Prius (2004-09) :: Multiple Warning Symbols / Car Won't Go To Ready For Starting
Jun 26, 2016
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?

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 141000 miles on it. The red triangle exclamation point comes on the dash and a yellow exclamation comes on the LCD 1st and then a 2nd yellow symbol comes on the LCD. The problem happens once or twice a day. It seems to start, run, and drive just fine. I do restore antique tractors and I am pretty good with computers and I have some pretty good mechanical know how. Attached are pictures of the lights.

I have my 2004 Prius in the shop for a replacement of the HV battery pack. The car has approx. 120,00 miles on it.
The battery failed with all the lights, warning symbols etc. I just got a call from the dealership that its going to take longer than expected to get the car back to me. They have the battery pack replacement, but when doing the replacement, they noticed that the cables were "corroded." The cables for the battery need to be replaced before they will complete the repair. But the cables need to be ordered and won't be in soon.
Is this common? for these cables to corrode? Would this problem have caused the HV battery failure?

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 the dealer disable the beep in the "R" reverse position soon after I got my Prius. This worked great. After about a week, however, I now notice that the "R" symbol blinks whenever I am in the "R" position.
Also, when pushing the start button, the dash only showed the warning symbol and TRAC symbol for a couple of seconds and then went out. Recently, however, 8-10 warning symbols come on in the right part of the screen and then go out. Why this suddenly comes on?

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 bought an 03 with 58K miles on it. shortly after I bought it the check main battery light came on, after the local Toyota dealer told me I needed a new main battery. I had a P3000 code, a high voltage leak. It turned out to be corroded buss bars and cables, with 2 leaking cells, $1,450.00 latter the onboard computer said the problem was fixed and my display read normally for about 1,500 miles before I started getting that code and the check main battery light again.
I took it back to the shop tat did the work and they ran the diagnostics on it again, checking the main power cables that led from the main battery under the car to the Toyota Hybrid system, inverter? Under the hood they checked all of the high voltage connections, they all checked out fine. The shop then took several days to do an online search for possible causes. This led to the CV trans axle with its electric motors and generators as the possible culprit. The car is running and driving fine, so I did the 60,000 mile transmission oil change, suggested by my mechanic ( apparently the fluid becomes conductive with age) the check battery light will go off if I remove the secondary battery terminal for a minute or so and stayed off for 2 tanks of gas after the fluid change but it did come back on.
I can reset the computer easily enough and it will stay off for 3 to 400 miles but I'm looking to get the damn light to stay off. I'm going to change the trans fluid again. Changing the drive motor or generator?, can this be done in the car? or at all? It may be that if this is the problem it may end up making sense to just put in a new CV transaxle.

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...

When I backed up yesterday, some dash symbols showed up. After turning off the car, I am not able to get it in Ready Mode. Only solution so far: to disconnect the 12V battery and wait approx. 2-3 minutes. After that, the lights are off. The 12v battery does also indicates normal voltage. IG-OFF: 12.7V IG-ON 12.2 ... Unfortunately I cannot get the trouble codes with my scan tool ...

I recently (two weeks ago, actually) bought a one owner clean car fax 2007 Prius with 125k after totaling my 2004 - I got the 04 cheap enough that the payout covered the new one. The car ran perfectly; quiet, no whining or grinding noises, etc. About a week ago, the check engine light came on. The next day, I got in it to drive to school. I get to the middle of my campus and it starts to lag (very similar to the way my 04 did when it needed a new hybrid battery cell). I pull over and turn the car off and back on since that used to be what would get me home in the 04.
Every single warning light came on, including the master one. My "BRAKE" warning light is also on even though the e-brake is not. The car would not show "ready" and would go into park, but if I tried to shift into anything else, it would pop into neutral. (The dash as of now is shown below.) This is not user-error. I have driven a 2nd gen Prius before, I know about pressing the brake down when you start it. The garage I had to get it towed to has no idea what to do with it and each Toyota dealership I called told me that they hadn't heard of before.
I bought a new 12V and the garage said it didn't make a difference, but I'm not entirely convinced they even tried it.

What the warning lights mean (red triangle with exclamation mark inside, and yellow icon upper left of display, 2005 Gen II)? It comes on after starting the ICE, used to come on intermittently, now it's all the time... my hunch is the suspension because the ride has been getting worse, with unusually loud sound from the wheels over potholes!

for the past 2 years (ever since putting in a new battery) my Saturn as been setting off a constant alarm without the presence of the warning symbols on the dash. You know when you leave the keys in the ignition, and open the door and get that annoying klaxon alarm? that's what my car does all the time. sometimes it goes off by itself, but you usually have to turn off the car and "reboot" it. There are never any warning symbols lit up when it does this, only the alarm. I took it to my mechanic and he said that there was nothing he could do, taking out the fuse for the beeping would somehow disable the car? I will soon take a shotgun to the fuse box if I can't find out how to take care of this problem.

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.

I have a 2004 prius that sat for 2 years, I just replace a cell, worked on the HV battery and made sure it was balanced. I got the battery back in and I can't get it to go into Ready mode, I can get it to ignition on and charge the battery and into acc. I've checked several components to see if they were causing the issue.
- 12v battery is good
- brake light switch seems to be good as the lights come on when the brake pedal is pressed (but ready mode does not)
- I've checked a number of fuses
- used and obd2 adapter with torque and it is not coming up with any codes
-Edit-
- 12v battery was replaced last spring and has been maintained

My 2005 Prius won't go into READY mode. This has been happening for many times now almost a month. Up until today if I let it sit there for a while (sometimes a couple of hours) it would work eventually, however, starting today it just does not want to go into READY mode. One thing that I have noticed is that when I press the brake pedal the brake lights do not turn on. I have been suggested that it could be the Stop Light Switch that causes it, and one way to check was to perform the following procedure:
(1) Push the P position switch.
(2) Parking brake pedal is depressed.
(3) Turn the power switch from off to on (ACC)
(4) Brake pedal is depressed.
(5) Press and hold the power switch for 15 seconds or more.
According to Vincent if this starts the car then it is the Stop Light Switch but I was not able to start my car even with this procedure (may be I am doing it wrong.
Note: I have checked the 12V battery and it is not the problem.

I measured battery on my 2007 Prius by MDF, it's only 11.9V, charging is about 14V. When I turn on ACC mode, and Radio is on, I think it shut down the radio after about 15minutes; I cannot put the car in ready mode after it shut down. I have to jump it in order to put in ready mode. Is it my turn to replace this auxiliary battery?
