    Hi — I’m diagnosing a 2013 Ferrari California that won’t go into gear.

    What I’m seeing:
    • On my scan tool (carsoft FR3.0) , Hydraulic System Pressure in the F1/TCM module reads N/A.
    • The car stays in N/P and won’t select R or 1.
    • When I switch ignition ON, I don’t hear the F1 pump prime (no 5-second whirr at the rear of the car that i am told by ChatGPT i should hear if thats correct - just the fuel pump priming).
    • I originally thought I’d found the pump (the RAPA unit in the left-rear boot area) but now realise that’s the roof pump.
    • I haven’t yet located or tested the actual F1 gearbox pump feed for voltage.

    Could you tell me:

    1. Exactly where the F1 gearbox hydraulic pump is located on the California — left or right side, and is it visible from the wheel arch or only from underneath?

    2. Where are the fuses and relay that supply that pump?

    3. Does the TCM ever inhibit pump activation (e.g. when the pressure sensor is unplugged or after a low-voltage event), or should it always power the pump at key-on?

      My car is RHD but ill happily check both sides if i know what to do!
    Goal:
    Find the correct pump and its power feed so I can check for 12 V at the connector, confirm if the pump itself or its fuse/relay is the cause, and restore hydraulic pressure (≈ 50 bar).

    You have a DCT, not an F1 system.
