GF27.10-P-2008GA Shift-lock, function
- TRANSMISSION 722.6


Function
The term shift lock combines the functions which, in addition to the parking brake, offer an additional safeguard for the vehicle to prevent it moving off unintentionally.

These include the functions of locking the selector lever position "P" and locking the ignition lock as well as the park pawl in the transmission.

The shift-lock only permits shifting out of selector lever position "P" when the transmitter key (A8/1) has been turned into position "ignition: ON" and the brake pedal is depressed. The vehicle is secured mechanically by blocking the park pawl gear.

In order to ensure that after parking the vehicle the selector lever is shifted into selector lever position "P", the transmitter key (A8/1) can only be turned towards "0" and removed from the electronic ignition switch control unit (N73) in this position (ignition lock locking function).

Simultaneously the function of locking selector lever position "P" serves as antitheft lockout. For this reason it is not possible to move the selector lever out of position P" in the event of failure of one of the following components:
^ EIS [EZS] control unit (N73)
^ Electronic selector lever module control unit (/)N15/5
^ Voltage
^ CAN data bus
^ Stop light switch (S9/1)
^ R/P locking solenoid
