Prius (2004-09) :: Master Warning Light / Red Triangle Exclamation Point And Check Engine Light Came On
Apr 22, 2014
My wife and I own a 2006 Toyota Prius that we bought used 2 years ago. a couple of days ago, the master warning light (red triangle exclamation point) and check engine light came on. I took it into the dealer and of course, our hybrid battery was dead - battery and a new ECU required.
Our car is at 99,000 and 32 days out of warranty. Went down the road to atlanta hybrid repair. they were incredibly nice, and said that my computer was fine, but the battery would need to be replaced.

My wife's Prius now has the check engine light, the orange triangle, and the car with the exclamation point lit up. It only has 96,000 miles and hasn't been in a wreck that we know of. I've read that it has to do with the HV ECU, but I don't know much more about it. Is there any chance it's just a loose cable or something simple? It doesn't seem like her car should already be having so many extensive problems all at once. We haven't had any in the past, except the car with the exclamation point came on for a few days and then went away on its own.
Codes: P1636, P3106, P3002, P3006. It's a 2002 Prius

Recently bought a 02 with 34 K, had been well maintained. Last night it wouldn't start so hubby jumped it (properly). Started right away, making him think that wasn't what it needed. Right after that, the Master Warning light came on, the Car with Exclamation Point in it (hybrid system warning light) and the check engine light. The car runs, but it did die, and I had to restart the car, then seemed to drive fine. We don't live near a Toyota dealer, would a regular mechanic be able to read the codes properly? What else should we consider? Should we drive the car?

I am getting a 3006,3011,3015 code from my 2001 prius. The car only has 56k miles on it but sat for 8 months without starting or unplugging the batteries. I am wondering if i need to replace bank 1 and 5 on the battery to get the engine light off? The car runs fine and drives great but engine light is on and the triangle exclamation point is on but that's it for lights. What do i need to do? Replace battery altogether? recharge the effected banks?

2014 Santa Fe Sport 2.0T FWD / 16,000 miles. All fluids full / up-to-date
On two occasions we've had a warning light appear that is not the CEL. It's a triangle with an exclamation point in the middle of it. The first time, my wife called and told me about it and it only appeared for a few minutes and disappeared. I checked the codes and there were none--that was several months ago.
The second time it happened (a few weeks ago), I was driving on an interstate at 70 mph with the cruise control on. The aforementioned indicator light appeared for about two minutes and disappeared. I immediately called Hyundai Bluelink (within a minute) and asked them to look at the code history and they advised they couldn't see any indication of malfunctions. They further advised that indicator meant that maintenance was needed and that I should make an appointment with the dealer. I pushed them for more info, but the operator remained vague about what maintenance my Santa Fe required.
Why does it only illuminate for a few minutes?

I just noticed this morning that the "warning" light (orange triangle with exclamation point) is on in the Multi Info Display in the middle of the dash ONLY when the engine is off. I scrolled to it and it says "check charging system" with the battery logo. When i turn the engine on, the warning light goes away.
The battery logo does not light up where the gauges are. Does this mean the battery is okay? Its confusing and the manual does not clear it up.
Am I correct in assuming that I'm low on battery only if the battery logo lights up where the gauges are? I have no issues when starting the engine or anything.

My 2008 Prius has approximately 116,000 miles on it, about 8,000 miles ago, I put on a Mobil 1 Extended Performance filter and 5W 30 Mobil 1 Extended Performance Full Synthetic Oil. Over the past week, My "Exclamation Point Triangle Light" (Not sure what it's called) has flashed a couple of times when coming to a sudden stop and the car would emit a "beep".
My first assumption was low brake fluid, but today when I got home and checked the fluids, I found the oil to be approximately 1.5 quarts low... I have not noticed any leaks under the car (I park in the same spot at work daily), and haven't noticed any smoke coming from the rear...
What the problem might be? Is it possible I might have damaged the engine by driving on such low oil for an unknown period of time (guessing a couple of weeks or so)? I used to religiously check the oil in all my vehicles, but have gotten out of the habit on later model vehicles...

