Prius (Gen 2) :: Red Triangle / Beep On Sharp Left Turns - Error Code 505
Feb 26, 2013
Two issues are bugging my 04 Gen 2. The check engine light came on a while back, and the code I'm getting when I have it checked is 505, and I'm told it's the idle control system.But then I've been told that the Prius doesn't have an idle control system. At first it came on intermittently, and I noticed that when it was on the ICE did not turn off when sitting at a light or at low speeds, etc. It made sense to me that it might be something with the idle control, but I'm not an engine person. Now the light is on all the time. I haven't had the time to get to the dealer yet, but I suspect that's about to change, due to the next issue:
When making sharp left turns, I'm getting a very brief red triangle/beep/warning on the MFD that says "problem!". Sometimes it is so fast I don't even see the MFD warning.

I have a 2006 with 106K miles. Noticed after making a sharp left turn in a parking lot that the Red Triangle came on along with a beep and the message, "Problem" on the touch screen. Started happening more frequently either when the wheel is turning left or if I'm driving straight and the car drifts a little towards the left if I'm on the highway. Today it happened about 6 times. Warning goes off after a couple of seconds.

2004 PSD 4x4 72k. I thought I would be proactive so I bought the front ball joints and have plans to install them but recently I starting hearing (and feeling) a clicking sound in the front LEFT when I make sharp turns to the left and hit small bumps now and again. I jacked up the front end and am able to get 1/4" of movement front to back (top to bottom so not steering) in the wheel.
I narrowed it down to the hub. I took it apart and it is most likely a sealed unit so no adjustment is possible....that I can see.I pulled out the locking hub and got as far as I can to know there is not an adjustment. Need to confirm that it indeed is a sealed bearing and if so what are the part number(s) I may need to repair it.

I have a Toyota prius 2008 with 130,000 miles. I kept getting red triangle sign, the car will slow down and will need to pull over, shut it down and restart. I went to the dealer. First they diagnosed 12V battery issue, so we got that replaced. The red triangle sign kept coming, so we went to the dealer again, they replaced transmission fluid. They said it was low on transmission fluid. The red triangle sign kept coming. So we went to the dealer again. They said it is transaxle internal problem. The diagnostic code is P0A37. I have a couple questions. In California, what is the warranty for Transaxle problem. In some posts I saw 180,000 miles, 10 years. The dealer said they called Toyota and Toyota does not cover the repair. It is a costly repair. Second , is this code really requires Transaxle replacement.

I recently purchased a second-hand Prius T4 (2007 model) and I noticed that the red triangle exclamation was showing on the dashboard. Initially, my local mechanic found a P3000 error code and a B1801 error code.
I ran techstream on it just last night and the main errors that came out were:
Current codes:
Srs airbag B1801 - open circuit in driver side circuit
Air conditioner B1421
Transmission control - C2318
History codes:
HV battery - POA84
I also have just found out that this car was in a major collision in 2012. The air bag light is constantly on, along with the red triangle exclamation, on the dashboard. The fuses for the battery fan kit, horn, and air bag needed replacing (I think all three but definitely two of these).

I just bought a 2010 f150 and it came with the single button remote start. I've been reading lots of posts about remote start but none with my issue. Mine when you push the button the horn beeps, ignition comes on, the seat slides forward, then the horn beeps just one time again, and it just sits there with the radio playing and not running. Everyone else is getting a 3 beep error code and I'm getting just the one beep.

I was driving on the freeway when I hear a beep then the red triangle, brake, VSC, and check engine lights light up. It still ran well but whenever i step on the break a continuous beep comes on and the word "brake" comes on but disappears when I let go of the brake.

My 06 Prius with 130k miles just starting to briefly (1-2 seconds) show "PROBLEM" on the MFD and beep and sometimes show a red triangle.
This only happens when I am going down hill on a tight curve when going fast. This never happens going up hill (since I am generally going slower) nor on flat roads. Since this is my normal commute road and I have not changed the way I drive for several years, I am surprised that this is now occuring.
Some possible theories: oil is low - I will checksome level sensor is complaining? some tire rotation sensor is complaining?

