    Hello everyone. I have a ‘13 spider with a turn signal issue. The blinkers will not work at all. The buttons on the steering wheel click as normal but the front and rear blinkers do not activate or show on the dash. The hazard lights do work and I hear the relay click lower left steering column.

    I assume there is a relay issue. I also noticed the TPMS Sensor will not calibrate any longer. I think maybe the relay or fuse issue may be related.

    Anyone know the location, relay/fuse type and number for replacement? Seems silly to go to the dealer for a simple fuse/relay replacement.

    Thank You in advance.

    I see the owner's manual doesn't provide any clues. There is no fuse listed specifically for the turn indications, just the hazards (and your hazards are working). Perhaps there is a fuse which powers the steering wheel functions or instrument functions. Is there anything else on the steering wheel which is not working?

    If you don't have an owner's manual, just scroll through the pages on this website (using the arrow keys) for the location and identification of other fuses:

    https://www.manualslib.com/manual/900232/Ferrari-458-Italia.html?page=189#manual

    If you can find the relay (or module) which clicks during hazard operation, perhaps you could write down any part numbers on the module. I couldn't find an part numbers on the Ricambi website.

    The TPS does have its own fuse, but it may not be a fuse issue.

    Thank You for the details. I will check the steering wheel related fuses. I would assume blinker, headlights etc would all be tied together or be in a similar location. If I find it, I am writing a supplement for the damn manual :)

    What was the resolution? The turn signal buttons on the steering wheel aren't working, but the hazards activate the blinkers fine.

    Not sure if this helps or not:

    Most vehicles have a turn signal flasher and a hazard flasher. The flasher may be bad. They are usually the same and can be swapped to test.

    Normally if the turn signals do not work it is the NVO board within the steering wheel itself. There is no fuse for the "blinkers". I had this happen on my '13 Spider and it is not uncommon for the board to go bad. The part is about $900 and can be swapped out by your self. Be careful though - If you have LED's on the steering wheel , then you will need to get the board that has the LED's activated. If you get the wrong board, the dealer will need to get the proxy file from Ferrari to activate them.

    Most vehicles or most Ferraris? :p

    The Ferrari 348 was probably the last to have multiple relays for turn and hazard (3 in fact), but these were not always interchangeable. After the 348, they switched to a single (7-pin) module for turn and hazard (355, 456M, 550, 360.... ) but now they seem to have overcomplicated things with the 458.

    Must be something with 2013 model year. A friend had an issue with turn signals on his 2013 458 B and similar description for repair. I think total cost out the door with tax was around $2k

    Correct, when the hazards quit working on my F355 spider, and I saw the cost for a replacement relay, I figured I had nothing to lose to open it up and check. I lucked out and found a very obvious bad cold solder on the small circuit board inside. I quick touch up with a soldering pencil and it was back working again.

    I don't know if it is an issue with that specific year or not. I bet we'll see more of these failures in the other years as well. Matter of fact, I wouldn't be surprised if it showed up in the F12 as well since they share the same steering wheel. I paid $1500 for the replacement (part/labor/tax) from the local dealer. $2000 seems high but it probably depends on the shop doing the work.

    Thank you! I also have a feeling it's the NVO board because hazards activate the blinkers and dash lights correctly, but the turn signal buttons aren't doing either. I appreciate the heads up on the steering wheel LED's (now just need to research Part # 255426 or 308322).

    Any tips/tutorials/video on removal for a 458? (This is a 2010) It appears removing the faceplate is just a matter of it popping off after airbag removal. How do I remove the airbag though -- same process as this F430 video?

    The airbag is removed via two screws that are located on the side of the steering column shroud, just behind each paddle. You need a tamper proof torques head bit to remove the screws. Once both screws are taken out, the airbag simply slides right out. The NVO board is the one located at 6:00 in the opening. It will have a number of wires plugging into it. Disconnect your battery before removing!

    I am not a Ferrari factory certified tech:

    If removing an airbag, the procedure is to remove BOTH battery cables then touch them together to discharge any residual current before removing the airbag.

    I looked up part #'s out of curiosity (I don't have this problem with my car...yet, lol). I just see 2 different boards, depending on assembly #. How do you know if the board has "LED's activated"? I didn't see any reference to that. Also, If the wrong board is installed (without the LED activation), is that something that an X431 Pro tool can take care of, or is it a must visit to the dealer?

    Chris - Unfortunately, I'm not sure how you tell which part number has the LED activated. From my experience, you must go to the dealer to have the LED's activated. Since it requires a proxy file from Ferrari, that is the only way I know.

    Ok thanks, I guess I'll do more research if a friends, or my car has that problem.

    Good question. Because I just called a Ferrari dealer and explained this concern and they said one board is for earlier models, and others for later models. So I just ordered the one for the specific VIN number, even though I am not 100% certain the LEDs came factory with this car.

    But post here how your experience turns out.

    That's all I saw also. I only saw 2 boards. One for earlier cars, the other for later (approx. 2014 & 2015's).
    I don't have an issue with my car (yet, lol), I just like to learn about it.
