Does Combo Meter REALLY need replacing?

    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).

    Dealer says its $800 to R&R the meter. If we don't get it fixed, how often do the malf's re-occur? We're in Florida, not a cold climate.

    Anybody NOT replaced the meter and continued to drive and drive and drive? Enquiring minds want to know.

    You get no speed or mileage data during the malfunction, i.e., miles traveled are not logged.

    Mine has done it twice during cool and/or wet mornings here in PHX. It's an '08, but since it's a salvage title, they won't honor the extended warranty.

    $800 is a pretty good price. Is that for replacement and reprogramming or a repair?

    might be worth inspecting solder joints on the MFD particularly around the plug sockets, it could be just dry joints, wont cost you anything to have a quick look.

    If you do find some bad joints but you aren't confident to solder them yourself I'm sure the local tv repair shop would hep you out for a small fee

    Well, as you may learn from other threads that yesterday, my 2009 Gen II (111,000 miles)started showing symptoms of what I subsequently find to be a fairly common problem, and even though later in the day the symptoms disappeared, and all the systems started behaving normally, so I was almost taken aback when I took it to the local dealer and they mentioned the warranty, offered to not only fix it under the warranty, but also provide me with a loaner for the duration at no cost (something about it being a safety-issue since the display (inc. the speedometer) was not functioning) - refreshing to find a dealer who will step up to the plate! :)

    He's talking about the combo meter - the speedo readout, green HUD, etc. It's an extended warranty item - 9 years.

    The response you received is per Toyota policy, not the choice of your individual dealer. They are obligated to do exactly that per the warranty extension letter.

    I have been through reflowing solder joints on the comb meter, it didn't help. I sent mine out to the guy that repairs them on eBay. It cost me $120 and was well worth it. I had it back within a week. He also sells repaired meters for about $150. He says the firmware on one of the processors is bad and causes stray messages to be sent on the CAN bus. They get worse over time. Mine got to the point where it wouldn't turn on at all.

    sorry my bad!

    must be a relatively simple repair if they are doing it for $120, looks like there is a few capacitors on that board!

    A couple of the caps do go bad, but evidently there is bad firmware on one of the chips. I took the opportunity to remove that god awful beeper on the meter. No more reverse beeping for me. No seat belt warning...it's nice.

    Reverse and seat belt beeps can be disabled using instructions on this site.

    I know they can be disabled. I don't care to have to redo it every time the 12v battery dies, that's all. He did the repair very quickly, I had the part back within a week. He also sells used repaired meters with varying mileage on them.

    Has anybody replaced a 2004/2005 combo meter with one from a 2006+ vehicle? That would fix the odometer limit problem and probably have better firmware. I just don't know if you could even plug it in...

    I haven't looked at the pinouts, but as long as CAN message are the same it should work. The ready light on newer gen 2 cars is on the idiot light board to the right of the comb meter. On the younger cars it is part of the meter. Any of the other idiot light empty spaces could be assigned as a ready light. I don't know how close the mounting is, general shape, etc... I was thinking that is what I would do at some point of the future. Honesty though, most of that I formation can be gotten from Torque and an Android tablet. I considered just mounting the tablet instead of the comb meter, but it also controls other functions, so that would be difficult. The meter would have to be left plugged in even if you were using a tablet for the display.

    I did this too and it worked fine. Tearing apart the dash took a couple of hours the first time, but it went back together in about a half hour. The biggest challenges, IMO, are removing the PS airbag and removing the A post trims around those airbags

    Yes. Those 1/4 window trim pieces are difficult to get out, and they have little tabs that slide into the dash. I drove my Prius for 2 weeks with all the electronics zip tied to the dash structure.
