Prius (2004-09) :: Multiple Warning Lights And Buzzer During Abnormal Braking Conditions
Aug 1, 2011
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 a 2006 Prius with approximately 112,000 miles. It has been a merely perfect car until yesterday. Everything was driving normal on my way to the store. When I turned on my car to leave the store a half hour later, the red exclamation point of death showed up along with the check engine light, ((!)) and the VSC signal all came on. Upon reading on this site, I decided to run the 12V battery test through the nav screen and sure enough, I believed that is what it was. I bought a battery and had it put in. I left the shop and and all the dash warning lights went off. When I restarted my car 10 minutes later to head back to work, all of those exact warning lights came on.
I ended up taking it into the Toyota Dealership Service area. They tried to reset the dash warning lights by pulling out the battery fuse (I think that's what they are called) in the front box of the car. It didn't work so they gave me the option to pay for the diagnostic ($98) or leave and drive around and hope everything is fine. I wanted peace of mind, so I had them do the diagnostic.
The assistant service manager came back 1.5 hours later and told me he had bad news. He said that there were faulty cells in my hybrid battery, which is why the service lights remained on. I almost started crying, sharing that I had thoroughly researched the prius before buying and that this forum, specifically had almost no talk of this...that is rarely if ever happened, that it needed to be replaced. He said in his 15 years at Toyota he had only seen it a couple of times. He told me warnings to look out for is if my car won't go above 25 miles an hour or it could technically start using only the gas side of the engine. He also said that the car just needs to "relearn" how to operate after replacing the 12v battery and it could essentially be fine.
He then quoted me $3500 if I ended up down the road of needing the battery replaced.

I had noticed a drop in MPG in the last month (more than normal this time of year), so I started searching on PC. That lead me to testing my 12V battery 4 days ago, with the following results:
No load: 11.8V
Load: 11.5V
Charge: 14.2V
Car started and ran fine, but since the battery is the original on my 2006 with just under 130,000 miles on it, I figured I'd get a new 12V the next time there was a good deal at Advance Auto. No other symptoms until today. After driving around 150 miles on Saturday, the car sat for 3-1/2 days in 25-40 degree temperatures. Started and ran fine today. Did a 5 mile trip, followed by a 1/2 mile trip, followed by a 5 mile trip home.
On the way home, the car lit up like a Christmas tree (appropriate for this time of year). Master warning light, brake system light (yellow; not red), check engine light, VSC light, hybrid system light (no ABS light). Turned it off and restarted and the VSC wasn't lit, but everything else still was.
More info... I finally got around to disabling the back-up beep, and the driver side seat belt warning yesterday, which may have run the 12V down even more.

I have a 2005 Prius that financed from a small dealer last year. Currently has over 140k miles on it. When I bought it it had the Red Triangle and it worked fine until recently (about 2 months ago). Recently I've been having some problems. When I go at higher speeds I get the following sings come on:
1. Red Triangle
3. Orange check engine light
2. Orange (Symbol)CHECK - Malfunction Indicator Lamp
3. Orange (!) - Brake Warning Light
4. Orange VSC - Vehicle Stability Control Warning Light
When these lights are on, my AC stops blowing cold air. Sometimes when all these lights are on, the car will slow down and will not let me go past 37 MPH I have to then pull over turn the car off and then on, then the lights turn off and I can drive normal, on short trips that is.
Recently on a longer trip over 50 miles or so all the lights I mentioned came on plus the red break light on the left turned on with a continuous beep. We pulled off the HWY and turned the car off then on and the lights disappeared except for the big red Triangle that one is always on. We continued driving it but it kept doing it so we had to let it rest for over 30 minutes. We had to take it really slow and we finally got to our destination.

The check engine light came on a few times. Went to the old trusty repair shop and the codes pointed to an issue with the catalytic converter. When we started the car again, multiple warning dash lights came on: ABS, (!), Check Engine, and emergency brake light. The brakes also felt very stiff after this.
The mechanic at the shop was taken aback. Said there was a glitch with the computer and that we needed to take it to a dealership to have them "perform initialization of linear solenoid valve and calibration." He said that would fix the issue with the lights.
We were a little upset this happened but love this shop and only stopped going because we moved a few hours away. The mechanic has always been very honest and upfront through the years.
I took the car to the local Toyota dealership today, told them what happened and what the mechanic said. All they did was charge me $100 for a diagnosis of bad catalytic converter pipe and tell me that all the lights came on because the catalytic converter is so far gone. They said they couldn't turn the other lights off until the catalytic converter was replaced.
I don't understand why my brakes are affected when the issue with the car is the catalytic converter. I was also told by the guy at the shop where we first took the car that we would be able to drive with a faulty Catalytic converter with no problem.

