430 Scuderia ABS pump in F430

Guys,

Need tech support here.

Can the ABS pump in a 430 Scuderia fit a F430? Time for a replacement and since car is already running full 430 Scuderia brakes(calipers and ceramic discs and brake booster) I am torn between ordering the two:

430 Scuderia ABS pump part number 226683
F430 ABS punp part number 221252

Car has been running F430 ABS pump supporting the 430 Scud brake system for past couple of years with no issues till it decided to nuke itself 3 weeks ago. Just wondering if I should order the scud pump or just the regular F430 pump from Eurospares.

Anyone can help me on this? Thanks in advance.

 

No. You will need the other modules and to rewire the car accordingly. It does mean you can convert to Superfast 2 though.

 

Btw I have a good F430 ABS module if you need it.

 

You sure about that? I seem to recall that there were gearbox differences between regular 430 and Scud (to handle the faster shifting?) - maybe I recall incorrectly...?

 

Yes: Superfast 2 comprises the gearbox, TCU, actuator, and valve body/solenoids.

 

Thanks mate. Funny thing is, I am already running the superfast 2 gearbox with tcu and relevant wiring on my car. I checked the parts invoice and did not see that they swapped out the abs pump so that means I was still running the factory F430 abs pump. Don't ask me how that worked for as long as it did. So I guess now there is no harm getting the 430 Scuderia abs pump then?

 

According to my experience that is impossible. The Scuderia TCU needs the Scuderia ABS module to work: I have been through this with my conversion. The Superfast 2 TCU uses data from the ABS yaw sensor to improve gear shifts, and on the Scuderia the sensor changed from two channel analogue to digital (CAN bus). The ABS and car main body harnesses were changed to suit. In turn the ABS module requires the Scuderia instrument cluster which is also specific to the Bosch 8 ABS module, and ditto the E-Diff module, which also uses the digital yaw sensor as an input. The above systems must be installed as a package otherwise nothing will work.

The torque cut mapping in the engine ECUs is also different for the 60ms shifts and installing those requires the Scuderia MAF sensors, wiring, and some other sensors.

If you need any help identifying modules let me know as I have been through this recently.

 

2009 F430-F1 Having a major problem ECU not communicating with ABS, have changed the ECU & the ABS Computers, this has not resolved the issue. The manettino switch will not go into Sport Mode BUT remains in Low Grip Mode. I think this is the Default Mode. Since I only use the car on the race track I am NOT able to use "RACE MODE". See picture attached, the error symbol is showing up in the display on the tach. Any help will be greatly appreciated. Have taken the car to three Ferrari Dealers, NO LUCK

Bit of a noodle scratcher this one. When you say “ecu”, are you taking about the dash/body ecu in the gauge cluster, or one/both of the engine ecu’s?

What are the fault codes- please post a complete list? Anything with a “U” prefix (which would point to a general CAN network error)?

the person working on the vehicle just said: there are no engine codes, its just the suspension ECU

 

Be very helpful if we knew what codes the suspension ecu was throwing.

Can you buy a wee Autel AP200 scan tool (~$70) and give us a download of the fault codes on all of the modules?

Yes I will and get to you with the codes

 

Sorry for the delay. U1706: No communication with NFR
Mechanic pulled the steering wheel and examined Manettino switch, put back the steering wheel and started the car, car started not showing the wires symbol in the display and was in Sport Mode, plugged in the computer and was still showing an error code. Turned off the car and restarted and the symbol came back putting the car into default mode “Low Grip”
Other error codes:
U0029: Vehicle communication Bus A Performance, Malfunction (Plaus).
P1059: Vehicle speed signal (Can)
P0464: Fuel level sensor “A” circuit intermittent
P1602: Permanent power supply

 

Do you know if these are all active faults or missed faults (I.e stored codes)?

The P1602 comes up on all Ferrari’s of this vintage whenever the battery is disconnected; it’s not something to worry about as long as it disappears when it’s cleared.

The U codes are the interesting ones. No communication with NFR means that the ABS computer has stopped talking over the CAN bus. Since the ABS module is integral to the driving modes, it explains why the default (safe) low grip mode is selected.

