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

TRANSMISSION 722.6 in MODEL 215, 220, 230, 240 

Operation 

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 parking lock in the transmission.

The shift lock function only permits shifting out of selector lever position "P" if the transmitter key (A8/1) has been turned to the 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" in this position and removed from the EZS control module (N73) (ignition lock locking, function).

At the same time the function locking of the selector lever position "P" serves as an anti-theft lock. For this reason it is not possible to move the selector lever out of position "P" in the event of the failure of one of the following components:

• for EIS control module (N73)
• Electronic selector lever module control module (N15/5)
• Voltage
• CAN data bus
• Stop light switch (S9/1)
• R/P locking solenoid