2009 Prius w/ 29,750 mi [Maint Req Light came on at ~28,000 mi]..
I am getting a Master Warning Light (triangle), a Hybrid System Warning icon, a VSC light, a (red) Brake Warning icon and a Check Engine icon. When the car starts, the A/C is fine but quickly loses cooling output especially with full throttle. regardless of manual or auto setting. Throttle feels a bit spongy and slightly unresponsive.
4 blue bars on charge and everything else appears OK.

I most recently drove my 2006 Prius around on Saturday Feb. 1, with no problems at all. I went out of town for a couple of days, and returned this afternoon to a car that will not start. I stepped on the brake, pushed Power, and things lit up, the "Ready" light flashed a few times but then went off. Power button light stayed orange.
Several warning lights on dash stayed on (!)/ABS/VSC/traction control, and a message came on the screen saying something about a problem with "P" parking, and that it should be parked level and the parking brake applied. It is sitting level with the parking brake applied already. Also, the door ajar warning light and beep start as soon as you open the car door to get in.
I'm thinking from what I've read that my 12v battery has died/is dying. I'm the original owner, bought car in March 2006, and it has just under 61,000 miles on it.

My 2005 Prius has about 140,000 miles. I had been getting the intermittent warning message, "Caution: The transmission lock mechanism is abnormal" although the vehicle has been able to start and drive just fine. I replaced the 12v battery, which was suggested in several other threads. However, the warning keeps reappearing. Possibly related, my gear shift knob is "sticky". I'm able to get it into each gear (and the transmission remains in the gear selected), but the knob does not move smoothly like it used to.

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.

My 2006 prius started beeping and showing multiple warning lights - The big triangle with the exlamation, Brake System Warning light and Check Engine light on the dashboard. On the main screen the hybrid system warning icon popped up.
I asked from a toyota service place and they said this might be due to multiple reasons (they didn't mention exact reasons) and will cost a lot of money. I've been checking some posts and found some advice regarding the inverter cooler. I checked the coolant container for "waves" as instructed by this post Suddenly hit with multiple warning lights! | PriusChat.
I can see the coolant moving when I turn the car on. What other reasons that can cause this issue?

I drive my 2005 Prius 40+ miles each way for my commute. I bought it in the fall of 2007 with 56k miles already on it, and with my commute I'm up to 140,000 miles already.
This morning I was about 5 minutes from work, cruise control on, and deeply absorbed in listening to a podcast. I was startled out of my reverie by several things happening simultaneously. The car beeped, the cruise control kicked off, and multiple warning lights lit up on the dash, with a warning icon of some kind also on my MFD.
(Once stopped, I looked up the warning lights. They were: Master warning light; Check engine light, or "malfunction indicator lamp", according to the manual; YELLOW Brake system warning; VSC warning light. On the MFD, the Hybrid System Warning Light was on.)
I was on the highway doing about 70 and I had just crested a hill, so I allowed the car to coast on the downside while trying to access the situation. I cautiously pressed the accelerator, and though the road noise made it impossible to hear the engine, the car seemed to still be driving normally. The Energy Monitor still showed normal flows between battery, engine, and wheels. I had one final, short uphill climb before my freeway exit, so I chanced it. I took it easy and allowed my speed to decrease on the uphill so as not to push too hard, just in case. Once off the freeway, most of the remaining mile is downhill or flat - I can often make it to the office without the engine, and in fact I did so this morning.
Once at the office, I put the car into Park and grabbed the manual so I could identify all the warning lights before powering off the car. I turned off the Prius, let it sit for 5-10 seconds, and powered it back on. The brake system warning and VSC lights did not come back on - only the master warning light, and "check engine" lights reappeared, and "Problem" on the MFD was again replaced by the Hybrid System Warning icon. After the usual 10 seconds, the engine started normally and responded to the accelerator.
One additional note: After the freeway exit, my car is usually at 1 green bar or just below on the hybrid battery. Immediately following the freeway exit is a steep downhill that usually puts the SOC to completely full. That was the case again today, and as often happens, that full charge was able to take me the rest of the relatively flat, distance to the office at my usual 25-35 mph. I mention this because whatever might be setting off the warnings, the Prius still seems to be managing the charge level normally; at least in the admittedly short period I was able to observe it after this occurred.