I have one 2004 Hyundai Elantra. It was parked outside for almost a year without being used. I recently installed a new battery and had the front brakes/rotors replaced - they were rusted on so tight the guy had to partly saw them off. So now that I have set the scene, why this car turns off in sharp turns. Luckily this only happened twice as i was driving slowly and turning into my driveway. I can turn the ignition and it goes right back on.

So four lanes, divided, with a left turn lane, five lanes at the intersection. I'm down ~15 mph, maximum turn speed and one car is just clearing intersection and and +100 yards from next approaching slug of traffic. Keeping the speed, I make the left turn confident no problem then halfway through turn:
feels like a soft tuck
traction light flashes
already to straighten out
everything normal
This is the second time I've seen this in a year. Pavement dry, 48 hours since last rain; ~8:00 AM so rush hour is on. Before doing some parking lot tests, any clue about how to replicate?
My dashcam SD card did not play.

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...

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?

Last night I was driving home in my 2002 Prius, and the 'triangle of death' as you call it, went on. I got off the #405 and parked for 10 minutes while I read the manual which said get to a dealer as soon as possible. I started it back up and the engine seemed to be fine but the 'triangle of death' was still there, so I decided to continue to drive but stayed in the right lane.
I must have gone another 20 miles when I suddenly lost engine power, the headlights and dashboard were fine, and hazard lights worked fine. I was able to get to a safe place and towed the car home. Along with the 'triangle of death', the check engine light (little red icon) was on but I didn't get the 'Main Engine' error message.

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 noticed twice on the commute this morning that my vehicle made a long beep sound after completing a left turn. There were no other warning lights/messages on the dash. The first time, I thought it was something coming through over the radio, so I turned it off, and the sound continued, probably for a total of 6-7 seconds at least. It's similar to the beep that comes on if you start moving and the passenger is not wearing his/her seatbelt. The radio was totally off the rest of the way and it happened at the next left turn I made (when I got off the highway). Although it was icy this morning, it was not particularly slippery at the intersections when I made the turn and I did not notice the TCS coming on, etc.

2001 Prius
I was able to pull codes this evening ( no subcodes).
The codes are as follows:
P3000, Battery Control System Malfunction
P3030, Battery Voltage Detective Line Snapped
Will the P3030 cause a P3000 to pop up since it appears I have one of the 19 voltage detect lines corroded or broken?
Once I fix this issue, is there a chance that the P3000 will disappear?
I was just getting the triangle and the Main Battery error on the MFD up until yesterday. Yesterday, the ! with the car came on (Hybrid system) on the MFD. I did not check any codes until today. Car will currently not start at all.
Aux battery voltage is confirmed to be 12.3 volts via the MFD in the diagnostic mode so it's good to go.
No one around has a scan tool that will also pull the subcodes.

I'm rebuilding the traction battery on my 2006 Gen II Prius. When completed, I'd like to erase any "error codes" that should be erased (I don't even know where these might be), and turn off the red triangle of death, the VSC light, the (!) idiot light, the engine check light and the maintenance required light.

My partner's Prius is bring up the red warning triangle. She had a system diagnostic carried out, which brought up these two faults:
C1241 Low Battery Positive Voltage
C1300 ABU ECU Malfunction
The faults were reset, but it was only a short matter of time, before the red triangle appeared. My partner tells me this tends to happen more frequently when she is steering left and in colder weather.
She was advised the ABS ECU will need to replaced (it does says "new actuator" on the paperwork)

It was such a nice day today that I popped the Sunroof open on my shinny new 2013 Prius which I haven't had a chance to do until today. When I parked the Prius and opened the door to get out, I heard a 'single beep' sound. Confused and not knowing exactly what that 'single beep' was intended for, I proceeded out of the Prius and touched the button to lock the doors. But due to my absentmindedness, I then noticed that I had left the Sunroof 'OPEN'.
However, I couldn't believe that the doors actually locked and the Prius didn't do any other kind of additional alarming with the Sunroof left open. So, I presume that this 'one single beep' I heard when I opened the door was intended to inform me that the Sunroof was left open. It's a good thing that I wasn't in a hurry today and noticed it because I didn't know what that single beep was meant for.
