    @Wolfgang72 would you have the CAN signal needed to keep the dash in a "happy" state?

    Not sure which kind of parameters are you looking for. Can you please specify?

    For sure. First of all, the CAN bus is directly wired to the engine ECU. There are no other ECUs connected (the gear display in the dash uses a dedicated line).

    The TCU puts everything in a single CAN message. It's a combined control/status message. The status part contains gear, shift status and so on. The control part contains torque reduction request, target RPM etc. There also is a bit that asks to shut down the engine and other features.

    As said before, communication between engine ECU and TCU is bi-directional. That is, the engine ECU sends out CAN messages, too. And it actively checks if these messages got acknowledged by a receiver.


    I don't know DTC P0600 in detail, but my guess is that it reports an interrupted CAN connection. That's probably due to both, the missing CAN message from the TCU and the missing acknowledge of its own CAN message.


    I would be happy to help you building a prototype. You would need a CAN node that connects to the engine ECU. If configured properly, it would automatically acknowledge the CAN message. You would then set it up to send out a "neutral" CAN message that imitates the TCU. Not that difficult.

    I think it would be quire do-able too.

    This is what you would want I think:
    https://www.cananalyser.co.uk/candoauto.html

    I've spoken (ages ago) with their MD, who indicated that they would be happy to send out the units pre-programmed for you with basic message protocols if you told them what it needs to do. You then just need to tap it onto the CAN line somewhere and suply it with 12V/ground.

    From their website:
    "The configuration software also allows the module to be configured to transmit a number of fixed, periodic CAN messages automatically on power up."

    Mainly looking for the clutch travel, clutch travel reference, PIS, selection and engagement min max values. The entire list of the parameters from the TCU would be absolutely lovely. Thanks.

    Honestly, the easiest solution to this problem is to send your ecu to specialized ecu repair in Florida. For like 500.00, they can flash it to a manual. If you ever convert back just do the same to re flash to F1. Works flawless.

    I think the price at ECU Docs has gone up quite a bit...would still love to take care of the P0600 CEL without flashing the ECU, although unlike in other areas of cars, I am worthless and must leave it in the hands of guys like @brogenville, @tgaspl17, and @Wolfgang72. If it's easy to make the doohickey, it'd be a great item to sell and I would gladly pay for one (probably two, actually)

    Hi, i'm the owner of a F355 F1. Unfortunately i've a problem with the gear of the car. I've checked all in the car, but my suspect is that the flash data inside ECU are not correct. I've read the ECU flash and i see that checksum is D3BD, but I dont kwow if data inside are correct, becouse car swicht on, but gear doesn't work. I used this Ecu on another car, but there is the same problem, so i'm sure that is a ECU problem. Have you or someone of you a flash file? i hope in an help. thanks in advance.

    Hello, I'm new here,

    while searching for my solution to the problem, I came across this chat.


    My problem. After I had adjusted my 355 F1 over winter and wanted to start again in the spring, the engine could no longer be started. "N" flashes in the display and the indicator light for the circuit lights up red. As it stands, the TCU has been de-energized for too long and has been damaged as a result. The controlled sensors work.

    At the moment I am looking for an address that can repair the TCU CFC-101 for me.


    Can anyone help me with this?

    Hallo have a question:

    the 360 TCU, what is the Baudrate from this ? i tryed all... 5, 10, 12,5, 16, 20, 25, 50, 100, 125, 250, 500 - no answere on the table from this module.

    i connected on the big connectors + (1) and minus (27), and CAN lines 12P B and V, connector 45 and 33. the WHB about this diagram is really an italian desaster...

    what is the contact S154P and S152P ? how i see this it goes to the dash. maybe it also need + and minus ?

    Thanks for your help

    This is the 348/355 forum ;)

    But to answer one of your questions...

    I've circled (in red) the splices S154P/S152P on this (very) complicated 360 wiring diagram:

    https://www.dropbox.com/t/iigl79zE6XXCEXHt

    The splices connect the CAN Bus wiring to the ABS ECU, the instrument panel and pins 12 and 29 of the RH Motronic ECU connector 1L. Note the load resistor in the circuit.

    Disregard my last post. I assumed you were looking for the splices that were attached to the F1 TCU plug (12P). These are numbered differently from the ones you mentioned. Standby.... I'll check my other wiring diagrams.

    when i look in the WHB the TCU Connector 10P with 52 Pins i am speak about.

    CAN is 12 P= Pinns 45 and 32 (B and V)

    Power Supply is only 1 + and 27 - ? and the big connectors 2 and 28 with S154P and S152P is fpr what ?

    Pin 2 is an earth and pin 27 is live battery power. 28 is ignition key power. It's probably also needed.
    Regarding ignition key power... Splice S69C (attached to pin 1 of connector 6D/1P) is shown in the first diagram I posted (top RH corner)

    But were they winning at the time the 360 was being built?


    (EDIT: Sorry for the thread creep, folks)

    because Schumacher was bring all his team from Benneton. you have ever been in Schumacher Museum in Klogn in Germany ? You can see what development Ferrari did, when Schumacher changed all with his Ingenieurs and the team principal. This season in F1 is again a shame for Ferrari.

    As Ferrari Fan i got serious and with the age i see this car manufactur very different. When 2026 will Audi be in F1 , my prediction: so long Audi will be in the F1, Ferrari will be NEVER again F1 Champion.

    My 360 is a souvenier because i am Schumacher Fan. was a great time. Todays F. cars: what a ****. Not one is a "Dream" like the Enzo (car) for example. i repair cars... all what i see about Ferrari: they only copy all. So many parts, all copyed. Key from fob from ford, the key from Audi 100, break zylinder Bosch from VW Bora...

    2024, at best Ferrari stay in Maranello. All the money what the F1 cost is wasted money for them. Last year: the 4th wheel at the pit stop was missing.. LeClerc 5 Laps before race ends. catched in for another Pit stop. 2nd place was not good enough... the 6th place was more ideal. Its not a professional team Ferrari in the 21st century in racing sport. i am very unhappy that i need to say all this.

    About the Purosangue... i have NO WORDS. Luca de Montezemolo what he sayed: so long i manage here all, we will NOT build a car with 4 doors. now they produce totally trash
