PROCEDURE


  1. GPF DEPOSITION VALUES (w/ GPF)

    Note

    Before replacing the ECM, store the volumes of accumulated ash (metal oxide) and PM (Particulate Matter). After replacing the ECM, write the volumes of accumulated ash and PM to the new ECM. (w/ Gasoline Particulate Filter)

  2. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

    Note

    When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
