Prius (2004-09) :: Master Warning Light / Red Triangle Exclamation Point And Check Engine Light Came On
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.
Prius (Gen 2) :: 2004 - Red Triangle Warning Light Came On And Went Away?
The red triangle warning light on our 2004 came on and went away again It has 100k miles If I take it to the dealer can they pull some codes and figure out why it turned on We have to drive the car to 600 miles for the upcoming weekend and I don't want to be stranded on the side of the road The car has 103,000 miles We just replaced the 12v battery so I know that is OK
I also saw the following things to check. Is there anything else we should check?
1 - Are any warning lights on besides the red triangle? For example, the red BRAKE light, the amber ABS and VSC lights, or the amber circular icon?
2 - Did you check the brake fluid level? If low, buy a new container of DOT3 brake fluid and replenish as needed This fluid will dissolve paint, so do not spill it
3 - While you are at it, check the radiator and inverter coolant levels by looking at the translucent reservoirs behind the radiator and next to the inverter If low, fill with Toyota Super Long Life Coolant
Prius (Gen 2) :: Big Red Triangle And Hybrid Warning Light
The last few weeks I've been noticing that, upon start, the hybrid battery is showing at 1 line. It's been really hot in SO cal and the air con has been blasting, so I've been letting it charge up a bit before driving. Once I'm on the road, the battery charges fine and seems to hold a charge.

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.

This morning I went out to warm my car up for a few minutes because it has been so cold and when I started it the red triangle warning light stayed on and the consumption screen said "problem" across the top with a little icon in the upper left hand corner that looked similar to a high beam headlight indicator. I turned the car off and started it again wondering if it would clear which it did not. I left it running and went inside to get my child and by the time I came out it had cleared itself.
In typing this I recall that I thought it stayed on a little longer than normal the other day and just ignored it thinking it was still in lamp test mode on initial start up.

Every now and then I get the amber light with the triangle surrounded by a circle. Then the trans starts shifting real hard. When I restart the car it goes away, but comes back every now and then. Especially when I am in traffic after a long trip.

I bought the used 2006 Lexus 148,000 miles few days ago now when driving its showing on the dash check PCS system.
I took it to the local garage they plugged in Techstream and said they are no faults are recorded.
I called today Lexus Oxford, Lexus Reading and they said they will start with the initial diagnostic diagnostic using the Lexus software and will then proceed further according to the trouble codes.
I told them that as the local garage have used Techstream were unable to find any trouble code, after that they said that they have to start with the initial diagnostic and will charge me for that and after that they will they how many more hours are need for checking , its ridiculous .
1) Check PCS System.
2) How can I check the health of the Hybrid battery as battery bars are charging and discharging too quickly.
Lexus ES 2007-12 :: Red Triangle Warning And PCS System Check Light Lit Up
After driving most of a day on the road a red triangle warning light came up on the dash and a PCS System Check light lit together with a Check PCS System message in the display site. I checked the fuses and they seem to be Ok. The car runs fine and I don't feel any effect on driving the car due to this message.
View 2 RepliesPrius (2004-09) :: Red Triangle / Engine Light And Oil Warning (P0340)
I bought a 2006 Prius. A few days ago the car was driving along just fine when the red triangle appeared together with the 'problem' message followed by the red oil warning displaying in the top left corner of the screen. A few seconds later, the yellow engine light lit up and I drove the remaining mile or so back home (very slowly and carefully). I should point out that the car didn't drive any differently after these warnings appeared and I haven't noticed any strange sounds or anything like that.
I've been out to the car on a few occasions since. It goes into ready mode just fine and drives perfectly in EV mode. The triangle and oil warning reappear shortly after the engine cuts in every time it's started. The hybrid battery charges and discharges on the display when it's left at idle as normal. A friend of mine has a cheap and cheerful diagnostic machine that he brought over and that pulled the P0340 code which relates to the camshaft position sensor. That sensor has been replaced for a brand new one and the fault codes cleared but the code is still showing.
Santa Fe (DM - 2013+) :: Triangle With Exclamation Point Warning Light
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?
Prius (2004-09) :: Check Engine Light And Red Triangle Warning Came On?
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.

Yesterday I parked on a very slight slope (the front sat maybe 1 half to 1 foot higher than the rear) for a few hours. It was the end of my carport. When returned to move it forward and park, it was dead. So I put a charger on it and got it started but then the red triangle warning light was on saying that there was a problem with the parking system.
View 11 RepliesPrius (2004-09) :: Red Triangle Warning Light Started Coming On When Stopped
I have an 06 Prius with about 170k miles. The hybrid battery was replaced shortly before I bought the car last year.
About a month ago, the red triangle warning light started coming on when I'm stopped. It usually stays on for a few seconds once I start moving again. The MFD just says "Problem" for a few seconds, then displays the icon for a headlight. Once the light clears, the MFD goes back to its normal display. Originally, it was lighting up once every other day or so, but now it's lighting two or three times per trip. I'm going to have to do something about it, but I'm trying to get my head around what to expect.
My understanding is that the red triangle could mean anything from "The door is open and you're moving. Please close it." to "Your car is about to melt down! Seek cover!". I have an Automatic OBD dongle, and it's not reading any diagnostic codes. But as I understand it, there's a whole different set of diagnostic codes that a "regular" OBD reader won't catch.
I keep seeing reference to ScanGauge devices -- do they read the second set of diagnostic codes? I talked to a mechanic in the area who will read the codes for about $100. Is the mechanic likely to be reading the codes with that tool/is that what a dealer would use to read the codes? Is the dealer likely to charge to read the codes?

Prius (2004-09) :: Spontaneous Door Unlock / Triangle Warning Light
A weird thing happened to me just now in my 2005 Prius -- several times, while driving, the doors spontaneously came unlocked, while the red triangle with the exclamation point flashed on the dashboard. I was able each time to relock the doors from the master switch, and nothing else seemed to happen. At first, I thought I might be accidentally hitting a button on the key in my pocket, but I couldn't reproduce the effect by intentionally hitting the buttons. I stopped at my destination (Home Depot) and hoped the problem would go away as suddenly as it appeared, but it happened again on the way back. I have SKS. The key is a relatively new one that I had made some time after I got the car in 2010 (so 2011, maybe?).

View 3 RepliesPrius (2004-09) :: Hybrid System Warning And Triangle Of Death Light On
A few days ago I was driving my 2005 Prius aggressively up a mountain road and all at once the hybrid system warning light, the triangle with the exclamation point, and the regenerative brake system warning lights came on.
After about 2 minutes parked, I restarted the car and the regenerative brake system warning light went off, but the other two were still on. I still drove it twenty miles home, over another substantial mountain gap (about 1000 ft up and another 1500 down), without any problems.
I checked the voltage of the 12v battery, which seemed to be on the low end, but OK. (I think the lowest reading was 11.9). There seemed also to be some turbulence in the inverter coolant reservoir.
I brought it into the electronic vehicle specialist in town here today, who pulled my codes and said that the hybrid battery was dead.
Prius (2004-09) :: Check Engine / Triangle And Hybrid Warning Light Came On
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?
