    Hello everyone! I am an owner of a 2002 360 Modena for about two years now. just recently took it to a body shop for some minor body work to the rear bumper. the vehicle was at the shop for about two months and within in that time i believe that the battery maybe have died (asked the manager at the body shop and he had denied the battery every dying). after picking up my vehicle on the completion date i didn't really notice anything wrong with it and it had started just fine. after i had left the shop the first thing i noticed was the turn signals were not working when i was driving the vehicle, so i decided to drive it straight home. when i got to my house i parked the vehicle in the garage and turned it off and when i did that i noticed that the radio didn't turn off with the vehicle as it normally should and i had to manually press the power button on the radio to turn it off, as i got out of the vehicle i closed the door and tried to lock it with me key fob but the car would just beep without locking or unlocking the doors, i just left it as is. i noticed my California registration is due and i also have to take it in for emissions smog inspection, so i took it to a smog stations and had them do a pre-test first and they had told me that my on board diagnostic computer had been reset (which i have no clue of doing) and it usually happens when some one disconnects and resets the battery and that i would have to drive it close to about 100 miles to complete the obd readiness monitors. i am thinking that the car battery had died while it was in the body shop and they didn't use recommended procedures to charge the battery. if anyone has any knowledge about what is going on with my vehicle i would really appreciate the help. thank you!

    The battery power probably was off for a period and hence the smog fail. It would be quite routine to kill power when carrying out maintenance procedures on any car.

    What might have happened is the battery went dead and they might have jump started it and that might have caused problems.

    It I were you I would disconnect the battery and give it a minimum 24 hours on charge and then try everything again. All your problems might disappear.

    When you restart you should turn ignition on but not crank the engine for 15 seconds or so. You should then start the engine with all electrics off and just let it idle for about 15 minutes before you drive it or turn it off.

    Hopefully everything will be fine after the above. If not, report back.

    You should also get yourself an OBD code reader and software. At least that way you will be able to monitor your smog readiness yourself and save Ny further fruitless trips to the test centre.

    2 months for a "minor" repair??? As stated turn off the master, charge the battery. Ferraris are very very sensitive to low voltage which is probably what you have.

    I agree with Alan and Greg. Those are symptoms of battery being dead for an extended period of time.

    Check to see if your battery will still take a full charge and hold the charge. If not, time for a new battery. Replacement battery is around $250.00 and you can do a search here. Odyssey, Optima, Interstate, are very good replacements.

    Like Alan said these cars are very sensitive to low, unstable power that powers all the electronics.

    Hope that helps

    You only have one Immobiliser ECU. The other is an Immobiliser Interface Unit. One of the functions of the Interface Unit is to confuse thieves … All the wires going to it are black.

    The Immo ECU talks to the RH Engine Motronics ECU via the Interface Unit.

    There is no Immo bypass plug per se. You can, however, bypass the F1 TCU control over the starter relay via plug 8H. The Immo ECU sends an OK to start signal to the F1 TCU. The F1 TCU then looks at its start (cranking) prerequisites and if they are ok, it provides an earth for the starter relay coil. I don’t know if the signal going from the immobiliser system to the F1 TCU is an earth, a voltage or a coded signal.

    For future reference:

    From recent discoveries, it looks like the signal going from the Immo ECU to the F1 system interface plug “8H” ends at plug 8H. There is no wire on the other side of the plug. The Immo signal never reaches the F1 TCU.

    It seems that the Immo ECU signal is only used on gated cars. That is, the Immo ECU cannot affect cranking on an F1 car, only on a gated car. On an F1 car, only the F1 TCU can prevent cranking.

    On a gated car, the Immo ECU provides a ground for the starter relay coil.