P1059 speed sensor code is also consistent with with above, since the engine ecus get the vehicle speed reading directly from the ABS module.

U0029 has me more perplexed, as it’s indicating poor performance on the A Bus. There are multiple can BUS’s on these cars- usually you have

- A high speed 500kbps bus for the critical functions like engine, abs, suspension, gearbox and steering that all need to exchange information at a high rate,
- A comfort CAN bus for things like electric seats, radio, climate control etc, and
- A “fault tolerant” CAN bus that’s used for the safety systems- airbags etc. It’s fault tolerant because it’s designed such that one of the twisted pair of wires can be broken, and the system can still limp on with one wire.

What’s odd is that Ferrari normally call the high speed CAN the “C-CAN”, whereas the fault is indicating an issue with the A CAN. Let me check the wiring diagrams though and see if this is the case with this car. Maybe A CAN is the high speed CAN bus which all of these faults seem to relate to. Well almost all- I’m not sure what the deal is with the fuel level sensor fault. Again, I can look up in Modus and see what the factory help says that fault indicates.

One working theory then is that you’ve got some interference on the high speed CAN. Might be useful if you could do some CAN bus sniffing to see what’s being sent over the CAN. Ideally you would have a working 430 to compare message with. You can do this yourself with an eBay CAN tool.

Let me get back to you on the items above.

Thanks for the quick response, see picture attached.

Is traction control and ABS off as well? If so this might be the exact same problem I had. Marintino, abs, traction, stability, suspension lights were on and it was stuck in weather mode. After about a week in the shop they replaced the diff sensor and didn’t fix it. Then after a bunch of digging they found it to be the yaw sensor. They get all their parts from Ricambi and Ricambi said this was the first yaw sensor they ever sold. Car has worked flawlessly since. Hope this helps you.

Struggling to find any specific guidance on the network fault code above, but I can confirm that the high speed CAN bus is called C-CAN on 430 too.

See below components on this network:

You have:
- steering angle sensor
- abs ecu
- instrument cluster
- suspension ecu
- tire pressure ecu
- gearbox ecu
- e-diff mode
- both engine ecus.

I can see then that a fault with the yaw sensor could be related. Might be worth a shot?

I will share the information with the Ferrari mechanic, really appreciated the help I am receiving

 

Have you checked the multi plug on the ABS unit? Unplug it to inspect.

 

Yes we did and the plug and connectors were all good, placed star washers on both ground terminal, have disconnected the Ferrari battery tender. This morning, turned on the ignition key, car turned on in "SPORT" , Turned the Manettino to Race and the LCD displayed Race, turned the switch back to Sport and the display said Sport, did this several times and the switch worked as it should showing the selected mode, check the computer : no comm with NFR. Makes no sense.
Turned off the ignition switch, waited 5 minutes, turned ignition on and LCD display and Manettino switch went back to DEFAULT "Low Grip", checked the error: no comm with NFR.
Turned the ignition on again, DISPLAY shows "SPORT", Check the error message: NO comm with NFR.

 

Very odd.

Each time, was the mannetino in the same position when you switched the ignition on?

The switch was in Sport mode

 

Every time? You didn't change the position it was in between the different ignition on attempts?

There has to be some reason its changing with the different start attempts.

 

It makes no sense. This morning installed a new yaw sensor, started the car Manettino switch was in "Sport", CHECK OK appeared in the LCD and the car was in sport mode. Drove the car and the car drove fine. While driving changed the Manettino to "Race" that worked, changed back to Sport, that worked, changed to Low Grip, that worked, changed back to Sport, that worked. Came back to the shop and checked for Error Codes. U1706, No comm with NFR
Removed the yaw sensor and replaced with original, started the car in Sport Mode, CHECK OK appeared in the LCD and the car was in Sport mode, checked for errors. U1706 displayed.
Drove the car again with the original YAW SENSOR installed, changed settings while driving from Sport to Race and then back to Sport and then to Low Grip, all SETTINGS WORKED WELL and the car drove just like it does on the Race Track, fast and smooth. Came back to the shop and checked for error codes U1706 displayed
