Prius V :: ECM Malfunctioning - Blown Fuses
Mar 10, 2015
A dealership is attempting to charge me several hundred dollars to replace blown fuses that they claim is a result of an overpowered attempt at charging a seemingly dead 12V battery. The interesting part is that after also replacing the air/fuel ratio sensor (which they initially claimed was the cause of a check engine light even after replacing the fuses) Toyota is telling them that the ECM should be replaced in order to extinguish the check engine indicator.

My cousin's 2009 Prius won't start and jump starting did nothing for them. In fact, when they tried it, they got sparks when they hooked up the ground cable and the headlights came on and stayed on the entire time they were attempting to jump it. Try again, and same thing but now I know they didn't go about it incorrectly or anything. There are also at least three blown fuses, I believe she said they corresponded to the smart key system, electronic throttle control (both up front) and then one in the trunk for the hybrid system.

We have a fleet of Prius's with 11k miles on them. Windshield wipers don't work and cigarette lighter plugs don't work. I'm guessing this is due to blown fuses. Where the fusebox is? I'm getting fed up with this. Also, is there a diagram somewhere that shows which fuses are for which circuits? (IE Which number fuses protects windshield wiper circuit) so I can finally see in the rain...

My fog lights were working perfectly but I got the dumb idea that I wanted to turn them yellow. I bought some Hella Yellowstar 55w bulbs and installed them. Fogs worked for a couple of hours then I noticed that they wouldn't turn on. I replaced the 15A fuse and once again it worked fine for a couple of hours before I blew another fuse. Now every time I replace the fuse it blows as soon as I switch the fogs on. Was I correct in thinking that 55w was the wattage of the stock lights? Also I understand that you're not supposed to touch the bulb itself as oil on your fingers will heat up once the light is on and cause this problem. Tomorrow I am going to reinstall the stock bulbs and replace the fuse again and see if they work.

This morning everything worked on a 1999 Suburban 4x4. One hour later, my blinkers (turn signals) were not working. Flashers were.
I checked the fuse (fuse 16) for the turning signals - blown. I bought some fuses - replaced turn signal fuse. It blew immediately and then the hazards no longer worked. I replaced that fuse and the hazards lasted a few seconds.
Hazards & brake lights are on the same fuse (fuse 1) so I am left with no brake lights, hazards or turn signals - I am an accident waiting to happen!
I switched my cigarette lighter fuse for the hazards/brake light fuse - didn't start the car - and turned on the hazards. I heard the fuse blow immediately.
My husband put a new radio in last year at this time and has fog lights wired to it - but that was last year not last week...
I know trailer lights are attached to fuse 16 (turn signals). I bought this car used, but it does have a trailer hitch with wires that I have never used.
Where to even start looking for the short... a short that would cause the hazards/brake lights to short out also.

I have a '95 Camry LE with the 2.2L four cylinder. The car ran PERFECT. Went to town today, great. Get in it a few hours after returning, it will turn over but not start. It is getting fuel, no fuses are blown, but is not getting fire.

4 days ago, my '04 Chevy Aveo (89,300 miles) would not shift out of park and no brake lights were coming on. I had to use the shift lock release to start the car in neutral, and I took it to dealer. Dealer replaced the brake switch. One day later, the problem returned. I took back to dealer, and they showed me that the light blue "15" stop fuse (the right column of fuses, second one down) had blown. They replaced. It again worked for a day, and the problem came back. Each time I put a new 15 fuse in now, it works temporarily, but now fries either immediately or within an hour. In order to drive, I still have to use the shift lock release, which isn't great, because it means I have to drive without brake lights.

I have a 2010 Toyota Camry 2.5L. Suddenly the blower-motor stopped working. I looked at the under-hood fuse panel and noticed a few of the fuses in the fuse bus-bar were blown, however I'm not sure how the bus-bar is removed. Is this most likely my blower-motor problem? If so, how do I replace those fuses?

A couple years ago my car got stuck in Park, in which I had discovered my brake lights and a few other electrical fuses blew at the same time. It has happened randomly about 4-5 other times since, in which I take it back to the dealership and they "fix it" temporarily. After about a 1 1/2 years of no trouble, it happened again, and the dealership traced it back to the GEM module, which they replaced for me. Electrical components I forgot I had (like automatic locking doors) came back- for about a week. I got stuck in Park again, lost my break lights, as well as some other functions. I haven't noticed this problem on the focus with other discussions. Now it has added to much time in the shop, multiple FORD dealerships unable to fix it properly, and lots of wasted money. Shouldn't a new electrical unit fix the problem?

Driving home tonight...noticed SOC was PINK...2 to 1 bars. First thought was the HV FAN...!
I JUST did the HV fan maintenance the other day and I'm certain I buttoned everything back up correctly..... There are only 2 connections to the fan that I unhooked and then rehooked back up...... I'll re-open tomorrow to check for loose connections.
Is this symptomatic of the fan not working? and Is there any way I can test the fan?
I've driven the car for about 200 miles in the 4 days since the maintenance but I rarely keep eye on SOC so I'm not certain what it's been reporting thru that period...Just looked tonight for some reason. Maintenance light has been on for awhile before I performed this ....but I'm guessing that's just Oil change needing to be done.

Our 2010's NAV head has recently begun throwing fits. Sometimes it's hard to get it into route planning mode via the touch panel. But, what's more prevalent is when the "hard" buttons are pressed the unit does other things, most often, for example, is that the "map" or other hard button is pressed and instead of the screen going where it's supposed to it'll switch radio stations.
Nothing foreign has been spilled, stuffed, or crammed into it. The car is garaged. Any way to do a hard reset?

