Prius (2001-03) :: Replaced HV Battery - Error Codes With Triangle Came On
I successfully replaced the HV battery on my own and it was so easy even this girl to do it! I drove the car about 300 miles when I got the triangle of death warning light again yesterday. I took my 2002 Prius to the dealer to read the codes but how to borrow a scanner (or whatever) from Autozone and do it myself.

I just acquired our second Prius, a beautiful 2002 (Gen1 in the USA) with 90k miles. On the dash, I get the red triangle of death with the exclamation point inside it. On the computer info screen, I have an icon of a car with an exclamation point in it and it reads "problem". I have connected the OBDII reader to it and it does not have any codes. Nothing in the history, or in the current or pending. The car has full power and runs fine, but has the stupid RTOD.

I use a scangauge to monitor the traction battery in my 2001 prius. Today when I started the car to come home, the alarm triangle came on, but the scangauge shows no codes found. The car ran fine and got me home, but what the alarm is about.

I have a 2001 Prius with 150k on it. It has been giving me the triangle warning light and the car ! warning light. I can start the car and drive it, but sometimes when I press the accelerator the gas engine just dies and will not kick back in, unless I stop, turn off the car and restart it. (Issue seems to occur more in hot weather, could be a coincidence) When I start it the engine will run rough and shutter for less than a min, and then run normally.

Prius (2001-03) :: Warning Triangle / Hybrid System Icon Comes Up - Engine Goes Off
My wife has a '03 that has been great. No issues. I am a excellent mechanic, on conventional cars and motors. Here's my story:
Bought the car used and working last week. Put in a new 12v Group 26 battery w/conversion. I verified the 12v battery was at 12.8v and when engine was running, 13.6v to charge the battery. Car was starting and driving wonderful for about 600 miles. No shuttering, no shaky starts. Mileage was about 38.6. Anyway, yesterday was driving and all of a sudden the warning Triangle comes on, Hybrid system icon comes up and the engine goes off. I was able to drive the car about 1/2 mile on the traction battery back to my work.
It happened to have a code reader handy and it reads a P3125, Inverter. I realize there are sub codes that further diagnose the issue, but I don't have that type of OBDII reader although mine is a very expensive model. Anyway, I reset the code and got the car to start. Motor begins to go up in RPM and throws the code again. I shut it off, reset the code, try to start the car and I feel it slightly jump forward, engine does not start, then throws the warning code again. I did notice the traction battery is at 25%. I do this two more times trying to get the engine to start before I call the tow company. BTW, the car rolled easy, so I don't think its the MG2 is bad, although correct me if i'm wrong but doesn't Mg1 start the engine?
Oh, incidentally, also the ignition key does not release either. The key release solenoid is energized unless I unplug the 12v battery, then I can get my key out.
Prius (2001-03) :: Hybrid Battery Replacement - Warning Triangle Shown

View 3 RepliesPrius (2001-03) :: Red Triangle / Hybrid Warning And Check Engine Lights Illuminated
This afternoon, after driving about 150 miles, I came home and shut off my 2001 Prius. It was sitting for about 20 minutes before I turned it back on to drive off. Almost immediately, the hybrid warning light came on on the MFD, the red exclamation mark light illuminated, as well as the check engine light, and the motor shut off. I popped the hood, and could hear a high pitched squeal coming from near the inverter. I called my dealer to ask the service department what I should do, and they just told me to bring it in and they will take a look at it. I live over an hour away, so I don't want to bring it there if I can avoid it. I then shut it off and let it sit for a few hours.
After reading about the possibility of the auxiliary battery being bad, I went and turned the Prius on, and then shut it off several times to reset the hybrid warning light (I had to do so in order to access the aux battery information through the MFD). It turned on without incident, and shut off fine, and after being reset the hybrid warning light shut off, as well as the red triangle light. Then, I went through the process of pulling up the battery voltage information through the MFD.
With the car off, and the lights and fans off, the battery voltage read about 10.0-10.5 V. With the lights and fan on, the voltage dropped to about 9.5 V. After getting those readings, I drove it down the road a little ways, just going about 20 mph. It seemed to work fine. The check engine light is still illuminated. With the motor running, the voltage reading was 13.2 V, and then when I got back from my test drive and shut it off, the voltage hovered at 10.6 V with the lights and fan on.
Prius (2001-03) :: Steering Wheel Start To Violently Shake While Driving Got Warning Triangle
So I have come into ownership of a 2003 Prius and now I'm having issues with the power steering. I contacted Toyota and they told me the recal for the pinions was completed in 2012. Now own in the car I've noticed the steering wheel will start to violently shake and just last week while driving I got the warning triangle and the PS symbol and I lost all power steering. All this happened while driving on a highway. Toyota wanted to charge me 150 to diagnose the problem which I declined and took it to my well trusted mechanic. He told me the rac needs to replace. I've done a lot of research on this problem and have found many people complaining that even after having the recall done, they still had a problem and also were told the rac needs to be replaced.

