Hi Guys, Sorry to start this off with a problem. I like to start a new forum with introductions first, but this is an issue wife is having out of town at the moment.
We have had issues with the electric switch on the rear hatch not working. Wife is currently unable to open the back, having to go through the back seat to get to the cargo area. This has happened before an a larger scale and we had to return it to the dealer to work out the issue. It took them several weeks to find the issue by replacing the Computer and the rear hatch switch itself.
We have had I happen a couple other times since and found those to be some programing issue. I found on a Fiat website there is a combination of things to do with the buttons on the key, or the ignition itself that resets the programming and fixes this issue.
I cant for the life of me remember the code, and Search here does not find it either. Can any one give me a clue to do this?


BTW, Promise I will fill I the intro later!

Sorry your having problems...1st things 1st though. Can you hear the hatch trying to open? If you can its likely just a piece of something caught in the mechanism...and from my experience it doesnt take much to make it inoperable. If that is the case some....enthusiastic tugging and pushing while activating the switch usually works...if not, sorry I dont know the code.

I'd take it in for warranty work whatever model car you got. Sounds like they didn't fix your issue in the first place

Welcome to the forum.

I have read of this on a few occasions and found it to be the switch in some cases and wiring in other cases. I do not recall reading of any "code" resolutions. I really wish I could help as I am sure your wife is not enjoying having to work around moving things right now.

Thanks for the help. Bit of background on this (will fill in profile with these details also).
We bought it used in Sept '13, its a Used '12 that had 35k on it at the time. We only had a warranty on this up to 50k and since we bought this for my wife to use for work, she hit that 50k real fast. So far I must say I am not real happy with Fiat's Customer Support or the Chrysler/Fiat Dealer that we bought this from. So far I have had issues with tires, rear cargo light x2, paint on sunroof and bumper, rear hatch x2, rear wheel bearings going bad and the latch that is continuing to act up.
We have the 500c Limited Edition, #17 of 500 produced. Its nice and has the 5 speed and plenty of options. I am not a fan of everything (including the interior lights) being tied into the computer though.
When the latch goes out, it does not operate the mechanism on the door itself. When this happened the first time, I noticed that when you went to push the button on the hatch, it was no moving part. The rubber bad felt "dead" like something was locked in place. They replaced the switch on that occasion. Later when I noticed it didn't work, I found that I could feel the button "push" like the keys on a keypad. This said, I started looking for what would make it move the latch itself. Checking online I found a forum that had several people with the same issues and the reset combination for the computer. I fit several forums to find that info and did not join or bookmark the site at the time. I think it may have been one of the European forums. I am going to do a bit more searching.
Anyway that reset with the remote cleared the trouble and we were able to open the cargo area.

Found some other sites that had basically the same fix:


I have had my 500c for about 6 weeks and the trunk/roof issue just happened to me too. Here is a step-by-step procedure for resolving this: (do these steps with the ignition on or the engine running, the car should be in park)
1) starting with the roof closed, hold the open button until the roof opens all the way (rear window down) plus 3 to 5 seconds
2) release the open button
3) hold the close button until the roof has closed all the way and keep the button pushed for 3 to 5 seconds
4) release the close button
5) the roof will open and then close to the sunroof position by itself (don't push any buttons while this is happening)
6) all is well; the roof opens/closes to its pre-set positions once again and the trunk can now be openned from the outside of the car.

------------------------------------------------------------------------------

I Found the answer in the August review by www.thetruthaboutcars.com. Here is how they corrected the condition: "hold the open switch for 3 seconds after the roof had fully opened, then close the roof and keep holding for 3 seconds after it had closed"

------------------------------------------------------------------------

To reset the trunk lock & convertible top:
Start with the top fully closed ... using the manual button (above the windshield) Hold the OPEN button till the top is fully open and continue to hold for at least 3 more seconds ... Release the OPEN button ... Hold the CLOSE button till the top is fully closed ... Continue to hold the CLOSE button until the top begins to fully cycle open then release the CLOSE button ... the top will fully cycle open and close at the 1/4 open setting ... This will confirm the relearn procedure was successful ... Auto OPEN/CLOSE and liftgate operation will now be functional ... Important do not interrupt the procedure ...


