    So, when I got my SD2 I started this thread in the 355 section:

    https://www.ferrarichat.com/forum/threads/learning-using-and-documenting-the-use-of-an-sd2-on-a-355.554993/

    My local friend Bruce (GTS Bruce) has a 575M and a few weeks back I used the SD2 to set the type of tires he has in the TPMS. This setting sets the baseline tire pressure.

    Made the proper selection and cleared the faults - the car has been fine since (for that issue).

    Bruce called again recently with a suspension fault. Connected the SD2 to find the RH vertical acceleration sensor fault. Clear the fault, it came back. So, we know it's 1 of 3:

    - Bad sensor
    - Bad ECU
    - Bad wiring

    Last night I had intended to swap L and R to see if the problem moved. Well, probably an hour work of work. The sensor is not hard to get to but by the time cables are routed, etc, the time would add up. The parts not very expensive so I ordered a part for Bruce.

    Without the SD2, this would be very hard to find.

    These tools are very valuable, :) and expensive :D

    Will update once resolved.

    My pleasure, Bill. I'm a blind man with this tool. Zero documentation out there so I'm learning as I go. I'm fortunate to be friends with a great factory tech down in Miami (Matt Burns) and he guides me when he can. I know other techs that help out too but Matt knows this stuff like the back of his hand.

    Dave,

    There is zero information on how the 550 fuel cooling system works. In a nutshell freon from HVAC run through an heat exchanger kinda like the trans oil/coolant heat exchanger in the 360. Then there must be a temp sensor somewhere to open something like an orifice valve when the fuel gets hot. With the SD can you gleen any information of that system?

    Carl, if I have time when I work on Bruce's car next week, I will try to connect to every ECU and create screen shots of all pages. If I don't have time next week, I can do it over winter as Bruce lives a mile from my shop. He will supply the drinks :)

    No fuel cooling on 575s, so nothing to check. Returnless system.

    Dave ask Matt, he changed the TPMS on my 575 very recently and I havent had any issues at all. Call the guru. That 575 in the pic has the exact same spec as mine too from the seats thats awesome. Also FWIW not sure if your client cares but matt got me a bluetooth to work with the factory radio, its behind it and i can now play music from my iphone in the 575 which was a pretty sweet feature not available in 2002 haha. He can tell you about that too if the client cares for it, i love it for the long trips.

    You might have missed it but I did ask Matt - the TPMS error was fixed weeks ago. We are now awaiting a new acceleration sensor to install which I expect tomorrow.

    I check the radio etc at least once a year to see if it works. The music I prefer is windows down open pipes in the 575. My daily driver a tacoma pu truck has all that sat etc stuff to play with and listen to.
