Boot open / closed sensor location?
« on: January 17, 2013, 12:12:55 pm »
Before I completely fall out of love with my car.... Anyone no where the sensor is that tells the dash to report that the boot is open on a 500?

Boot is shut, but when driving along I get the warning light and message on my dash telling me that it's open.  Stopping and opening & re-closing sometimes solves the issue.  But it can come on when I've not even opened the boot and go over a speed bump / bump in the road.

Any help appreciated.  Car is out of warranty so cost will come to me if it's really, really broken.

    I believe the sensor is in the latch mechanism itself. If that isn't the problem I know that a few people had had problems with the wiring loom at the point where it passes through the rubber grommet between the body and the tailgate.

    Apparently, the wires inside the loom start to break as a result of the continual opening and shutting of the tailgate. This is the first time that I have heard of it causing this particular problem, usually it affects the rear washer and/or rear wiper function.

    Cheers for the response.  I'll check the wiring and i'll also have the mechanism off to see if I can see any issue.

    I've seen a replacement mechanism on eBay for £30 so might just divvy up on that and switch them to see if it solves the problem.

    Little update.  I've replaced the boot locking mechanism (£28 from Fiat) and now the car constantly tells me that the boot is open.

    And now upon locking the car the indicators flash 9 times (really quickly).  The car locks up fine and the doors nor boot will open. But obviously something isn't right.

    Any ideas anyone  ???

    there are 2 different 500 boot locks, have you got the right one?, part number should be 55702917, the other one is for cars without central locking :thumb:

    I'll check, but the boot deffo works off of the central locking no problems at all.

    Check the wires that go from the body to the boot, they are prone to rub on the car body and cut through the wires.
    You need to pull off the rubber to see the wires.
    I bet thats what is making this happen.

    Had the same problem, car was still under waranty. The dealer changed the switch, the schrome boot handle and then finally found the problem with the wiring loom. Would have cost about 500 pounds to fix, and they still had to modify the ends on it - was lucky I didnt have to pay for it myself!

    Cheers for the comments lads.  I'm waiting for the weather to warm up a bit more and the old man and me are going to see if we can sort the loom.

    If not, I'm going into Abarth and handing them the keys I reckon.  2 major issues in 2 months that should never happen to a car (this and clutch pedal snapping) and I'm losing my will to keep it  >:(

    So, this problem is sorted.  Whoever pointed me in the direction of the joint where the loom comes through to the boot, I doff my cap to you sir. Picture attached showing the issue... Glad my old man is a mechanic as I'd not like to price this being fixed by FIAT / Abarth.

    Glad you got it fixed OK, members sharing their knowledge of problem solving just one of the benefits of an enthusiast's forum like this.

    I'm hoping that the early converters to the 595 will have resolved the issue of wind noise before I take delivery of mine in March so that if I have the same problem I can pass the info on to my dealer.

    It had to be the wires. Glad I could point you in the right direction.