The other day my CD player in my 04 Prius (130k miles) started malfunctioning.
When I made sharp turn, it tried to eject a CD - and kept trying, turning the radio off. Then a couple of fuses blew and the entire display went off, fuel indicator in dashboard stopped working, and VSC light came on. The dealer replaced the fuses, but they promptly blew again before I left the parking lot. And the speakers stopped working.
07-09 Radio (with Aux Jack) in 04-06 Prius?

I think my tire pressure warning light is malfunctioning. I check all the tires with different tire gauges and they are all showing around 40 psi. I reset the system by holding down the button and let the light flash 3 times after I check them. It is only sporadic and does not stay on unless one of the tires is low. I did have a loose valve stem, that I tightened myself. When it does this it seems to come on and flash before going off and does not stay on. Sometimes it stays on for a little while and then goes off. Could it be a bad sensor?

2006 Prius, 114K miles. In the last week started getting the intermittent warning of "There is a problem with the parking transmission lock. Place the car on a flat surface and fully set the parking brake." Car would not start, would only go into neutral. All accessories work fine, seems to be plenty of 12V power. Did a lot of research and determined that the most likely cause was a failing 12V battery. Used the diagnostic mode to check voltages, had 12.1 at "READY", 11.6 under auxiliary loads, and 14.1 with engine on (I did get the car to start eventually but can't figure out how and under what set of circumstances it would start).
So I ordered a 12V battery and replaced it. After replacing, I still had the Hybrid warning light, but after stopping and starting the car 3 times it went away. Car worked fine for a day but now the intermittent warning has returned. With the warning on, the parking lock seems to be fully engaged (car won't roll even on a slope).

We've got a 2005 with 110K miles on it and recently the Combo Meter malf'd -- in the space of a couple days, the car didn't want to shut off twice, and once at start-up the instrument panel didn't light up. Since then it has run just fine. Took it to the dealer and they want to replace the combo meter. We never got the "Warranty Enhancement" notice (which has, of course, expired).

Within the week the head unit has started to glitch out. Doesn't seem to be any real issues with any usability- at least yet. I have a 2011 Prius II.

I was out of town for about a week. I drive a 2008 Prius with about 35k miles and no previous issues. I get back tonight and go to open the door with keyless entry. Nothing, doors wont open. I hadn't replaced the batteries in the remote since I bought it, so I figured it was just that. I use the key to manually open the doors. I then go to start the car. Nothing. No lights, no noises, literally nothing happens. I figure, perhaps I left a light on while I was away and the 12V battery is drained. It is quite the rare thing, but it has happened a few times in the past. Usually I would catch it the next day and be ok, so maybe a light was on for a week and that did it.
So at this point I assume it's just a dead 12 V battery. I ask my friend to give me a jump. We open the hood, connect up the jumper cables in this order : + Prius, + and - to his battery, then - to the Prius frame. Quite a few sparks fly, which seemed like more than what I was used to seeing, but it doesn't seem too outrageous. I try to start the car and nothing happens. My friend then tells me he accidentally hooked up the jumper cables backwards. (I know now this is bad, and may be the source of the problem but hear the rest of the story to get a complete picture of what's going on).
So we swap them on his battery and try again. I put my foot on the break and push the power button. His car is still running in the background. The power button LED then turns green, and that is it. No noise or anything else. I then (while keeping my foot on the break still), push the power button again. This time the power button LED turns orange, the parking break P LED turns on green and the check engine light on the dash turns on. Also I think the car also makes the normal humming sound we are used to hearing when it turns on. No other lights are on at this point. The main display doesn't come on, nor does the interior lights work, or anything else for that matter.
The only thing functioning from inside are those 3 lights. I turn the car off and we just figure it needs more time to charge. So we give it a few more minutes of charging and still the same thing. We notice a strange thing. We hear a clicking sound coming from the fuse box area of the car. Every 5 seconds or so, it sounds like a relay clicks, and then clicks off after 2 seconds or so, and this continues on. My friends engine sounds as if during those two seconds like it is sending current to my car (lower engine rpm). So it sounds as if the relay sends current somewhere for a few seconds and then no current goes to my car, 5 seconds later it sends current to my car then 2 seconds later no current, etc. This goes on continuously and we are not sure why.
We figure maybe a fuse is blown. My friend checks the fuses we think to check but can't seems to find anything wrong there. We then think maybe the power needs to be disconnected to the electronics to allow capacitors and what not to discharge. So we disconnect the lug from the jumping terminal (the one we connected the + jumper cable under the hood) for about 10 minutes. We reconnect the lug back 10 minutes later and try again. Same things with the lights and buttons pushing as before. The only difference this time is you can get these lights to turn on without having the jumper cables connected (as if some of the battery was charged).
Next we figure, maybe we just need to hook directly to the 12V battery in the "trunk". So we connect to that. Now, instead of having the relay tripping every few seconds we don't hear the relay tripping at all. And the engine rmps are operating constantly as if it is consistently drawing current (constantly lower rmp sounds). So that is different this time than when we connected to the post under the hood. So we continue running the car at high rmps for a few minutes and try again. Still the exact same thing with the lights.
Also during these tests the break pedal seems to put pressure on itself when you hit the power button a second time and the lights turn on. (This is just a detail to include, I'm not sure if there is anything useful to gain from knowing this). Anyway, I know the problem is most likely that everything was fine until my friend accidentally hooked his end of the jumper cables to his battery. But in the event that there is something else I should check.

Owner's manual says under the steering wheel but I don't see a compartment anywhere (the center console outlet is dead; I assume it's a fuse).

So I bought two new HID bulbs for my 2007 prius. Mostly it had been the left one that turned off after a while. So i put a new bulb in and it goes out after about 10 seconds. So i put the other new bulb in and it goes out after 10 seconds too.
