Function Of Gear Shift

WARNING: This page is about a different car, the 2004 Mercedes-Benz C230 and 2003 Mercedes-Benz C230. However, it is still accessible from the selected car via links, so may be relevant.

On transmission 722.6 the electrohydraulic control unit converts the electric signals going out from the electronic transmission control (EGS) into hydraulic signals.

Faults occurring in the ETC control unit (N15/3) are handled by the limp-home system. The limp-home system is designed so that the driver can reach a Service Operation even under extreme conditions.

Selector lever position "P", "R", "N" and "D" are transmitted by the electronic selector lever module control unit (N15/5) on the Controller Area Network bus class C (engine compartment) (CAN-C) and in parallel to this by means of a shift rod to the range selector lever at the transmission end. By touching or holding the selector lever towards "+" or "-" the shift range is pre-selected and displayed in the instrument cluster (A1) until an upshift of transmission 722.6 is possible.
