Dynamic Stability Control (DSC III version 5.3) was introduced on the 1998 Model Year E38 and E39 - 540 vehicles. For Model Year 1999, the system is enhanced with additional control functions and a new combined rotational rate/lateral acceleration sensor as version 5.7.

It continues to be offered as standard equipment in the E38 and E39 - 540 models. The new functions are titled as the Dynamic Braking System and include the:

• Dynamic Brake Control (DBC)

The DSC III 5.3 system for the E38 and E39 is supplied by Bosch and the complete system operation is covered in the 1997 Model year Update - Part Two training manual. The new functions of operation of the DSC III 5.7 system will be covered in this training manual.

Dynamic Stability Control (DSC III) is also being introduced for the E46 vehicles as optional equipment. This system is supplied by ITT Teves, however many of the system components and features are similar to the Bosch system. The full function description and operation of the Teves system will be covered in this training manual.
