F430 F1 Gearbox Not shifting past 2nd, CAN BUS wiring diagrams.

XA, YA, XR, etc, are inline connectors. The diagram is for a Scud, but should be close enough.

I believe CAN Bus problems can be caused by faulty devices (ECUs, etc) or inter-ECU wiring issues. Not sure how you'd go about figuring what is causing your issues. Maybe best to seek professional help (guys with specialist equipment)

Did you bend any pins reinstalling plugs during the delete/bypass?

 

If the F1 system including the ediff is of suspect..I would spend my energy looking at F1 pressures and timings ..

If you want to chat send me a PM

I think it may be quicker than trying to figure out some of the ghost CAN messages

Odds are it is a bad F1 solenoid, like Dominick said. Proper analysis with an SD3 or equivalent will tell you the answer. Mine had the same symptoms of not shifting past 2nd and it was a solenoid.

 

following to see troubleshooting steps and final diagnosis

 

OP

Did you resolve your issue ?

My offer to help still stands

WOW.. great find. PSF5 powers the e-Diff and Suspension ECU, but perhaps more seriously, also sends power to the alternator regulator, too. Would this cause voltage regulation issues? (overvoltage/undervoltage).

If it happens again, I would be checking the alternator wiring.

 

You can usually find pdf Workshop Manuals online at relatively cheap prices (although a lot of sub-chapters are missing). Wiring diagrams are a different matter. They are hard to find, very expensive, incomplete, full of errors and are sometimes hard to follow. I've tried to convert some of them into more user-friendly diagrams, but the larger ones can be quite intimidating at first glance. Here's my E-diff diagram (a work in progress like the rest of my diagrams):

You actually touch on a very good point. I've been trying to find shop manual for the F430, but have been unsuccessful, do you have any leads?

 

A Google search reveals

https://www.emanualonline.com/cars/ferrari/f430/ferrari-f430-spider-service-repair-manual-emo-17422.html?

It's slightly more expensive than I remember, though.

If you have a coupe, this should be fine for most of the car.

 

Hi i have a F430 and have tried and checked everything that i have imagine reading in several posts, i have cluster with no gear N light, cst, e diff, suspension, tpms,abs, i have right now borrowed a SD3 but i am no expert just can get codes etc it have codes in cluster b1005 suspension failure already test solenoids and good also wheel sensors, b100c brake failure, u1602 no can from f1 gearbox, u1604 no can from tpms ecu.
I am overseas with no ferrari etc here so i can pay in case for guidance to solve the problem my email is [email protected] please some help!!!! Many blessings

 

Make sure battery is fully charged and tested to be good ...then wipe out codes and see if they return ..if they do post here

 

Hi i just checked battery since it is new it reads 12.76 and car on with lights and ac 14.2 i erased codes and they say present and cannot erase, wich are on cluster b1005 suspension failure, b100c brake failure,u1602 no can message recieved from f1 gearbox, u1604 no can message recieved from tpms ecu, on suspension U1706 no communication with NFR, on ediff C2006 Pressure sensor, C2007 Pump relay connection both present, abs C1103 configuration eol change

 

see if you get wheel speed on each wheel on diag tool

 

Yes i did the wheel speed and all sensors where ok, i also did suspension solenoid test and all where good, i was looking on the SD3, do you know what is the pressure sensor because i feel the clutch when it goes out of 1st it does like you would take clutch put and if you dont acelerate quickly it shuts off like i would not shift good on a manual

Where are you located ? Time zone ?

 

ImCar was good no lights in dash gear diaplay ok everything working but had a right fuel pump bad with a 15 fuse bad and we replaced that, we also replaced the 2 rubbers on the rear axle, and replace aluminum block plate of f1, after that started the car and all the light lighted up and no gear display

 

I am in central america 6:39 pm in el salvador

 

what is a aluminum block plate

 

Rare thing before clutch had 16% used at 20.98 mm new closed clutch position and now it has new closed clutch position 22.29 mm -2%
