Anyone seen this.. Got in the F12 for a quick spin, turn signal indicators are not working. Hazards work fine, all other lights, etc. Ok. Would try and check the fuse, but the owners manual does not have the Indicators fuse listed (which has been the the case since the 1963 250GTE that I had, and the 355/360). Anyone know what the fuse number and location on the F12 might be, so I can check it? Thanks for any assist...
The text below was posted in 2013 answering what I think was a similar question to yours, "I started tracing wires and started with the hazard light switch since I did have the center console out. I started looking at all the plugs in the console to see if I connected one wrong and I noticed that my mirrors would not adjust so I looked at the wiring diagram and found a wire common to both switches. I then decided to look for the mirror fuse and hoped it would be the one. Lo and behold it was blown! The labeling is "+15 Radio-Clock-Wing mirrors-Light switch" in the wiring diagram. This clued me in as to why my radio wouldn't turn off with the ignition (stayed on for I think and hour then internally times out) and the clock always had the wrong time between driving the car. The fuse is labelled differently on the RH Fuse box cover behind the passengers seat " +15 Radio-MR.Stalk-Clock" "Stalk" kind of clued me in because sometimes in other vehicles the light switch is called a "stalk". The fuse number is technically 43 and it is on the fuse box nearest the tunnel on the upper LH corner of the fuse box pg 4.22 in the owners manual. Ferrari of Houston didn't even know there was a fuse and only one tech in Scottsdale had a clue but could not remember the fuse number or even if FOR SURE there was a fuse! Anyway for anyone reading this we are probably the only guys in then universe to know exactly what fuse and what other symptoms to look for! " Virgil
I forgot to mention that the question to Virgil's reply was : Where/what number is fuse for turn signals?
Sorry just checked again and that question concerned an older Ferrari not the F12. So is false alarm.
Yeah I read that, that was for a 458 I believe.. Not the same fuses, as no stalk is mentioned in the F12 fuse listings (I checked).
For those that might run into this on the 458, California, 488 and F12 (Same part for all models) - evidently this is a somewhat common problem (from dealer) there is a electronic control board in the steering wheel, which contains the turn signal activation bus. There is no common fuse for the turn signals. This has been known to go out, or intermittent problems with the turn signals. Replacing this board is the solution. Good news the newer build numbers are cheaper than the older ones As chance would have it my problem seems intermittent, mine is working again, but will have it replaced during the spring service, once winter is over.. Part number if anyone ever needs it, as this part is typically shipped from the factory - ie. Will need to order ahead of time.. 255426 ELECTRONIC BOARD Applicable up to Ass. No. 119500 $475.42 308322 ELECTRONIC BOARD Applicable from Ass. No. 119501 $411.25
For the breakdown diagram - the control board is Part number 30 in the diagram below: Image Unavailable, Please Login
This happened on my 458. Its called the "NVO" board. I had the same symptoms- sometimes worked, sometimes didn't, and then it stopped working. You will definitely want to have it replaced. The good news is its fairly easy to have them replace it.
