    Hello. My car is a 2008 599GTB.

    Currently, the transmission failure warning light is on, and the car suddenly won't start.

    Image Unavailable, Please Login

    It's showing a P1755 code, and the car won't crank and start up.
    (It's displaying a "missing ignition activation relay driver.")

    I've replaced the battery and checked the starter motor.

    The gears 1st, N, and reverse all work, and when I test the gears, all 1st through 6th shift smoothly.

    Do you know how to fix this or can you help me?

    Thank you.

    Usually that is set when you have a low battery
