Instrument Panel Problem with video!!! Joined: Oct 15, 15 1 0 Location: santa barbara Vehicle: Prius. I did try to figure this problem out by using search here and i did indeed found similar topics with same experience but noone seems to know what really causes the problem. This car is a prius at ,xxx miles on the clock with stock everything,original transmission and engine. Only routine maintanence done so far. It has a toplight and a taxi meter installed of course Here are my symptoms with the video.
When i start the car,the instrument panel speedometer,gear panel,fuel gauge does not light up. Putting the car in reversethe backup lights wont turn on and the back up camera wont work. It has a taxi meter and it gets signals from the transmission,it does not charge the right amount for the distance.
The instrument panel lights and all the rest comes back on and operates normally as they please. So i can not tell if there is anything wrong specifically somewhere.
The mechanic checked all the fuses and found nothing. I checked every possible connectors around the body where i can reach for something loose but everything seems to be good. Posting the video through this link on youtubehopefully someone could spot the problem and give me and others an advice who are having this problem. Got my fingers crossed. EZW1 Active Member. Does everything come back on when sitting still or while driving?
I suspect a loose connection somewhere. These can be a bugger to diagnose. Probably the easiest way for you or your mechanic is, when the problem returns, start wiggling every connector while checking the display. You'll know when you find it. It'll be working when the car is on and then when you turn it off and turn it back on. This problem happens out of the blue. It doesnt do this while driving. I mean when the dashboard lights are on when you start the car ,the lights will stay on till you turn the car off.
Very very weird problem.What the hell! The dash display cuts out completely which leaves you with no speed, fuel, odometer indications. The backup camera does not work and the car will not turn off or lock. After numerous searches and false leads that this was due to a low 12V battery I finally found the real problem.
The combination meter in the dash. It's a faulty part that Toyota knew was a problem and instead of doing a recall on it kicked out an extended warranty. I've been dealing with this problem randomly for over 2 years and finally just found the information about the combination meter.
I never received any information from Toyota about the extended warranty and they won't honor it because I'm 5 months past it now. This was after they told me it was warrantied and had me bring it in to get fixed. I told them to give me my car back and they lost a customer.
I took it to the dealership and I was told my battery wasn't holding a charge and it needed to be replaced. I did a self check of my battery and found the battery was holding a full charge and does not show any significant drain issues when lights are turned on.
I've been dealing with electrical issues since the water pump failure that caused the car to shut down in full drive on the freeway. Or at least that is the excuse given to me by Toyota.
The dealership won't take any steps until I change the battery because they say their equipment can't get a reading since my battery won't hold a charge. But when you use the check system within the car itself the battery is fine. The headlights have gone out AGAIN the other lights are blowing out, and the issue with the dash lights continue. This is an ongoing problem with this car, and the manufacturer does not want to deal with it. The dashboard lights went out, and car would not shut off, or lock.
I had to fill the car up so it would not run out of gas and keep it in a friends garage so it would not be stolen. Think long and hard about buying a toyota prius, as Toyota will not stand behind their car and its problems. There are other hybrids out there. This is the fifth time in one year the dashboard has gone out, I called the dealer twice and they told me it was just the weather. I did some research and for a limited time they were replacing these. However, I did not get contacted and I had been into two different dealerships, once for another recall and for a new 12 vlt battery.
They did not once mentioned the dashboard problem. We need to start a whole car recall on this Prius and a pain and suffering lawsuit as we all overpaid for this vehicle that is no better than a Pinto.
The Prius won't last another five years as the main battery is now going out and the dealer assures me that is not the problem, that would never happen. I just recently bought this Prius. It ran fine and the suddenly twice now the dashboard display cut out and the engine won't shut off. I am contacting the dealer today.
I bought he car "As is" from dealer so I may have to contact Toyota. Worst case scenario is a lawsuit because this is a serious and dangerous problem. Drove around and continued to turn off and it finally did turn off. Restart and dash back on. Update from Aug 28, : Mileage correction,It turns out the small battery is essential to running of all dash and etc.To completely fix your cluster, combination meter, instrument panel, speedometer, or dash that is going out and causing other issues such as not being able to turn off vehicle, unable to open trunk, backup camera not functioning, and forcing you to reset your Prius by unplugging the white harness by the battery terminal, which will only solve the issue temporary; follow the next steps to fix it completely and avoid paying hundreds of dollars for a simple solution.
Heads up! You will need to remove dash and solder a capacitor in back of the speedometer, which should be a piece of cake if you follow the steps below. Estimated time to complete the job is 1. Now you can either solder a uf 16v on top of the uf 16v or remove that it and replace it with a uf 16v capacitor.
