So my first gremlin has reared it's head. I used the car as normal this morning, parked in the garage, went back out an hour later and got an indicator warning. Initially for one headlight but it's actually one entire side of the car is not responding. So front and side and rear not indicating on one side only. I'm assuming this potentially a fuse/relay issue but I have no idea where to start. I've looked on the WSM and the owners manual and can't find anything obvious. So far after three restarts still not working. If it makes any difference at all car has had a lot of use in wet weather recently. Ideas please good people?
I've so far never had to do that although I do understand that is quite a normal "thing" on most modern Ferraris. Is there a specific procedure and does anything need to re learn when it's reconnected?
Fast forward to 3:20 on this video:- Is a battery disconnect nothing more than switching this isolator off?
OK, battery disconnected, left for 10 minutes, reconnected. No change. Still no indicators on one side of the car. So I'm open to suggestions. Having gone through the list of fuses and relays there doesn't seem to be anything specific to turn signals, so I'm not quite sure what to check next.
So this morning I thought I'd just check anything obvious, fuses etc just to make sure everything looked as it should. Anything to do with lights, relays fuses etc seem to be in the passenger footwell location. So that's a good place to start. Here's my footwell (remember this is a RHD car if the orientation looks slightly odd):- Image Unavailable, Please Login Here's a picture from the manual of what it should look like - So far so good. Image Unavailable, Please Login Here's the key to what fuse/relay does what......on the next page of the manual This is where I'm struggling. Obviously in the car the panels are in the other orientation......however the smaller board on the left hand side in my car doesn't relate to the diagram on the right. T-38 was the one I wanted to check. This is not helpful! Image Unavailable, Please Login In any normal car the symptoms I'm getting would point to something like a failed relay, the relay would control both left and right indicators with different circuits inside the relay for each side. I just cant figure out what controls the indicators in an FF, there doesn't seem to be a relay. So I'm assuming if there's no relay it must be an ECU. Does anyone know how the indicators are controlled in these cars?
That was the next one to check, however that's another one that simply doesn't exist on my board, at least the board in my car doesn't have the same positions as the schematic diagram in the manual.
Try activating the other working turn Signals to see if u can find its relay by ear. Most likely the her side is nearby. Plus the wording in the manual may be fully reflective. Then contact the dealer to find out the correct module for you. SV
Good idea, I'll try that in the morning. If it's a case of replacing a relay or fuse I'm happy to have a go and see if that solves the problem, in the interest of expediency. Failing that It'll go into the dealer, it has warranty.
Progress, of sorts thanks to Keiths (obvious and logical) suggestion above I've tracked the "ticking" of the indicators to the fuse box where the parking brake is locate by the steering wheel. Page 235 of the manual gives a breakdown and a list of what relay/fuse does what and where it is. Except there's no diagram to tell you where it is. It's completely missing for this fuse board from the manual. I had assumed (rather logically as other manufacturers do this) that there will be a diagram on the lid of fuse box once you remove it. Of course there isn't, this is a Ferrari. So we have a list, a photograph but no crib sheet to tell what's what. Image Unavailable, Please Login So the reality is we're down to turning on the indicators and touching the relays to figure out which one is "ticking" and that's probably what I want to be changing to see if it solves the issue. I've narrowed it down to one of these three pictured below. The "ticking" is difficult to narrow down specifically as it vibrates the metal plate these are all connected to, but I think it's one of the red ones. Can I get them out? Not a chance, I'm applying so much pulling force I'm worried I'm going to break something and maybe these Red items (whatever they are as we have no crib sheet) are not actually designed to be removable.

Hold on a moment. I have a PDF of the WSM I downloaded off a link on here only a few days ago. I found this on it. Image Unavailable, Please Login T01 20 Micro relay, low beam lights T11 30 Micro relay, heated rear screen T12 30 Micro relay, Services 1 (dependent on INT/A ignition switch) T13 [joint] Bridge [30 - 87] (services 2 power supply) I'm none the wiser still, but it feels like a small victory that I actually found the diagram that tells me what's what.
