Prius (Gen 2) :: 2006 Cells Replaced, Red Exclamation Mark / Check Engine Light Appeared
Oct 16, 2013
I just bought a 2006 prius. It had 2 bad cells in the battery pack. I replaced the cells and all seems to be well, they all read the same voltage and the car appears to be driving, charging, working.
I still have the red exclamation mark and check engine light. The only code I get says to replace hybrid battery pack.
There are no other specific codes or issues and it runs perfect. Basically I guess what I am asking is how to clear the light or figure out why the light is still on!

I've been using my prius 2008 very smoothly till today. It was 100F+ in Austin and very hot. The car, suddenly lit up all the warning lights: Engine, Red Exclamation, Hybrid, and brake lights. The brakes kept beeping on both sides. I also heard an engine noise that is quite uncommon for prius. I stopped the car in a parking lot.
I came back in an hour and tried to start the car. I only saw 2 lights now: Red Exclamation, and Engine check. It might some "click" noise when I started, and after that it was fine. I drove for a while and everything was fine but the 2 warning lights were still on. I tried starting and stopping few times. I did experience the clicks (1-2) and the engine noise. The engine noise lasted 15-30 seconds and then it was back to normal.
I followed the youtube video to look up the diagnostics (Display pressed + lights on/off 3 times) to check the 12V battery. It read 13.8 V. I recently had an oil change at Toyota dealership less than 500 miles back. So I am baffled at this point. I have about ~60K miles and it's a 2008 model. So if it's a hybrid battery issue, I am covered.

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."

I've got a 2009 Prius with 67k miles on it. The car has a salvage title, but has given me over 20k+ worry free miles. The past few days the car has been acting a bit odd (i'm not sure if these are related or not but I figured I'd just throw it out there as well).... The right front headlight has been on the fritz as well as the wireless door opener has been working sparsely (sometime it wont lock, sometimes it will). I just ran the test to make sure teh 12V battery was okay, and all of the voltages came back in the "normal" range.

Yesterday, started it up, began backing down the driveway, controlling speed with a little pressure on the brake. There was momentary weirdness, like the brakes had sort-of let go, then gripped again. And then got the warning "CHECK HYBRID SYSTEM" and a yellow triangle (inverted?) with exclamation mark.
I tried maybe 3 restarts, but the warning persisted. Phoned the dealership, booked-up Saturday, but they said they'd (commendably) squeeze it in. So we brought it in, when they eventually got to it they read the codes, cleared them, test drive, said it appeared the computer(s) "lost contact" momentarily, and it seemed ok.
I got in and started driving home, down the back lane first. Car started making a VERY strange buzzing sound, coming from under the hood. By the end of the lane I decided I better circle back to the dealership, pulled in at the curb in front, left it running and raised the hood, the hood support rod was loose, laying over the engine, doing a dance.

My check engine light came on, I took the car to my usual mechanic, and he said the codes returned indicated that two cells in the batter were bad. (I just called to get the codes, but he's out of the office for about 30 minutes on a test drive...)

Tested and replaced 2 bad battery cells in my 2007 Prius... Got everything put back together and now all dash lights are on and engine won't start... When i try to shift into drive or reverse it goes directly into park... I tested the battery without removing the safety key and the inside terminals are at 220 volts and the outside terminals are at 0 volts as shown by photo... Maybe due to a fuse somewhere?

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.

I have a 2009 Prius with about 38k miles. Lately I have been observing that the mpg is constantly dropping and has reached 38 now. For the past couple of weeks, I started noticing a weird noise as if something was rubbing against something else. The noise would come and go, as if something was trying to engage. Upon further experimentation I noticed that it was related to A/C - when the noise would happen, if I raised the temp enough to turn off the A/C the noise would stop. After that if I dropped the temp back, the noise wouldn't come back.
Anyway, today all of a sudden I noticed the A/C was not blowing cold air, so I was sure the A/C went down. However after sometime the car gave me red bang, and it says Problem on the screen with car sign and exclamation, and a check engine light. But the car drives just fine.

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.

I own a stock 2008 Prius.
My car didn't move for 1-2 months so I needed a boost this morning. I noticed there's the check engine light on and a red triangle.
Also, the car won't go on electric mode.

I have a 2002 Prius that needs work. The red triangle, PS, and check engine light are all on. It has these codes:
P3100 - 175 (HV ECU internal error. Motor Inverter Current Sensor Malfunction)
p3125 - 287 (Motor Inverter Finv. Inverter Internal Short)
c1259 (HV System Regenerative Malfunction)
I suspect the inverter or even worse the MG2 has burnt windings.
BTW the "infamous" inverter pump seems to be working. I can hear it and see the fluid in the reservoir move.
I suspect it is more a symptom than a problem and will disappear when the real problem is fixed.

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

My 2006 passat is showing an exclamation mark beside the cruise control symbol in the instrument panel. And sometimes it will work for 3 months and then sometimes it will cut in and out every day.
So far it has been on for 3 days straight. Anything I can check to see why it is doing this?
Also It worked for 3 months until I un-hooked my battery to install an amplifier and it started messing up the next day again.

For the past 3 days my warning light has come on. Just the exclamation mark....nothing else lights up...it flashed quickly then goes off. It seems to do this when I go around a corner. I thought nothing of it the first time it did this. However, today is the 3rd time it flashed. I have not gone out and checked that but I will. It is just strange that no other light comes on.

Today i had my front discs and pads changed on my 07 prius and after putting it all back correctly I went to drive the car and my abs , vsc and both exclamation marks where lit up , I've read that this is common and a quick reset on a diagnostic machine should shift them ? Is this correct ?

So I just got new pads and rotors for the front on my 2000 Mk IV, drove smoothly...
Then about 1 week in today, my ABS lights came on.
I turned it off, left it for about 2 hours then turned on the car again, Got a red exclamation mark that made 2 intermittent beeps together (twice), then the ABS light went off??
Still drives smoothly? faulty assembly?

I was driving on the freeway in houston yesterday and it was about 30 degrees. The low temperature light was on... Does it make a difference when it is cold? Why would there be a light to tell u that it is cold outside?
Anyways as I was driving on the freeway the red triangle with an exclamation mark came on and disappeared. Then a minute later it went on again and on the navi screen shows high coolant temperature symbol on it. But then it would turn off right away too so is this normal because I was kind of slowing down on the freeway and the book did say something but I don't think it was an excessive speed or anything.

So at about 147k miles, triangle comes on. It's the icon on the right with the car and exclam! mark through it. Turned off radio. listened to car and I could swear that it was running differently, but it might be in my head (I was kind of freaking). Drove to my Prius guy in the I.E. (20 miles) car seemed to act OK. Was using elec engine when needed and gas engine was fine. Was a bit shocked by how good the car was running but I was sure something sinister was happening and at any minute the car would melt. After 1.5 hours and a 20 mile test drive.