I personally think it is easier to solder the uf 16v on top of that one. An example image of what I did shown below.
You can probably do a better job than I did, this is my second time doing this. According to some forums and videos found online this capacitor is the only thing that is different in the new speedometer, which is said to be too weak to hold the capacity.
Thanks for your post.
I was able to get my gauges working again by disconnecting the battery neg. Like Like. You are commenting using your WordPress. You are commenting using your Google account.

Feel free to comment below!It works fine during the daytime when the headlights aren't required. What could possibly be wrong? On the dash to the left of the steering wheel, near your left knee, is a little dimmer wheel.
You currently have it turned all the way down. Dialed all the way up past the click will give you "day mode" level brightness on the dash combination meter while you have your headlights on. Obviously, you have a North American Toyota Prius. Check the knob to where you can change the light intensity on the display. Sounds like it is either off, or turned down. Usually that switch is on the headlight, or a little knob the shows a gauge, with a pointer on it.
Answer Save. When the headlight switch is turned to the first or second clickstop, the brightness of the instrument cluster will be reduced slightly unless the instrument panel light control dial is turned fully on. Source s : I freaked out while driving my Prius when I noticed the combination meter out.
I quickly remembered the dimmer wheel, and all was well. On a Prius-owner's group, there was even one person who got a significant discount on a Prius from a used car dealer, because the combination meter was "off" and no-one had bothered to read the owner's manual to figure out how to turn the dial back up Jason 3 years ago Report.

Like Liked by 2 people. I removed the original capacitor and soldered a uf 16v capacitor onto the two silver pads that were there. The most time consuming part of the whole thing was taking the dash apart since mine had never been disassembled before. Like Like. The links to the capacitors in Amazon are discontinued. Any suggestions where the 22 capacitor can be purchased?
Thanks for the page. I followed the directions and I was able to complete the repair. It took me about 6 hours to get through everything, but well worth the time.
Appreciate the effort you and the youtube producer put in to help people. Thanks for taking the time to make this page. I should have probably just piggybacked a microfarad like you did, but a was what I had.
NHTSA — Electrical System: Instrument Panel Problems
I removed the original by using the soldering iron to heat up the positive and negative pad for the original capacitor and wiggling it off when each side became liquefied. I am not good at all at soldering, but I had a little luck or the divine guidance I prayed for on my side for about 45 seconds of relative competence.
After reading this, I sense we got royally screwed by the Toyota dealership mechanics. Could it be something else besides the capacitor? Hi Robert, I would still assume the uf capacitor is too low. Please share how it goes, this will help others as well.
Like Liked by 1 person. Thanks for the response.Three problems related to instrument panel have been reported for the Toyota Prius. The most recently reported issues are listed below.
The contact owns a Toyota Prius. While driving unknown speeds, the instrument cluster went dark and failed without warning.
The contact called a local dealer Toyota of redlands, new york st, redlands, CA and was informed to schedule a service appointment. The vehicle was not diagnosed or repaired. The manufacturer advised the contact that the vehicle was no longer under warranty and referred the manufacturer's legal department per the contact's request. The failure mileage wasNo one injured. Minor problem, but Toyota refuses suggestions "for legal reasons", so I have to report it to you, and hope that you will relay to Toyota.
Good car, good dash lighting system, nice rheostat to dim the instrument panel lights at night, to assist in night road visibility. The problem is that as you dim the instrument panel lights, the lighted symbol for the emergency flasher light switch goes completely dark before the instrument panel lights do.2004-2009 Toyota Prius no dash lights fix!
So, on a dark night, you dim the lights to make the instrument panel lights just bright enough to read, without excess reflection or distraction, and the emergency flasher switch becomes invisible because its light went completely out before the other instrument panel lights did. This increases distraction and reduces reaction time when you need to find and turn on the emergency flasher light switch.
I doubt this problem is limited to just my car. The simple solution everything seems simple to the guy not doing the work would be to design and wire the dash panel lights so that the emergency flasher switch light stays a little brighter than all the other lights, as they all dim. That way, the switch you might most need in a hurry will be visible, even if you have dimmed your instrument panel lights.
Quicker turn-on of the emergency flasher alerts following drivers sooner, increasing their safety, and mine. Thanks for working to keep us all safer on the road, and to improve the vehicles we drive. On a Prius gas gauge showed 2 bars and was driving across a bridge in California when the gas engine stopped. Looked at the gas gauge and it still showed 2 bars. Was fortunate enough to be on a section of the bridge with a breakdown lane.
The vsc, check engine, and hybrid system failure indicators where on - but not the low fuel!!!So how do you find out what problems are occurring?
