Electrical Emergency Program




Electrical Emergency Program

The electrical emergency program shifts the transmission into 5th or 3rd gear (speed and previous gear dependent) after a CAN bus failure. After restarting the engine, 3rd gear is engaged when selecting position D. After a CAN bus failure, positions P, R, N and D are selected via a separate serial line (hardwire).


CAUTION: The Shiftlock function is also deactivated, making it is possible to engage a gear without pressing the brake pedal. This is also indicated by a Check Control message.


When KL15 is switched "OFF", position P will be engaged immediately at speeds below 2 km/h. This is because the "key inserted/key not inserted" signal is not detected. The N-hold function is not possible with "engine off" (Caution in car wash systems).

The instrument cluster can not detect a position change. The position indicator in the instrument cluster is blanked out. The shift pattern with R, N, D remains and the arrows will flash.