I've been having issues with my beloved 2003 with a little over 130k with warning lights going on and off. I went to O'Reilly's they gave me the codes P3130 and P0303. One of codes states "misfiring on all cylinders," they didn't have a description for the other one.
Dealership won't tell me anything about what the codes mean. The warning lights are an exclamation point inside a triangle, check engine, and what looks like a thermometer in red.
Just got the oil changed a little over a week ago, dealership said they didn't notice any problems. Warning lights came back on last Thursday and just disappeared about an hour ago.

2005 with 123,000 miles. I have owned for a few thousand miles. Car was dealer maintained at every recommended interval. Car runs perfect.
After car sat for a week or so, I drove it and the red triangle popped up along with PROBLEM statement and take to immediately to dealer symbol. Red Triangle and other warnings repeats every once in awhile - will go a day without, and then will come on and off within a couple miles. Car continues to run fine. There are no other check engine lights. I have checked all the fluids and they are fine.
The battery charges fine, and holds the charge overnight. I have a generic code reader and there are no codes. I have read other posts, and there are always problems that seem to come with the Triangle. Gas mileage is fine as well.
Prius (2004-09) :: Red Triangle And Multiple OBD Error Codes
The red triangle warning on my dash recently came on so I am taking it to the nearest dealer on Monday. I think all of this is covered under recalls/warranty. Am I right?

View 19 RepliesPrius (2004-09) :: Death Triangle With Lots Of Codes Diagnosed
Upon turning on my car and driving a few feet I had the Red Triangle of Death, Yellow VSC, Yellow (!) Indicator, and check engine light and I'm trying to figure out where I should start working on the issue.
The Codes were as Follows:
P3000 (subcode 123)
C0200
C1241
C1300
C1310
C1259
A little history:
About 3 months ago I had an issue with the hybrid battery and replaced a battery cell which stopped all issues. About 2 weeks ago I replaced the coolant inverter pump and until today there has been no errors, CELs, or any negative performance.
This is a Gen II, 2007 prius with almost 200k miles.
Unfortunately I had plans that I could not reschedule and made the drive to the location and drove back. I had serious battery drain and it was almost always at 1 bar of battery, sometime reaching up to 2 bars. There is also the sound of a fan coming from the back seat, which I assume is the HV Battery fan, but it is on regardless of if I have air conditioning or not. A/C is working fine. When I returned home the battery charged almost up to full bars, but when I came to a stop the battery drained in about 10 seconds leaving me with very low power to keep moving. After that whenever I slowed down the teal arrows showing a recharge of the battery were gone and the battery seemed to refuse to recharge.
Steps taken so far:
I topped off my engine coolant in the front reservoir as it seemed a little low, but I didn't add much before it was full. The other reservoir near the engine was just about full and taking off the other cap showed coolant filled to the top.
I tested the 12v battery with my voltmeter which came back reading 12.7.
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) :: Red Warning Triangle Appearing Intermittently
Just this week the red warning triangle is appearing intermittently. I live over 200 miles from a dealer or Toyota certified shop- Light seems to come on only when I push the brakes moderately hard and is on for just a second then disappears- beeps when it comes on, too. I called the Toyota dealer and their answer is to "just bring it in"-- not able to "just bring it in" as it's again, 200+ miles away. One of the service reps said it might be low brake fluid- but the actual service tech said it was a failing ECU most probably - seems to be driving fine- should I be panicking about now?
