GF27.60-P-5164ACM Electronic transmission-control control unit, component description
- TRANSMISSION 722.643/649
- refinement package
- as of model year 09

Component Identification:

Location on model 230.479 with code (P99) Special model "AMG Black Series"
The electronic transmission control (EGS) control unit is located in the right rear of the engine compartment next to the ESP, SPS [PML] and BAS control unit.

Location except model 230.479 with code (P99) Special model "AMG Black Series"
The ETC [ETS] control unit EGS is located on the plate in the front passenger footwell.

Task
The tasks of the electronic transmission control (EGS) control unit are subdivided into the following partial tasks:
^ General
^ Input and output signals

General
The ETC [EGS] control unit determines the instantaneous operating condition of the vehicle and controls all gear change sequences taking into account shift comfort and the driving situation.

The electronic transmission control (EGS) control unit is flashable i.e. the complete software in the control unit can be changed (replaced).

Input and output signals

Signal inputs and outputs
