If you help me find an F355 wiring diagram, I offer to:

Here's the tail light issue thread I mentioned

https://www.ferrarichat.com/forum/posts/148657739/

Quite comprehensive (diagnostically). Unfortunately, no follow up (to see if was finally resolved)

 

Actually, quite a few mistakes were made during diagnosis (which were eventually corrected). You will either have to read through the whole thread to understand orit may be best simply to start a new thread.

Note also that the car was a LHD car. What is yours? With UK cars, I can't assume... as you have lots of both running around.

 

Definitely check the hydraulic fluid level for the top. The 355 and 360 series are notorious for losing fluid over time and require top ups every two to three years. The previous owner of mine never had it checked and damaged both rams from letting them run dry. It was many thousands to replace them both. I just made a point to check every three years and top it up to the max line. In three years it will be just at the min line typically. Go another three years or so, and you can run the pump dry.

 

I guess I missed the obvious connection... How far do the windows move before they trip out? If the windows don't move down a couple of centimetres when you unlatch the roof, the Roof ECU won't allow the roof to move.

 

I finally got to drive it and have a 20 minute look. The roof lowers the windows, moves the seats, you hear the pump run...nothing happens then a beep. This must be a hydraulic issue then.

The central locking does work so that means it's not that fuse. I had read somewhere about a relay (1 of 3) with the same effects as this. Now my little baby is asleep I am going to take a close look at your diagram.

From a 5 minute drive, the only other things I have found is a park light that doesn't extinguish (calipers not releasing very smoothly I think) and a plethora of horrible plastics!

Thank you for your help. I am still thrilled to have wiring diagrams - had an S1 Exige a few years back and no correct diagram and it was hell when it died!

 

This seems likely! Hoping the rams are OK...that sounds like expensive parts!

 

It seems they are OK with the engine running. Some silicone lubricant is in their future!

 

Oh and the hifi unit says "code"...Uch!

 

Seems likely. Check your fluid levels. If in doubt, use the backup electrical switch. That bypasses almost all the electronic logic. Only the relays (and the park brake switch) are active. Make sure that your roof is folding properly (the first roof "rib") should go upwards, not downwards.

I forgot that the parking lights are split into two different circuits (driven by different frunk fuses). i.e. LH lights and RH lights. It seems strange that both tail lights are not working. Can you get your rear lights to operate using the P pushbutton on the centre console?

 

Yes - indeed the P button lights the tail lights up. I will have a look at the thread.

This is what I found before - sounded like my issue.

 

I also forgot that other thread was one rear tail light only. It's unlikely you have two wiring issues. Also, I edited my previous message to remove the reference to bulbs/bulbholders.... There are 4 bulbs... so likely not all 4 are out.

 

Relay e9 in luggage compartment might be worth a look from a quick look at the diagram. I might need to stare at that a bit longer yet!

 

Are your dash lights not working?

This is getting confusing. The normal front/tail marker lights use relay F (the Park Button bypasses the relay).

Relay F (or E9) has dual contacts. One contact feeds both L & R (front and rear) marker lights. The other contact feeds the Instrument lights and rear numberplate lights. I don't see how it can be a relay issue if only the rear lights are affected.

No dash lights. I said "interior lights" on my first post, but I meant dash lights!

 

Ooops.. back to the drawing board.

 

Just to confirm... Your front parking lights (left and right) are definitely working with the column switch?

(Sorry.. multiple edits)

 

If you want to swap relays for faultfinding, the only other dual contact relay is the secondary air relay (E10) in the footwell.

 

Dip/main beam headlight is about all that's working I think, but will check when I can.

Thanks on the relays - a very useful nugget of info. This has to be the first port of call.

 

That is, assuming UK cars actually have a secondary air system. Anyway, sounds like you're heading in the right direction (especially if the front marker lights aren't working).

Because your low beam and high beam headlights are working, at least you know your column light switch is getting ignition power.

I just noticed I mislabelled the signal going to the coil of E9 as earth. It should read "power" (see below)

Relay F changed, lights working!

Had a compatable one in a tool cabinet!

 

Excellent.. Thanks for the update.

You probably would have found it faster without my help (Sometimes it's hard to "remote diagnose").

The old relay is probably ok.. It probably just needed to be slapped a few times to wake it up from "hibernation".

 

Well the diagram helped a lot! Thank you!

Next up the bonnet bulb not illuminating, noticed that while I was in there. Haha

 

I don't know if you're aware, but the bonnet bulb only works with the sidelights on.

Power comes from fuse 12. See the Lighting Diagram. In the middle of the diagram is "06040"

Another possible problem is people removing the frunk "carpet" and forgetting to hook up the interior light plug (found in the relay panel cavity)
