    That sounds like a great result. I guess humidity must have degraded the hydraulic fluid some how. Don’t get that in Hull !

    That's pretty bizarre; I really can't think of anything that can environmentally happen to hydraulic fluid that can make it just "not work". Unless maybe there was a little speck of dirt that was making a valve stick open; draining and replacing the fluid could have dislodged it. Grabbing at straws, I know. I have had zero trouble with my roof, and I put it up and down nearly every day.

    Getting back to the OBD issues for a minute, I will shout out to all other Aussie Copen owners that the Autophix JOBD reader is the ONLY thing I have ever found that actually communicates with the vehicle.

    All it told me was that there were no fault codes stored, which is certainly consistent with the MIL not being lit up. But it has never come on once in the year I've owned the car. I'm wondering if there's some non-damaging way I can trigger a real fault so I can unambiguously verify that this gadget actually works. How about if I disconnected an oxygen sensor or something like that?

    Anyway, the OBD function, at least in this version of the car, seems to be a subset which only addresses basic emission control issues. How you would go about interrogating the roof ECU, or any of the other subunits, I haven't got a clue. I've tried the shorting pins/blinking lights thing, and got nowhere.

    I did find an interesting forum regarding modding ECUs, but it was way over my head.

    Unplug the intake air temperature sensor or unplug the oxygen sensor? Easily reversible and definitely throws a code :D

    I have had problems with my roof not opening in the past and I have found that wiggling the wires under the handbrake is the first fix. I then had the roof light refusing to go off and the boot refusing to open (the interior was very wet). I took the ECU out of the boot and put it in the oven for a while on a low heat. I reconnected and it worked fine. recently my windows and roof would not work. I tried my wire wiggling then ECU removal (now on a radiator overnight), but foolishly locked myself out of the boot with it half open and half latched, before trying to put it back in. Thanks to this forum I found out how to get into the boot manually. Now all reassembled again, roof works perfectly, windows now work and boot locks as it should. Red roof light stays on all the time now, though. If anyone knows how to make it go out, let me know.

    I would be looking at making the boot watertight, before anything worse happens.

    Hello,
    I have had a look at previous forums but none quite fit the problem that I am having. I have 2004 Copen and the roof is up, but I can't close the trunk/boot. It will lower, the alto attic mechanism is operating, but just before boot closure, it pops back up. My son closed it rather forcefully a couple of days ago (groan!) and I wonder if this is the problem. I would love any tips or advice.
    Thanks,
    Narisha

    I found another person who had what sounds like the same problem, they fixed it by adjusting the boot hinge brackets which were slightly out of alignment. No instructions how to align them in the thread, just says a Daihatsu garage showed them how to. That seems the most likely problem, your son knocked something a little out of whack, if you can figure out what and put it back where it should be...

    Thank you so much. I'm going to have a look at that now. Cheers!

    Oh wow. I didn't know I could just paste a full translated bit including the pics. Japanese owner took 3 seconds off his opening time by changing the hydraulic fluid and another 5 by lubricating the mechanism.

    I've been dreading something like that happening; thinking about slamming it shut hard makes me cringe. There are no Daihatsu dealers/garages in this country anymore, thanks to Toyota. If it's making all the right whirrs and clicks and then it pops back up, then it sounds pretty sure that one of the latches has gone out of adjustment. There is very little good information about this delicate mechanism, at least that I've been able to find, but it's possible that the ECU has got itself in a knot. You can reset it by disconnecting the battery for about 10 minutes. I got a fright the other day when my roof wouldn't latch in place, but it turned out that the car wasn't level, which was apparently twisting the body. This kind of thing could affect the boot lid as well, so it's worth investigating.

    There's still kind of one - these are Toyota now but they're still also an official outpost of Daihatsu.

    My roof opened very slowly, I had air in the oil (it is not allowed to open the roof as the car is standing upwards) I have cleared the system by getting rid of the air and it is ok
    Add oil to the system

    Thanks so much for your response. I had to replace the clutch cable the other day, and I am fortunate to have a lovely mechanic. He had previous tried to recondition it (clutch cable) but when it failed, I ordered a new one from the UK. It arrived and he fit it for me at no charge. Amazing hey? Anyway, one of the guys in his workshop spent an hour and a half having a careful look at the boot. He couldn't fix it then (again no charge!) but wants me to bring it back so he can have another look. I will bring your information when I do. I am devastated because my beautiful little car is now sitting idle because I can't close the damn boot! I am terrified that it will end up costing me a fortune to fix because the roof mechanism is so sophisticated, it's like trying to find a needle in a hay stack. I will keep you posted. Thanks for your interest!

    Thanks for this. I will call them on Monday for advice. They are 3500km from me but may be able to help me or my mechanic.

    So I've tried disconnecting the batter. Unfortunately it's nor resolved. My neighbour who is a retired aeroplane engineer had a quick look and suggested the button in

    Inside the console may be the source of the error or possibly one of the micros switches/sensors. It's beyond me I'm afraid. I'll speak to Toyota Australia on Monday and will probably get my mechanic to have another look. It's so frustrating as I have loved the car until now. 2 years and not a hitch, but I have to fix it because i can't use it or sell it in its current state!

    I'd try to remove the boot release switch from the center console and disconnect the wires in case its just a faulty switch.

    The other place it is trigger by is the remote receiver, if you hold the unlock remote button down for a while the boot unlocks. Not sure where that is but try and find it and disconnect it too.

    Hiya Dominic, my apologies for not checking back... the reconditioned roof motor worked like a dream, but am facing the same problem now abt 1.5 yrs later. :)

    I've only used the car a couple of times since but already the roof struggled to close again and I had to put my hand under the roof and help it along.
