    I have had multiple intermittent rear lamp failures ( brake and signal) on both sides of my Roma that show up as error messages on the dash, including rapid blinking of the dash turn indicator. But they always go away. I even had the head tech from Ferrari Quebec sit in the car and he saw the rapid blinking and then error disappeared while he was in the car. Some kind of voodoo magic.

    I that why you want the diagram?

    I’ve seen it many times as well it is the first sign your battery is slowly going bad.

    Are you using the Ferrari battery tender (POS) or a CTEK charger/conditioner?

    The car is brought from USA to EU. The rear lamps were converted to have yellow blinkers. Everything was coded. But now there is one failure- only when you hit stop pedal, stop and turn light are switching together. In other situations everything is correct.
    Also, first time coding before it was that position light with blinker. So I wanted to check the wirings and maybe find other solution for my problem

    Ok, if anyone will ever look for the BCM: it is on the driver side behind steering wheel trim at the bottom. And I made changes in cables using electrical diagram for AR Stelvio 2022, the body computer is totally the same, the cable colours and pin numbers also.
