in April. Early system shutdown, failed BMS boards, then triggering of Prius warning lights. The latter required disconnecting the 12v battery to 'reboot' and cancel them per Robb of PIS. But then, when attempting to do an electrical load test using air con & other accessories, we triggered several yellow warning lights that do no go away with a reboot. Have been told that we need to have a dealer read the codes to troubleshoot.

Our 2002 Camry SE V6 incurs a burning odor through the HVAC system after braking from moderate or higher speeds (at low speeds, this does not happen). It can last for a few seconds or a few minutes and then goes away (it does not happen while in motion). I cannot smell anything outside the car.
The car was inspected & serviced two months ago with no issues found. The front valve cover was replaced about a year ago but the back valve cover was OK to leave as is.
I would want to say it is the brakes or the snow tires causing the odor but it is strange it only smells inside the car.

My AM radio buzzes pretty bad when I brake or when the A/C fan switch is moved to any position except low. What can I do to eliminate the buzzing?

When braking at very slow speeds(less than 5 mph), my ABS system engages. It can be startling and the truck keeps rolling forward unless I pump the brakes to get it to stop. The truck is drivable, I just have to be careful when pulling into our garage or slowing behind someone at a traffic stop. What could be causing this?

I am the proud owner of a P.O.S it’s a 2001 Chevrolet Malibu, the trouble is with my ABS braking system. I replaced both hubs a year ago they have the ABS sensor built into them. The light has started coming on so I checked the voltage on both sides of the car the reading are, driver side at 169mv-320mv and the ohm reading is 1.02K, on the passenger side it reads 140mv-240mv the ohm reads 1.01K, one is a bit lower but well above the 50mv minimum. When I restart my car sometimes the light is out until the ABS kicks in on a wet or gravel road. Then the dash light comes on and the ABS system shuts down again, the only thing a code reader states is low voltage in the system but does not call out what side or where the low voltage is coming from…

My 2000 Ford Ranger 4x4 truck's anti-lock braking system is not working properly. When I slow down for a stop my anti-lock brakes kick in every time for about 1 or 2 seconds. What can I do to stop this from happening.

I have had this issue with the braking system for about a year now. Most of the time when using the brakes, everything works fine, but once in awhile, it seems like the brakes on one (I think one) wheel seem to just let go, apply full braking power, or both one after the other. When this happens, you hear loud clunking sounds (which I guess it the caliper going from on to full off and back again) and the rear of the car will raise and lower with the instances. There are also times when a high pitched squeak sound comes from the wheel (like when a bus uses their brakes) which will normally happen a second before coming to a full stop. It does not happen at the same time, but I think is related. Going off the sounds and rear of the car moving I tend to think this is focusing around the driver's rear tire. The brake fluid has been changed, the brakes have been changed on all 4 wheels, and so have the all brake lines to the cylinders. There are no leaks anywhere in the system. The car does have ABS.

I recently had my wheel hub and bearing replaced. The mechanic said I might hear a little noise with the brakes but they'd work. Turns out that noise is the Anti-lock braking system engaging every time I use the brakes. It happens when the car speed gets low, maybe 5-15 mph. Also, if I'm driving slow in a parking lot or something, and let off the gas, that change in speed sets the ABS system on too, without my foot being on the brake pedal.
I've also noticed sometimes when the weather is very cold, the ABS light will go on and the ABS brakes won't work; just regular brakes. Is this something that I'd be able to solve at home? Could I possibly bleed the brake lines to check for any air ( although braking seems fine ) , busted fuse for the system, anything else to check before asking the mechanic?

I've just had a brake controller fitted to my 2006 Treg R5. Everything is working fine however when braking both of the caravan indicator lights also come on too (but not on my treg). The tow bar was fitted by the VW dealer and the brake controller was fitted by my local tow bar specialist. After spending two and a half hours checking wiring etc yesterday, we're no closer to a fix .