Update. Two hours in the dealer this morning having diagnostics run. By applying power to each light unit they were all tested as operational. Plugging into the "computer" didn't reveal any results so the tech then went old school with a voltmeter and methodically went through the wiring. No power to the rear indicator which was eventually traced back to the Body Control Module (sited by the fuse board under the steering wheel). So one of them is being ordered and will be replaced as soon as it's arrived. It as explained this is the "brain" that talks to all the other units in the car - unhelpfully if that goes wrong you could get any sort of symptom in the electrics anywhere in the car. I have been having oddities with the central locking system so we're wondering if that was an early sign of a problem with this unit - I guess that will be revealed when it's replaced. Should be a week or two then I'll post another update on the off chance in the future someone else gets a similar issue.
SOLVED. My FF has arrived back from the dealer this morning with a full complement of indicators. The issue was the Body Computer Node - Part 001 on the parts diagram here:- https://www.eurospares.co.uk/Ferrari/FF/FF_(RHD)/PartDiagrams/0134/VEHICLE_ECUs It's an ECU that sits behind the fuseboard/ecu under the steering wheel. Replaced with a new one. It effectively controls all the other ECU's in the car, so unhelpfully you could have any random electrical error be traceable back to this - but it's useful if someone suffers a similar failure. In my case, no power was being supplied to the rear near side indicator and it took all three indicators out on the left had side. Interestingly my central locking appears to be much more responsive. I was often stood by the car pressing buttons multiple times and opening closing doors before the boot (trunk) would activate. The tech did say this could very easily be connected considering what the body control node does.....time will tell. This was covered by the Power15 warranty. They also did the recall whilst it was in which saves another trip back. This is Ferrari Sevenoaks in Kent - They've been polite, accommodating and helpful so far.
@21ATS Hey Alan, thanks for posting all of this. I just had an issue that's a bit different, but equally annoying, lol. My FF is giving me a headlamp failure and a turn signal failure on the front left, however the headlights and signals are all actually working perfectly. Low beams, high beams, every single LED in the running lights function as they should. I get the fast clicking turn signal to the left on the dashboard, but on the outside all turn signals are working just fine and at the proper flashing speed. So ultimately there is some odd electrical signal that is tricking the error message into thinking the left headlight has an issue. I tried as you did a battery reset and I also have a Foxwell scanner with Ferrari software to clear the error codes, however the error comes right back on after clearing. I do not have AFS, so no Adaptive headlight ecu or module to worry about. I hope it's not an electrical gremlin inside the headlight itself since that would mean replacing the whole light, so I'm trying to test every other possible scenario and your notes are very helpful. One question, any chance you asked if when they installed the new Body ECU if it needed to be reprogrammed for the car, or if it was just plug and play? Thinking if that may be something I can just replace on my own. Cheers!
This wasn't a DIY thing, it was done buy the dealer under warranty, so in all honesty I can't answer your question. What I do know is they had a particular process (an order of tests) that ruled out certain problems and eventually narrowed down the issue to the ECU responsible. So for something seemingly as random as this, it might be worth a trip to the dealer to determine the root cause. Sorry I can't be any more specific. The unit that was replaced in my car really does control almost everything inside the car so helpfully could cause any number of random problems. SPecifically mine was no power making it to the rear indicator, yet the error was being shown as front indicator. Maybe get a meter on each cable and see if something is not getting power? That seems to be the key to the problem. Hope that helps.
Thank you for the response. So problem was in the rear but the error message for the front, ahh that Ferrari experience! lol. Problem for me is everything is getting power and working correctly, but still has an error message. I think what I'll do is swap all the bulbs from one side to the other and hopefully that causes the error message to change to a different side and that will tell me what's wrong. Then try testing the relays/fuses in the body ecu. If all stays the same then looks like I'll have no choice but to take it to the dealer. Thanks again!
Yeah, don't assume the error message is completely accurate. You have an issue somewhere in the electrical system specific to the lighting/indicators. So limit your serach to that to start with.