Thursday afternoon I drove about 120 miles total in my 2004. At about 40 miles I left my wife to shop and drove on to 3-4 other stops for myself and then came back to pick her up for the 40 mile drive home. When she got into the passenger seat, she found that the carpet & mat on the floor were sopping wet, so we put some heavy towels over the wet area to protect her shoes. When we got home (with NO operational issues), I removed the passenger floor mat, put several thicknesses of more heavy towels on the carpet and placed 2 concrete blocks on the towels to soak up the water.
On Friday, I changed the towels and did not use the car. Saturday, I removed the towels, concrete blocks, and went to start the car so I could see if there was water dripping from under the dash from a plugged condensate drain, since I had not driven in rain or water on Thursday. The dash displayed every warning light imaginable including "check engine", hybrid system warning, slip indicator, brake system warning, Master warning (!), VSC, Maint reqd. Now it is Sunday and I still cannot get to the "Ready" light so I can start the car. My traction battery condition was solid green yesterday, solid blue today. The radio, interior lights, A/C fan, door locks, etc. all work.
Could there be anything under the passenger carpeting (or behind the dash which might have gotten wet which could be causing these problems/codes?

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.

I have a 2006 Toyota Prius and it won't start after it was detailed. No engine detail. The key will still lock and unlock the car and when I press the power button sometimes nothing happens and sometimes multiple indicator lights go on and off. The battery is not dead but it may be low and the car was working perfectly before it was detailed. The doors were left open for some time and I'm sure buttons were inadvertently pressed during the cleaning. I tried to jump start but no luck. Is there a way to reboot the system or a way I could troubleshoot before we tow it to the dealer?

I just got a call from my dad about his Passat, and am doing some research for him. He said that on his way home just now, the warning buzzer sounded, and that the 'brake' light, ABS light, traction control light and oil light all came on simultaneously. He was stuck in traffic, so couldn't pull over immediately... after about 10-15 seconds, they went off again. It then repeated once or twice for a few seconds later on the drive.
I've just done a bit of searching, but it is hard to know what to search for in this case. I did see some threads about a defective ABS module triggering the ABS and Brake lights, as well as a bad brake light switch (don't know if that has been replaced on this car yet). But that doesn't cover the Oil and ASR lights as far as I know. Any other possibilities?

We have a 2006 Prius that has never given me a bit of trouble the last 24 months or ownership. My wife was driving a few weeks ago and had multiple dash lights come on while stopped at a red light but the car was still acting fine. Light turned green she drove a couple miles at about 45-55mph to the gas station, shut her down, came back and everything returned to normal. Today it happened again but this time she got a picture of the lights that was on. SEE ATTACHMENT BELOW. the TPMS is always on by the way.

I own a 2005 prius that I purchased used this year. This morning I had my first issue. I turned on the car and it gave me the following error message:
"Transmission p lock mechanism is abnormal. Park your car in a flat place and apply parking brake completely."
The parking break wasn't on and I was already parked in a basically flat parking space. I couldn't move my car because it wouldn't go into drive or reverse or neutral. (The car turned on, but the engine wouldn't start). I tried turning the car off, but the car also wouldn't turn off. I let the car sit for 5 minutes then tried again and the car turned off. When it turned back on, everything was fine.
My questions is: Do I need to bring this into a mechanic? The car seems to work fine now, but I don't want to be stranded again or do damage to the car by driving it with an issue.

I was driving and the red BRAKE came on flashing and it beeped. Then the message came on saying Emergency Brake Failure - See Manual. Then the Emergency Brake light came on. Next the Antislip light came on. After a few miles another light came on - ESL or something like that. Then the ABS started kicking in almost every time I stepped on the brake. Later the trans stuck in 3rd gear.
Wouldn't upshift or downshift - even in TIP mode. I took it to the dealer the next day and they couldn't find anything wrong, so they gave it back to me and said to call baco or bring it in if it does it again. Then a week later it did the same thing except getting stuck in 3rd. Took it back again. This time the Emergency brake light was still on. They have had it since yesterday and still can't find anything wrong.
I suggested looking for a bad ground connection somewhere. They say they have done that. Battery is original but starts just fine. Also suggested battery cables.
It's a '07 B6 Wagon - 3.6L TIP ....

for the last three days, I had the big red master warning light come up four times during normal braking, also "Problem" was displayed on the LCD where "Add fuel" is displayed when fuel is low. But no error code showed on the OBD reader. I searched found that it might be related to 12V battery which I replaced two years ago.
2008 with 120K miles.
