    I have checked there is voltage from battrey and ign, grounds all fine. managed to find 2 pair of CAN lines, and check voltages on both, voltages are also OK. one has 120 Ohms when disconnected, another is nothing,

    Scanner can not connnect ABS module, and when i disconnect abs plug and start car ABS light is coming on dash, connected and started car, ABS light is going off, It seems like ABS is communicating with some modules etc Engine, Instrument, but can not connect to scanner itself.,


    any wiring would be helpful to check 2nd line to find what is problem, 2 CAN lines could be used for scanning purposes, as I understand internal CAN lines working

    another thing is driving selector ( MANETTINO) stays in WET mode all the time, it is probably due to this ABS related issue,

    I had a very similar problem, however car would not start unless I unhooked and reconnected up battery. I would get all the same errors. I essentially was rebooting the system, which then allowed the car to start, but with these same problems. The car was on my battery tender. It was maddening. I finally set battery tender to “recondition” mode and that cleared up all my problems. I guess the battery output was insufficient.

    No no there is no problem with battrey, because of battrey abs could not be disappared from scan ecu's list. there is something else problem, - would be very good help if someone share abs wiring.

    Does car move? If the parking brake will not release you need a new EPB Module, do not do the manual release procedure, it will require new rear brake calipers (very expensive).

    car moves, and you can put on parking brake and relase parking brake, EPB Module is working and does not have a fault as well, when you on ignition ABS light gets on and after car start gets off from dashboard, but ESC, E-DIFF, AHV failure on dashboard comes up one by one,
    I can not connect to ABS module to determine what problem is,

    With Ferrari, error codes can have nothing to do with what is shown.

    Best to take it to a dealer for full diagnostics using their factory computers.

    Please post when you find the solution. I'm having the exact same issue with my car. All the failures you mentioned are the same exact ones i'm seeing on my dash. The manetino failure light temporarily came on and the car automatically went in wet mode. That light went away.

    Hi
    Actually car was fully waterfilled car, brought from Japan, I fixed all electronics and wiring from donor car. donor car was accident car.

    after I start car lots of faults were poping up etc ESC, E-DIFF, AHV failure and sport,race, mode was not activaing,
    i have driven some time, All faults has gone. Now there is only remaining AHV fault. automatic parking brake also working,

    on steering wheel monettino switch also working and changing modes, sport,race

    But stilll couln't connect to ABS ECU control unit, its might be due to Autel scanner, as it might not support this model 488..

    I was having the same issue with my 2015 California T. At random times I would get Manetino, ESC, and AHV failure. The car would run fine, but I had no ABS or traction control, which is not a great way to drive a Ferrari.

    I called the service advisor at Ferrari and he told me it was a battery issue, so I changed the battery and was still getting the faults. I then sent it in to service at the Ferrari dealer and he couldn't find any faults. I mentioned to him that I saw something on Ferrari Chat about a brake switch causing this problem and when they checked the computer it wasn't showing any brake switch faults. I had them change it anyway, and that took care of it. No more failures !

    P.S. I paid $6000 for the one year extended warranty, and the brake switch wasn't covered in that warranty !

    I am having the same issue with a 2018 GTC4Lusso T. I will be replacing the brake switch soon. The battery was just tested a few weeks ago.
