    Default SAAB 93 1.9DIT(AT) Engine stop after shift change

    Hi guys,

    Engine stop in few seconds after change gear to "D" (only D), but communication between modules ecu/abs/esp/cim is lost at once

    DTC
    - Ecu: no communication with abs/cim
    - Cim: no communication with ecu
    Etc...
    Any ideas?

    I assume this is a six speed aisin warner transmission and from your description the engine
    rev's drop only in the drive position. do you have a scanner where you can
    read live data
