I have a Daihatsu Copen 2003 and the Automatic roof isn't going down? I have checked the boot and there's nothing in it, the flappy thing is properly in place and there's no water or rust anywhere. The two latches make the right beeping noise when I unclip them, and the red roof light comes on when I press the button to put the roof down but nothing happens. The back quarter windows don't go down and the roof doesn't come off and there is no beep. It's going to cost me lots of $$$$ to get an auto electrician to just look at it as I'm in a rural area, and I'm a student so I'm lucky if I can find enough money to buy two minute noodles so I'm really hoping theres a DIY solution or something that I haven't looked at yet that can help.
I'm not sure whether it could just be the fuse given that the beeps and red roof light come on but it would be an easy and simple check. Easiest way is to borrow a multimeter to check whether the fuse has blown. It's a 30A fuse in position number 1 in the main fuse box (which is the one in the cabin) assuming there's no difference between the .66 and 1.3 models.
Yes, the handbrake must be on as there is a roof-related sensor which knows when it isn't because you're not supposed to put the roof up or down while the car is moving.
Can i suggest check your battery make sure it is full charged at 14.2 volt i had a problem with roof And it was the battery not charged fully hope that may be the answer
I know you said the side ones don't but do the main windows come down? The windows and the roof are linked as well as the boot. Also does the boot close and open ok with the push of the button in the console? If any of those things aren't working the roof will not go down. There is a video around that a guy shows you how to reset the roof ECU and also to trouble shoot the fault codes. You need to short out two pins on the OBD2 connector which is just under the steering wheel to do the diagnostics. I used a paper clip. The blinking light will tell you in relation to how many times it blinks as to the fault it has. So once you know what the fault code is you can either fix it yourself or get someone to do it. If I can find the link, will post it. I have a copy of the fault codes somewhere I think. I bought mine with the roof and boot not working. It was a big risk but I got the price cheap accordingly and as I have been mucking around with cars for year I had a feeling I could sort it. I didn't bother with a Auto Electrician. When I reset the ECU the boot suddenly started working. After counting the blinks it showed there wasn't any power to the ECU. (13) The previous owner had spent heaps, bought a new ECU etc and still didn't work. Very expensive. It turned out to be a broken wire on the ECU plug, probably from them being to rough, but who knows? There is not much length in the wires so I couldn't replace it so I stripped it back and pushed it back into the plug and then put some Silicon inside the hole and job done with the cost of a paper clip.
Ok, got it. This link has another link on the page, to a You Tube video which is a must watch. The fault codes are on the page. Copen Roof Systems | Auto Electrician Congleton
I have a similar issue since my battery went dead a couple of weeks ago. Now my windows are intermittent and the roof does nothing at all. I've checked the fuse (ok), and have gone through the paper clip bridge process to clear the faults but they don't want to clear. Fault codes 81, 24 are showing. I cannot see what's wrong. Battery is 12.4v Any ideas would be very gratefully recieved. Mark
All hold! Found it. Didn't realise the luggage internal cover has a switch associated with it. If not in place the roof will not operate. How daft is that!
Its a pretty clever safety mechanism. However, it does not help if someone even more clever puts something on the retractable cover - it will be squished by the roof
