    So I went back out to the '08 silver loaded car this morning Open the door had no icon for the door being open and of course no combination meter initially no check engine light after turning the car back off and restarting now the check engine light is lit I rescan the codes I have the 1271 code for the combination meter stopped this is the second time in this car that this has happened with two completely separate combination meters I have many so now I will mark this one bad I have nine to go through I guess I should just leave the dash top off and sit the combination meter plastics and the plugs right on the open dash. The funny thing is is that my '09 which has had combination meter problem since I've bought the car and is magically stopped acting up in the last year never I could get the b1271 code never I have no codes on this machine except the converter which is always. So my take on this if I see the b1271 code I can pretty much be assured the combination meter has been detected by the body control module as stopped working.? If I don't see this code and the combination meter is not working be looking for some other reason why it's not working is what it looks like by the two vehicles that I am sitting here with right now which I own and never leave the property unless I'm in them does this sound plausible?

    Anything is possible, I guess.

    In all the posts I've read on this problem, some report B1271 and some don't. In almost all cases the problem is fixed by repairing the board. Sometimes it is not just the one capacitor that most replace. One of the situations where initially a person reports the swap did not fix the problem, upon further inspection it reveals that not all connectors were reconnected properly.

    I know that the Texas Hybrids repair process is to change three capacitors and one other chipset. That's why I recommend them over others.

    It is possible that the car you're endlessly rabbiting on about does have a different and unique problem. However, this is so rare I doubt you will get someone to tell you what they did to fix it. It is up to you to get off your nice person and trace the problem and get it sorted seeing as you have the testbed.

    Certainly, spilling your guts about it every 5 minutes on PC is not going to advance a resolution, and posting the same nonsense on everyone else's thread is just muddying the waters for those posters when 99% of the time their solution will be to replace the CM.

    Ordered one for this late 07 silver car today 200 something dollars plus $75 back shipping the old one back which I have boxes full of them. The '09 that I drive every day has been working flawlessly for the last year like I say if I push the start button and I don't see that check engine Amber light come on I push it again system is off and then push the brake in the start button again and the zero the check engine light all the ambers come on everything goes off just like it's supposed to there is something wrong there but I don't think it's anything to do with capacitors this is done this with every board I've used and there's no way every board I've had touched and comes through here is bad that's literally impossible the laws of numbers and whatever will not allow that to happen but we know what to do with that car and it almost never has to be done and we're at 400,000 miles and counting and running great so we leave that one alone that one is never had the 11:21 code this 07 is had that code since I picked it up in Raleigh North Carolina off the street and because of that I'm going to change the board because it is literally losing communication. But the funny thing is last night my idea was when I parked the car at the house I put a piece of tape over the trunk latch and I left the car off like I'm supposed to alarm not set but the rear hatch didn't latch so the little door open light has been on all night now I'm going to walk out there now and see if it's on. Okay so while sitting all night I just walked out to the car the door ajar light is still on and the car will boot right up to a display and I can't imagine that little LED has cost me more than a volt or two I'll check my voltage before I start the car.

    Did the definition of flawless change while I wasn't looking?

    It's pretty much working perfectly everyone who drives it can't make it do it It only happens to me about once a month and then like I say when I push the button and don't see the zero for the amber check engine light I just hit it again and then hit the break and do it again this is only at first start up once the car started in the morning everything is good but yeah other than that the car is flawless everything works perfectly the battery is great no drivability issues we just change the hubs it's dead quiet so yeah pretty much that's flawless to me for a 16 17-year-old car doesn't eat tires nothing now the 08 over there that's got the code of course it isn't flawless everything with that car is perfect as soon as I straighten out this stupid dash it's literally near perfect condition other than the exterior of the car is sun-eaten. And I'm not going to paint it to fix it interiors leather and clean as hell I will drive the you know what out of it getting about 47.

    We're talking about two cars here The one with the display messing up has been that way since I picked it up I had it working for 2 weeks and it just dies That's okay because I drive it without the display but this car has the code for the lost communication of the display out of the seven cars that I've owned I've never seen that code and I have the ability to see it in all seven cars with the machinery that we use this is the first time I've ever seen the combi meter has stopped communicating code. So I ordered what a combi meter it'll be here in a day or two All of the other cars the display will go out in the ones that it does there's no code for the combination meter stopped communicating so I have trouble believing that three capacitors are going to make that go away and the car doesn't even know it's doing it. And as it turns out the '09 that was given us this problem for the last two or three years pretty much is just stopped it's driven every day a couple hundred miles generally running service calls I can't remember the last time I got in it and had to hit the restart button again to make sure the display lit up has been a long time so as far as I'm concerned it's working everything is good. I'll find out when the new Combi meter gets here for this late 07 and we get shove it in and see what happens I expect it to work because I have the code the car knows the combi meter is not communicating but in my '09 that this has been going on and off on for 4 years now never had a code never not one time ever and we've had how many different displays in this car from 60,000 mi little old lady cars to 344,000 mi ride or die type cars every display has done the exact same thing there's no way all those displays have bad capacitors in Central North Carolina The numbers just aren't with that.
