430 Only two gears

I don't really know what all the codes are. They don't seem to match up with the list I have. However...

This might be a CAN Bus error. Seems like a common problem... and not always easy to resolve.

Here is a basic wiring diagram of the "C" Can Bus:

If no vehicle speed, then perhaps the Brake System ECU is not talking to the instrument panel and the F1 TCU. I don't think the F1 TCU will give a gear higher than 2nd without a vehicle speed signal (sent on the CAN Bus).

The wiring diagrams we have are not really complete, but let me know if you need a particular system diagram and I'll let you know if I have a usable diagram.

Seems like some mice have been chewing on your cables )

 

P0600 means the ECU is not communicating with a certain module, like the tcu etc.
I'm guessing some connections went bad while the cats was sitting, developing corrosion.
Start checking every connector

 

Hello all,

can someone assist please. I almost have the same issue. My car was parked for 2 years and when I switched it on, after replacing to a new battery I have got the following codes attached in the picture.

U0141, P1600, U0142, P1601, P0600, U1601, U1602, U1603, U1605, 02B, 0004, 0E3A, U1700, P0600

Looks like normal low voltage codes. Clear them and drive.

 

I tried that but it keeps coming up

 

A lot of those codes seem to suggest there is something wrong with your manettino. If your new battery voltage is confirmed ok, I would suggest checking the CAN Bus wiring on the steering wheel. Unfortunately, this kind of stuff is probably best left to the experts. You would have to remove the airbag to get to the wiring.

The CAN Bus wiring goes through the steering wheel clockspring. It's possible you have a clockspring issue. Seems strange though that it would fail with the car not being used. Anyway, this (somewhat simplified) diagram may give you some idea of how to check the CAN Bus wiring:

EM37 is the steering wheel side of the clockspring (8 pin plug). I've represented this with a red box with pin numbers marked on it. D072 is the steering column side of the clockspring. XA54 is the OBD2 port and E003 (A, B, C, D) are the instrument panel connectors.

EM37 is a half black/half red plug inside the steering wheel (see photo). Pins 1 & 2 are the CAN Bus wires. Maybe look for continuity between pins 1 & 2 on connector EM37 and OBD2 port pins 9 & 1 (respectively).

I hope Mr Stewart doesn't mind me borrowing his photo

On EM37, pin 1 should have a pink wire on it. Pin 2 should have a grey wire.

Of course, the manettino module itself may have failed. At this point in time, there might be lots of possibilities. I wouldn't recommend making any expensive purchases without consulting a (real) Ferrari technician with more experience on these cars.

 

Well noted dear.
Small thing I would like to ad that when I remove the battery cable and re connect several times it works normally and when I go for a drive all the faults happens again.

 

Ah.. so an intermittent issue. That's going to be even harder to faultfind. If it's a clockspring issue, maybe you could reset the faults, then move your steering wheel before driving too far.

Unfortunately, with intermittent faults which cannot be easily diagnosed, sometimes the only action is to start replacing expensive parts.

 

I’m doubting it’s from the instrument cluster.
It’s either wiring issues or the entire cluster failure.
Can you assist please with the instrument cluster wiring diagram ?

 

You're doubting what is from the instrument cluster?

Are you looking for an instrument cluster internal diagram? An instrument panel pinout? A CAN Bus diagram?

 

Hello qavion,

I mean the fault codes happening to be in my car. It might be from the instrument cluster. As it’s not responding and when I disconnect and re connect the battery several times it works normally and then it goes off. So maybe the wires between the instrument cluster to the ECU is faulty.

 

For information, most of the communication between the Instrument Panel and the Engine ECUs will be through CAN Bus "C".

I only have a CAN Bus diagram for the Scud

Instrument panel Plug B pins 4 & 5 feed into the CAN Bus C network.

Note that the steering wheel is on CAN Bus "B" (as shown in post #10). Most of your messages seem steering wheel related, so I don't know if there is any point checking CAN Bus "C" connections.

 

Hi dear I have fixed the major issue. By repairing the instrument cluster three components was Changed I have uploaded the photo and I uploaded the photo of the other active codes related to the differential and immobilizer I am not sure what to do now.

Interesting. Now most of the faults seem to be related to the brake system. "NFR" refers the brake ECU.

The steering wheel is reporting a brake fault.
The Suspension ECU is reporting a brake fault.
The instrument panel is reporting a brake and suspension fault

And you have some immobiliser issues.

I don't know if there is a Brake ECU fault or a wiring fault. There are some fuses for the brake system under the dashboard on the right hand side (I think) of the car. Also check the maxi fuses near the battery (#6 and #8)

The fuses are near the Hazard/Turn light module.
