    Toyota-Subaru 98221CC061


    Hi all!
    After cleaning the 98221CC061 unit. The unit stopped detecting airbag errors!
    These errors were there before the crash was removed.

    The unit does not respond to disconnecting and connecting airbags

    I think that this block is cleaned differently by software. Because the unit itself is from Subaru and the car is Toyota
    I'm waiting for your help!
    Good luck!!

    The file looks good.
    Are you testing this on a car or on a bench?

      Оn a bench
      There should not be an error about unconnected airbags!

        Perhaps this SRS ECU needs an additional 12V power supply.
        ​But everything should be ok on the car.

          Okay, I'll test it on the car tomorrow and report the results!

              I have the same issues with this module, means is a clearing error. Exactly the same codes.

                  No, is not. Is not allowing you to clear codes on car.

                      Sir, read post above, I'm being doing this for years.

                      There is another post with the same issue after clearing crash.
                      Look on the forum.

                      These codes are not airbags failures.
                      Is related to the crash clearing data.
                      Even, with original data back, these codes now remain in the module system.

                      For me, could be MCU corrupted. Flash modification after clearing data.

                        You can write oryginal file for checking.

                          I did, and now I have the crash and these codes.
                          They are not going away. No matter what.

                            The problem in this post has been fixed, so just follow the instructions.
                            Install the SRS ECU on the car and run the diagnostics. You need to fix all active errors in the car, then run the "Clear Errors" function.

                              My god sometimes is so hard to work with you guys.
                              The scanner (Autel Maxisys Elite), does not allow you to erase the codes.
                              When you try to erase the codes, it says ECU is locked and does not allow erasing. Is a shame I dont have pictures. But those codes remain in the system. For me, is some corrupted data in the flash or soldering generate and damage to board, but these are exactly the same codes.
                              I tried 3 different times, and it did not work.
                              You can check my logs.
