Technical 500c wont close roof

[NickiR]

Hi,
I have just bought an 2010 Fiat 500c
The convertible top is bot working as i should, maybe some of you know the problem?

When i open i work fine. But when i close from fully open position, it only lifts 2-5cm then go down again. The only way to close it, is to help it come up by hand while pressing the button.
As soon as it goes to the first stop after full close, it can close by it self.

I have tried the reset seequence, but when i hold the open button in, the roof stops at the step before fully open and nothing happens before i press it again.

Can anyone help?

I haven't heard of that before. It suggests perhaps there is some resistance to the initial movement if It moves past that point with help from you. That's the point at which the roof leading edge flips forward to lie parallel to the track as well. It might help to apply a lubricant to the track in that area and see if it makes any difference. Are both sides aligned with one another as they start to move?

When the roof is fully down, i.e. hanging over the boot, and you press the boot release, does the same thing happen?

I havent tried to open the boot when the top is down.
Is it becuse you are thnking that it could be a syncro problem beetween the boot an top?
The boot handle is not working only the Remote at the moment.

It seemes to be alligned when it tryes to close. I did also try to lube it, but at the buttom where the problem is, it is very hare to get to becuse i folds in that area

You can close the roof manually by using the wheel brace (or better still, a rachet socket) on the nut at the top inside of the boot (see photo) but I'm not sure how that would help.

The boot lid and the roof are interlinked so if you have a problem opening the boot I'd suggest you get that investigated first. When it's working correctly you cannot open the roof past the 'spoiler' position (see other photo) while the boot is open/unlatched - that is, it will not fold down over the boot lid. If it is fully down, pressing the boot release on the remote, or on the handle, should cause the roof to automatically move back up to the spoiler position before unlatching the boot lid. The fact that you say it stops at the spoiler position when you try to use the initialization procedure might be connected. When you start the car do you get a brief message that the boot lid is open?

You will probably need to check the wiring from the body to the boot lid. A 2010 car will have the short cable and it's prone to breakage, especially where it gets stretched over the edge of the boot when open - this is a common fault. Check the number-plate lights are working and that the boot light comes on when the boot is open (it’s such a feeble light you may not notice when it doesn’t work – I didn’t!). Once you've eliminated these test the roof initialization again and take it from there. You may also have to check the micro-switch in the boot handle.

I Will start to adress the boot then, it will only open by Remote and the light is not working.
I just thought that when the roof would open, but not close the problem should be elsewhere.
Its at the mechanic now for some other repairs, when i get it back i can check the things.

Thanks so far for the inputs it very helpful

The fault might indeed be elsewhere of course. On this forum roof faults have been fairly few and far between. My 2013 car has the roof open at least 80% of the time that the car's on the road and I couldn't guess how many cycles it's been through in 8.5 years!

As I understand it, the roof controller module, which lives next to the motor on the rear shelf, is independent of the body computer but does connect to it to get information such as open boot and speed. You can open/close the top to the spoiler position at up to 100kph and the drop to fully open at up to 80kph. Beyond these speeds it simply ignores any button pressing. With most convertibles you have to be stopped or nearly stopped.

I still have the user manual supplement for the 500C and would be happy to scan it for you if required - it's only a few pages.

Merry Christmas!

 

[NickiR]

It could be great to have the supplement, i only have the normal manuel.

I Will try to go through the different suggestions when the car is back. At the moment i am waiting for a new cable for the rear boot. Its stuck in the mail. Maybe i Will solve some of the things.

The thing i find wierd is that i Can open an close it by Holding the button. And then when close from fully open it is like it gives up after few centimeters moving.
That foult Can i not find any other that have experienced.

Thanks again for the great tips. Hope the mechanic will be finish soon with the shock absorbers so i Can get it back and trouble shoot.

Merry Christmas

Sent the supplement to you.

Just to clarify for my benefit; when you open or close the roof I presume you're holding the open (or close) button down for the full time. Are you also holding the 'close' button down when raising the roof from the fully open position? If so have you tried to raise it with just a short press of the 'close' button?

 

[NickiR]

As i remember it Will go back at least the 2 first step automatic just with ind push. I am in doubt about the last step all the Way down.

As i also remember it Will try to close from fully open with one push, but very fast go back down. Then with some luck and helping the roof togheter with pushing the button it close to the next step. And from Thers i Think it Can go by auto to close

 

[Piccolo Nero e Bella]

Right.

If you check "Conversations" above, next to your login, you should be able to see my message with the pdf attached.

 

[NickiR]

I have found the dokuments thanks.

Just got word from the mechanic that the boot handle i toasted så it Will nede a new one. Maybe its Connected to the roof problem.
The wire to the boot was fine.

Where Can i find the oem nummer om such a part?

 

[Piccolo Nero e Bella]

Can't tell you the part number, even though I've had mine replaced twice it was under warranty so there's nowt on the paperwork. A dealer should be able to tell you.

 

[NickiR]

I got the car back with a new boot handle, and the mechanic Said he would suggest to look at the roof later when temp is better. Its snow and rain all the time now.

But somehow the top is actully working an Can lift from fully open position now.
The only thing i cant do is to get it to reset.
When i hold the open button in, it stops at spoiler position and dont go further.

Any ide to what i Can do?

That's good news. When you open the roof normally (with a single short press of the 'open' button) it should stop at the spoiler position and a second short press of the button should lower it completely - then a short press of the 'close' button should return it to the spoiler position and a second press move it to about 250mm short of the front, from where you close it completely by holding the 'close' button in. Is this what happens?

Ahoj,
Práve som si kúpil Fiat 500c z roku 2010
Kabriolet funguje ako má, možno niektorí z vás poznajú problém?

Keď otvorím, fungujem dobre. Ale keď zatvorím z úplne otvorenej polohy, zdvihne sa iba 2-5 cm a potom opäť klesne. Jediný spôsob, ako ho zavrieť, je pomôcť mu zdvihnúť ho rukou pri stlačení tlačidla.
Hneď ako po úplnom zatvorení prejde na prvú zastávku, môže sa sám zavrieť.

Skúsil som postupnosť resetovania, ale keď podržím tlačidlo otvorenia stlačené, strecha sa pred úplným otvorením zastaví na kroku a nič sa nestane, kým ju znova stlačím.

Môže niekto pomôcť?

Ahoj

Ako riešite tento problém, prosím? Mám to isté (káble a ostatné vyzerajú v poriadku)

Mn thanks
