Prius (2004-09) :: Scanner Found Code U0293
Jul 13, 2016
Scanner found u0293,,,recommended reseal power inverter. what I have read for two days says its Power source ECU.. What happened,,,kids was driving car, had 3 phones plugged in, ac, lights, and when she tried to set cruise, car went into limp mode, gear lights flashing,,,went into neutral,,,stop beside highway,,had to be towed.
12 volt battery charged and tested ok. no blown fuses. I reset ECU by jumping pins 14 and 4. no change, tried master reset by holding brake and power button down, no change..removed ecu fuse to reset, no change.

I've been searching a way to read my check engine code WITHOUT a scanner (scan gauge etc...). I have a 2008 Prius and given that there is a lot of things that we CAN program just by presets, it would be surprising if there wasn't a way to read the error codes by some keypresses. Heck, in reality there should be a page on the MFD that just shows the error in english.

My Prius has started throwing the code P0A80, it all happened after I went away for work and left the car in storage for 15 days, during that time I left the OBD scanner plugged in and it drained the 12v battery, a quick jump start and it was back up and running.
While I was backing it out of the driveway the warning triangle came on and the MFD said "problem" the scanner showed the P0A80 code. I thought that was odd, but maybe related to the flat 12v battery and self discharge of the traction battery so I reset the code, it drove normally to the shops. When I restarted it and started to drive it threw the same code again.
I then installed techstream on my laptop to try and get some more in depth answers but was having trouble getting that running on Windows 8. So overnight I disconnected the 12v battery and would try again in the morning.
I got techstream working and connected it up to the car, connected the 12v and started it. While I was configuring techstream to graph the pack voltages I noticed something odd, the engine was being loaded and unloaded in 2 second cycles, and at the same time the inverter was whining as it does this. I was thinking maybe it's doing some sort of charge and measure cycle since the ECU's have lost any pack data due to the power loss of the 12v battery?
It ran like this for 20 mins or so and the engine stopped, techstream showed pretty normal cell voltages, I couldn't see any wild differences between the cells.

I was successfully able to install my Prius backup camera, but a few hours later I found that I could not shift out park. I was getting code U0293 on my scangauge. I can push the override button next to the shifter to shift out of park, but I can't figure out whats going on.

I have a 2005 prius and I got a scanguage to read the codes. I have two lights on my dash. One is the check engine and the other is the (O) light. I think this is something to do with the regen braking. Anyways when I run the scanguage it says no codes found. What type of scanner would be able to pull up all prius codes?

I have an 04 Silverado Z71. I am getting error code U1000 on my Scanner. As well as a torque converter code and a front axel code. I can not start the truck. Its as if its in a safety lock out or something.
I talked to a service tech at the lock gmc dealer and he said the U1000 code was definitely the reason it wont start. Possible bad ECM somewhere in the system.
Where can i find a full wiring schematic for my truck ?

My prius 2010 (III) accelerate much slower than before. I started noticing this after I picking up my car from the airport. Parked the car there for a week. I have the dealer checked the computer but no error codes found. My car has almost 250k KM on it. I have not replaced the spark plugs the last three years. Could it be the spark plugs?

The Prius has 115ooo miles. It is a 2005. Just recently it started showing the red triangle of death, check engine light, and the brake light. When I check for codes using a scanner it comes with the following:
P0A80
C1310
C1259
P3015

Looked around and could not find info on 2 codes. 2004 Prius : P0420 and U0293. One I believe is lost communication with hybrid system. Are these serious?

My 2005 Prius has 281,000 miles and is burning oil. No smoke or leakage just have to add oil between oil changes. I drive about 30,000 miles per year with my job. Car is paid for and I love not having a car payment, but fear this may be the beginning of the end.

My 2005 Prius is 161,000 miles old and I have only taken it to the dealership exclusively for service from the start.
Right before my last oil change the warning light (red triangle or with exclamation point) came on and the oil icon came on on the control panel. It would only come on when I pressed on the brakes. I finally pulled over outside an auto parts store and checked the dipstick. It was not showing any oil at all.
I went inside the store and put in three quarts. Took the car to the dealership the next day and they could not figure out why the car had apparently consumed so much oil. In fact, their scanning did not even show the warning light had ever come on.
Odd, since there were no leaks found. They changed the oil and told me to bring it back 1,000 miles later. Today, 1,000 miles later, I checked the dipstick and found that it shows only 1/4 full. When I last checked the dipstick, leaving the dealership, it showed close to full.

