Problems with the dashlights and turning the car off

Google-Fu for "combination meter failure".

The "combination meter" is the big piece with the speedo and the idiot lights. There is a known defect and an extended warranty via Toyota for this exact problem.

 

You will know after you take the time to talk to your Toyota dealer.

 

Logically one wouldn't think so.......but I don't know.

Your symptoms sound very much like one of the batteries going bad.
Even new ones fail occasionally.

 

Here is the easy fix, ready?
Hold the start button down for ten long seconds (the hybrid system will turn off and the screen may or may not)
If the Screen stays lit:
Lift your foot off the break,
Then press the start button three times quickly, In less than two seconds(That will shut the rest of the car down and make all the locks work etc.)


iPhone ?

 

Totally bad advice.

There is nothing logical about your statement and clearly you don’t know, as you stated. One begs the question then, why offer advice on situation about which you know nothing? Especially when others who know more about this are offering advice/information.

Yes, this failure does cause problems turning the car off, and the solution is to hold the power button in for 3 secs until the car powers off. In post #6 Paul gives additional info for when the car powers off but the MFD stays on.

As others have said, it is the common combination meter fault and has nothing to do with the HV (hybrid vehicle) battery.

There is anecdotal evidence to suggest a relationship to changing the 12 V battery, but as yet, I have not read of an explanation of why removing power to the CM board causes or hastens the capacitors to fail. Perhaps one of the electronics gurus who frequent here could offer a theory.

As for a solution to the problem, if you can DIY, obtain repaired CM (with lifetime warranty) from Matt @Texas Hybrid Batteries for $150. This includes pre-programming the ODO with your current mileage. They will give you $75 for your old CM, if you return it to them. They are not the only company to offer this service, but they at a trusted and reasonable service.

If you are not the DIY type, you can still obtain a replacement unit from Matt, and have your local garage install it for you. It will still be way more economical than taking to Toyota.

 

You have all the symptoms of the combo meter blues. I recommend getting one from here:
Texas Prius Battery Replacement
He can program your mileage and vin into the new one. Lifetime warranty also.

 

It’s generally more than one cap. Plus you use a higher rated one, that was part of the problem. For your viewing pleasure:

I would not advise you to attempt to do your own repair if you have zero experience replacing capacitors at board level. Also as stated it is not just replacing one capacitor.

Your $150 ($225 - $75 – if you return your defective board to them) from Matt at Texas Hybrid batteries not only purchases a professionally repaired board – with lifetime warranty, but all the knowledge and skill of what needs to be done.

 

Not exactly. You send him 225. He sends you back 75 when he gets your old board back. Your cost is 150.

 

Sorry, about that, i've remembered the detail incorrectly. I'll change my original post.

Still good value at $150, in my opinion.

 

You ain’t lying. You can’t even get the meter adjusted at the dealer. They have to have someone else do it. Matt changes the mileage to correct and puts the correct vin number in it also.

 

If you can't get the CM to power up at all, talk to Matt to see if he can help. At worst you could send him you defective CM and he could repair it and send it back. It won't be as convenient as a swap bad for good, but at least it will solve your problem.

 

If the other member was able to tell you the specific fuse, then it would be simply a matter of pulling it and using an Ohmmeter to check the fuse for open circuit.

 

Combination meters don't fail outright, they take time to fail completely. I think yours will come back on eventually.

To help it along, people have tried turning on their headlights before starting the car. For some reason, this makes the CM turn on.

Another method people try is to disconnect the 12v negative for about a minute and the car resets. This often turns the CM back on temporarily

 

It was short and to the point.
It harmed no body.

YOUR rant, on the other hand was nasty and totally unnecessary.
