    Tesla Model Y 2024 R7F701330

    Hi

    At the workshop we have a Tesla model Y airbag ecu to remove crash data from. This controller is locked (R7F701330) and I am Airbag service tool Pro user. I have a few question with regards to the soldering pads on this ecu can any one pinpoint where these are please on the picture I provided?

    From watching the videos is it also OK to partially remove capacitors from one of its pads or completely remove them? My P8 & GND are aslo less than 5cm and I will use 12v and additional GND from smart prog adapter. When I attempting to read should the ECU be top side up?

    My bench read is below:-

    You should remove the capacitors marked with red squares and solder them back after data Writing Data is complete.
    If connected correctly, the SRS unit can be in any position.

            Hi

            I ended up using the pinout posted below, all went well on the bench, read clear and write. Replaced all elements and tested on bench no crash.

            We install in car and again light went out, but after a test drive the light came back and other associated errors. Now on the bench again I have U3000:49 AD. I check all capacitors they are on fine and no issues on mcu either.

            Am a little confused, is there anything else I could try, all logs also posted below.

              U3000:49-AD means there is some hardware problem, check all soldering and clean the board.
              In most cases this is a short circuit on the MCU or Bosch driver.

                ok I will set up my microscope and take a closer look,

                thanks

                  After looking at the board thru my digital microscope, i was not able to find any issues like short cuircuit etc etc

                  In the end i started the operation again and wrote the clear file i saved. I lost another token but all seems ok on the bench.

                  Lets see what happens when it goes into the car
