Technical Boot won’t open

[Hellyea23]

Hi all.

Have a Fiat 500, 2016. The boot has been playing up. Googled and searched but can’t find the cure!

So the boot has been temperamental. You press the boot release button, you hear the mechanism go but doesn’t open. However every so often it will work and it opens!
When it doesn’t open I have to climb inside and press the latch to open.
However....

Also finding the rear wiper is being odd too. It sometimes moves slowly, then just stops in the middle.

Also sometimes when I put the rear wiper on the dash tells me the boot is open (it’s not). And also I get check number plate light warning on dash too.

Clearly an electrical fault?!

Help!! Anyone know what the issue is and how to fix??

TIA

Hi

SEARCH Maybelline. On here for the likely suspect

As above, do not leave this fault it's suspected that leaving the issue can damage other electrical systems in the car, not too hard to fix by a competent DIY person

Maybelline has thrown a hissy fit | FIAT 500 (2007+)

Well I suppose it had to happen sometime. Went to visit some friends for a couple of hours, got back in the car, and turned the key to find the dash lit up like a disco. :mad: Initial assessment is that I've got the orange warning triangle, flashing mileage, airbag & seatbelt 'do not drive'...

@Hellyea23

Have you checked the wiring yet?

Not yet, will be looking today at some point.

This applies to the Fiat 500c only. Before messing about with the wiring, locks, switches or anything else…

It took me 3 days of wading through videos and pages of posts from people who - like me - didn’t know that on the 500c, the car needs to know that the roof isn’t fully open. One post talks about a handshake between hood and boot and a software reset - which meant nothing to me and I wasn’t going to start muck around resetting the car’s computer that controls just about everything else too! So, in plain English… if the boot opens when the hood is fully back, it breaks the glass. When that sensor gets out of kilter, the boot stays firmly shut… just in case. The following - pressing 2 buttons - resets the sensor and - click! - the boot opens!

- Starting with the roof closed, hold the open button until the roof opens all the way over the rear window - plus an extra 5-ish seconds.

- Release the roof open button.

- Hold the close button until the roof has closed all the way and similarly, keep the button pushed for an extra 5 seconds or so.

- Release the close button.

The hood moves about on its own for a bit and finished up about a third open. Then that’s it… or at least I hope so - yours might be a different problem.

It's not really relevant to this thread but I've been posting this page from the 500C supplement for ten years now;

There are no sensors to tell the roof control module the position of the roof. If the module's memory is wiped, by disconnecting the battery or, in my case, a brief jamming of the roof on a foreign object, the module has to re-learn the limits of travel by the above procedure. If the module registers that the boot is open, or even unlatched, it will not allow the roof to fold down from the 'spoiler' position. The boot won't break the glass, which should be safely folded down flat on the shelf, but it could foul the folded fabric - you'll notice that if you press the boot release while the roof is fully folded it will not open till the roof has automatically returned to the spoiler position. Note: You can't affix anything to the rear glass, such as a rear-view camera, and should never place items on the rear shelf.

Well, thank you for clearing that up. No sensors at all to limit the extent of travel? Not so much as a microswitch? Must be magic.

OK so the glass won’t break. Seemed a logical thing to risk trying. Did anything I say materially affect the fundamentals of what I solution? Jesus! It fixed the damn thing and I might save someone ripping out wiring looms and all the rest.

This is why I don’t join forums. You might have been posting your little scan for 10 years but did you post that if the ‘module’ doesn’t correctly ‘register’ the good position (by magic apparently, that affects the boot opening circuit. Glad you know more than the rest of us.

I’m off to bin my registration.

Hi Id just like to add that in all the time i have been on the forum, any answers or responses to enquiry's or problems that you have posted have ALWAYS to me at least been done in such away as to try to help or inform the poster with a problem and in good spirt (and often humor).

I dont believe its in your nature or intent to belittle,obstruct, upset or hinder ANYONE!-Unfortunately sometimes when coloured by an unseen perception or influence the written word can be misinterpreted or miss construed and people can get a completely different meaning to what was intended which is what i think has happened here!.
This is a friendly self help forum,but by its limitations of being run and contributed too by failable human beings sometimes the wrong message or impression gets through!.