I have a 2005 Prius with 131k miles. The check engine light came on. I had my mechanic check for codes, he had 3different scanners. There were no codes posted. Next day light went off. It has been off for a week. Now it has returned.

This morning when I heard some knocking from the ICE and found NO oil on the dipstick. You wouldn't BELIEVE the drive the car did the day before when I lent it to my sister-in-law). Anyway, I thought the red triangle would illuminate with low oil. I can't seem to get the light to illuminate. Even when I first start the car and "all" indicators light up during the test. I'd say this is one important light. We've had the car less than a month and I could swear that when we first got it I saw the triangle at start up.

Up until my last oil change at 105,000 miles, I didn't notice any oil usage. When draining my oil, it didn't look like it was quite 4 quarts. After the oil change, I ensured that I had the engine exactly topped off to the upper mark on the dipstick. Around 600 miles later, I parked in the same location and have noticed that the oil level has dropped enough to notice. I am guessing that I will lose well over a quart between oil changes. Before I resign to the normal mechanical reasons (rings, cylinder wear, etc.)
The loss doesn't seem to be gradual which has me looking for other explanations. I also had a Toyota mechanic go over the car and replace the other fluids and filters at 100,000 miles (coincidence I think ).

I've got the hybrid battery out of the car and there is a decent amount of corrosion/acid on the copper contacts. I read that after cleaning them off with white vinegar and soaking in a baking soda/warm water mix... They spray some type of anti-corrosion spray on them.

Maybe I am running out of my beginner's luck. Recently when I did the second oil change at 10K miles, I placed the drain pan without taking into account the fact that the oil drains partially sideways. The oil stream ended up splashing off the edge of the drain pan and made a mess. Then I did not withdraw my hand fast enough when unscrewing the oil filter and allowed a stream of oil running down my arm and staining my new shirt. The I filled the new oil filter too full and had one more spill when installing it.
About two weeks later I found there was a very thin coat of oil at the bottom of the oil filter but no drips either on the filter or on the ground. I checked the oil level and it was the same as before. I checked the filter tightness with a torque wrench and it was also as tight as before. I wiped the bottom of the filter clean with paper towel. Now about another two weeks passed and a corner of the bottom of the filter is coated with oil again.
I am thinking maybe it was just the spilled oil gradually making its way from the (outside) top of the filter to the bottom? If there is a leak then I should get at least some drips, not just a thin film every two weeks, right? I also thought about untightening the filter and then tighten it again but I was afraid of large amount of oil coming out, would it? Also I had carefully checked the o-ring and wiped the flange clean before installing the filter and there are so many threads to screw the filter on - it is hard to imaging the filter would not seat correctly.

My 2005 Prius was working quite fine until few days ago when the dash lit up with ABS, Check Engine, red triangle, ((!)), and the red car symbol on MFD. Additionally, the hybrid battery fan now comes on once in a while. Mileage on car is 164K; changed the 12v and hybrid batteries at about 153K. Running it through codes scanners, the following codes were read off it:
* B1421 (Solar Circuit malfunction, passenger side. Also, AC malfunction [although on the car, the AC still seems to work fine])
* P3000 (Hybrid control fault, and cruise control error)
*C2318 (Low voltage error-power supply malfunction)
I have checked 12V status using the diagnostic mode this morning and found it to be 12.0V (although 2 days ago when I checked it was 11.8V.)
I have not used the car since as I wouldn't want it park up by the roadside. I'm scarred to think its the hybrid battery again... For now, the car still moves well. What should I check to confirm real cause(s) of all these?

My 1999 super duty v10 has thrown a code but my scanner and a mechanics scanner won't power up and read the code, I also noticed that the cigarette lighter is dead. Which fuse controls both the plug and the lighter?

I purchased a Gen I prius (non running) two years ago for a very low price and kept it in dry storage. At the time it threw a P3125 code on the ECROS scanner and would not start.
I finally have the non-running one in my own garage and am trying to get it running. The HV battery has been charged to 285 volts by a DC/DC converter I built. Last year the car would power up the ECROS OBD scanner and throw a P3125 code and I could hear the main HV Battery relay connect then disconnect. Now when trying to start it the 12 volt systems work, the OBD scanner from ECROS will not run, it has power, but no data - no OBD signal I guess, and no HV contactor noise either. I took the Vehicle ECU out from under the passenger carpet and replaced it with a good one from one of our daily drivers and still no OBD signal. I have checked all the fuses and no blown ones in any of the three fuse boxes. With the used Prius ECU in the daily driver, the OBD does work, the daily driver does not start, but no error codes.
Why does the OBD II not fire up the ECROS scanner in the broken Prius?