This morning I started my 2008 Prius (approx. 31k miles) and found the big red triangle with an exclamation mark and check engine light turned on.
I drove my car <1 mile to a smog check station where they ran a diagnostic on it and came back with the P0A9C code.
A quick internet search turns up that this is "HYBRID BATTERY TEMPERATURE SENSOR "A" RANGE/PERFORMANCE."

Check engine light, red triangle with exclamation, and on the monitor a red box with a picture of a car with exclamation came on after changing the rear brakes. I checked the water flow control valve and water pump. Don't know what else to check.

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.

I have a 2007 prius. I was driving home all a sudden I get a big red triangle warning and the engine logo came on. On the display screen its show a logo of the car at the corner in red with exclamation mark. I use the car obdII scanner but no error code came up. I decide to check the engine oil. When I remove the cap, I notice inside the engine it look weird like a gold color and some blackish. The engine cap inside look like it have stains on it too. The hole where you pour the motor oil down I notice that piece inside don't go down for the funnel to stick in. I attach some pictures. I have no clue what's wrong with it and I don't wanna drive it to make it worse. The prius only have 90k miles on it.

Possible hybrid battery failure in my 2004 Prius (96K miles).
Sunday before last, the check engine light, warning triangle, and hybrid warning light came on when I started my car at the grocery store.
Because I was close to home, I drove home and the car functioned completely normally. The next morning, when I started the car, the same warning lights appeared. However, when I tried starting my car with the headlights off (I always leave them on), no warning lights appeared.
I took my car to an independent mechanic. This is their written report:
"Found multiple check engine codes, P3000, sub code 123, V0100 sub code 211/330. These codes are set when high voltage control detects a malfunction in battery pack/ECU assembly. To check battery pack we took vehicle out on a test drive while monitoring the cells in the battery pack. Found that they are all weak and drop fast when battery is put under a load. Code C2318 is a low voltage error/power supply malfunction code with the auxiliary battery. The voltage spec for setting the code is 9.3 volts, this battery is less than 9.2 volts."
In conversation, the mechanic also told me there was significant voltage variation across the cells in the hybrid battery.
I then took my car to the dealer to try to confirm this analysis. They were unable to read any codes because the independent shop apparently cleared them. The dealer was unable/unwilling to do more than read the codes to diagnose the problem. (Indeed, they seemed surprised that the independent mechanic could monitor the cells in the pack.) All they did was to drive the car around some more to see if the check engine light would come on. It did not.
The car has been driven 80 miles since the warning lights last appeared and appears to be behaving normally. From your perspective, does the report from the independent mechanic make sense and is it believable? And is their test under load definitive of a hybrid battery problem? Could the results be affected by the low auxiliary battery? Also, if I do have a hybrid battery problem, what are the chances of being suddenly thrown into limp mode while driving it?

Stopped at ATM when heard a thump under seat and all the above appeared on control panel. Waiting on computer code reader to test vehicle. Any clues to what all this means. Vehicle 2006 with 101K. Recent service as scheduled with coolant and inverter coolant and belt replacement done. No other issues to date with vehicle.

My Prius has about 145K miles on it and use it on a daily 130 mi round trip commute. Recently, a I got a Red Triangle w/ Exclamation Point and the displayed showed "Problem". I took the car to the dealership and they stated the problem was caused from a low oil level. The dealership changed the oil and I was good to go. 3k miles later, I got the same error and noticed my oil level was low once again. It seems that my Prius is burning oil at rate of 1 quart per 2500 miles driven. What can be causing this? Are there any remedies I can try before changing out the piston rings?