I will be trying this, and also working on an alternate latch system to use in case this continues ot be a problem,,

Well back in the shop again for the latch. Resetting did not help and couldn't get it open.. I took it to the dealer and was told that was a wiring issue, and NOT covered under the 1 year 10k mile repair warranty from them fixing the latch in September. I then told the rep that when it was in the shop in Sept, they had to trace ALL the wiring from the Latch to the computer. After the rep talked to the tech, she came back and said that they would fix it "This time".
Well they told me it needed a tire also, so I had them replace that. The tech tried the hatch again before pulling it out and it WOULDN'T OPEN AGAIN! They opened it up again and said needed a new latch so replaced that.
LOL, when I picked it up the next day, I got a warning light that the license plate light was ouot. I didn't even move the car in the lot, went back and got the rep, showed her and was told to bring it back Monday morning.

So, here I sit in the waiting room of Whitten Brothers Chrysler//Fiat waiting for them to repair my car yet again................

Pretty crazy, hopefully once done you won't be dealing with these type issues at all or for a really long time at least.

Sorry for the late entry, but didn't think to post this after getting wife's car back and hearing the news.
So, the rep comes back to me after 2 hours and tells me that the have the light working now. Found the issue to be corrosion on the terminals. Said the mechanic took it apart and was able to clean it best they could and put di-electric grease on it to hopefully keep it from going bad again. Said that terminals were in bad shape but working now. That was the good news. The bad news is that the terminal that is corroded has no replacement part for a "Fix". Said that if the corrosion came back, the only way to fix the connection was to replace it with a new wiring harness. Told me that the wiring harness itself would be a substantial cost... wait for it..... $2500..... and it would not be covered under any warranty. Mechanic said that Fiat has not made any parts to fix just the end connection so to repair it would be a total replace.
I tell you, I am rethinking the quality of the Fiat brand at this time.

Glad it is working for now and hope you don't begin to experience the same issues again, over $2K not counting labor and what damage could occur when being repaired, scary thought it breaking.

Bringing this one back to life. I have a 2013 500 Abarth cabrio. The trunk will not open from the outside. I have tried to reset the roof using the procedure, but either it's not resetting or i'm doing something wrong (most likely user error).

The enging is running, and starting with the roof closed, i hold the open button down.
The roof opens 3/4 to the expected stop point. At this point, still holding down the open button but the roof does not continue to fully open.
if I release and press again the roof continues to fully open.
Hold the button for 3-5 seconds, release, then hold the close button.
Roof starts to close, and stops at the first close point.
Continue to hold the close button but the roof will not move
release and press the close button, and roof continues to 2nd close point
if I continue to hold close button roof will not continue to close
release close button, press again and roof will close the final gap, fully closing. Hold the close button for 5 seconds and i hear the roof mechanism cycle. this will continue every 7-10 seconds or so. The roof does not ever open back up on it's own, to indicate the roof is completing the reset cycle

When the roof is fully open, and i try to open the trunk the roof will not move up, it's normal action.

From what I understand if the roof does not need to be reset the procedure won't work (what I am experiencing). Could this be the physical switch in the license plate light holder, the one covered with rubber? If the roof is working as designed, if the switch is bad then it's not signalling the roof to partially close, or to trigger the latch.

Thoughts?

Hi spharticus,

If you decide to visit your local studio for further diagnosis I'd be happy to follow up with them for you if needed. Just PM our page with your VIN and let me know!

Hi were you able to fix this issue? I was told it needs a new BCM and handle so after $1000 cdn I still have the same problem as you.

People with the hatch not working from the outside: It's a common problem, with the 500 and some other manufacturer's vehicles as well. On a high mileage car, it's often the wiring between the car body and the hatch. After a lot of cycles, the wires fatigue inside the harness where you can't see them. It can affect your hatch release, your rear wiper, your rear defroster, or the brake light. Or any combination of them.

On the 500, the wiring is not an easily replaceable sub harness. The only sensible fix is to open up the harness, and splice in repairs to the individual wires. You'll easily see the broken ones.

On mine, the rear defroster died and I lived with it. Then the wiper got erratic, and I lived with it. Finally the hatch wouldn't open, and that led me to fix it.

It's a pain in the neck job (trying to keep the language OK). Most of the wires on mine were either broke or there was only a strand or two intact. There are a ton of wires to splice. There isn't much room to work, and I was outdoors in my driveway (not having a garage). It took me the better part of an afternoon, and is one reason I don't own the car anymore. I can see why the stealers might charge 1000's to do it.