I am getting the red triangle and the little car with exclimation point on the MFD. Interestingly all of the amber lights are on and the brake light is on BUT the parking brake is not set.
Here is what happened --my hybrid battery died a few weeks ago so I ordered a replacement through Summit Racing (Dorman Battery). The car started and drove but I had to rest codes to keep it alive (just to get it home). Last moved it 3 weeks ago and removed the old battery.
So long story short -- while I was waiting for the new battery I repaired some other issues -- BTW I am not new to this, I have the tools and have done these repairs on conventional cars many times.
1. Leaking axle seals -- replaced L and R seals
2. replaced L and R half axles (drivers side was rough so replaced both)
3. Found drivers side wheel bearing to be rough so replaced L and R hubs
4. Replaced L and R struts and strut mounts.
5. Drained and refilled trans axle with Toyota W (TF) 4 qts
6. Installed new 12v battery (currently producing 13.4v)
7. Replaced rear struts.
8. Replaced L and R front rotors and shoes -- they were off anyway so why not. No loss of fluid!
9. Removed and cleaned most interior parts -- door panels, seats etc...
Installed new HV battery and fired her up to the usual wheezing, whining and clicking sounds. But NO engine -- just the triangle -- problem statement and and the other above issues.
Checked the following -- inverter pump is circulating nicely, though maybe battery electronics -- so I placed the old battery back in (it was started with the old one 3 weeks ago) -- nope same issue so not those electronics. Traced all wires, plugs and connectors related to hybrid system -- all seem to be in place.

The triangle comes on momentary for the past week. It first occurred when I turned right at 20 mph. The next time was during a sweeping left turn. Off and on with turns left and right. the last few times it was longer in different situations and I could read the LCD display where is said "PROBLEM".
The local dealer said check brake fluid and open and close all doors. Since it is more frequent I called my mechanic and he thinks it could be door sensors that have built up junk. The dealership does not think it is a safety issue and without any lights on their analyzer could not pull any codes.

2001 with about 117,000. Just had it in to get the transaxle fluid replaced for preventative measure. Now I'm getting an intermittent triangle/exclamation warning. It seems to go off if I let it sit, mostly. Runs ok for the most part. But when that comes on, it practically limps on very little power.

I have a 2007 Toyota prius base model, it has 49,845 miles. Today i got in, pressed the bake, pressed the on button, and the Red Triangle appeared with yellow exclamation point in a circle, and on the lcd monitor it shows that there is a problem and a little icon of a car with an exclamation point on it.
The car drives and runs normal, fuel mileage seems to be the same, everything looks normal except the lights. One thing I tried to do: I took off the battery clamp and i put it back on, the warning lights were gone, but as soon as the engine kicked in the same warning lights came on.

I have the red triangle with the exclamation point in it. What it can be? I have a 2006 Prius. It still seems to drive ok. I have parked it though and have an apt Monday morning at Toyota. (They didn't have a Prius tech in today) When I first noticed the light it would come on and go away. Now it's staying on.

I have a 2008 Prius, with SKS and Nav, and 103,000 miles on the odometer. I bought it from the original owner in 2010. So far it has been trouble free, with just oil changes and scheduled maintenance.
When I turn power on, I get a red triangle with exclamation point. Also a row of yellow indicator lights. Also along the top of the LCD display there is a red car shape with an exclamation point on it.
I followed the procedure for checking the voltage of the 12v battery using the diagnostic screens, using the procedure at weird-stuff-happening-mpgs-dropping-test-the-battery.73400/and I got 11.8 volts.
Since it seemed likely that my problem is related to the (original OEM) 12v battery, which is now 6 years old, I took my handy jump-start battery thing (see photo below) and attached its red alligator clip to the positive post under the hood, and the black clip to the frame. I hoped that would allow me to start the car, but it did not start. The error lights on the dash were unchanged.
Question 1. Does the fact that the symptoms remain the same after I have connected my jump-start battery mean that the problem I'm having is NOT my 12v battery?
I then hooked up my cheap OBDII code scanner (see photo below) and checked for codes. It found none.
Question 2. Does the OBDII scanner not finding any codes have any importance? When people write about having their car towed to the dealer and having error codes read there, does that refer to OBDII codes, or are they referring to some other type of codes that can only be read by a dealer?
While I was in the diagnostic screens, I found three screens of error codes. The screens are called DSP-AMP, EMV, and NAVI. See 3 photos below.
Question 3. Do these error codes have significance?
