Location
The parking lock interlock mechanism connects the selector lever of the floor selector with the electronic ignition/starter switch control module (N73).

Task
To prevent the transmitter key (A8/1) being removed when selector lever position < P > is not engaged.

Design
The selector ever of the floor selector is connected to the electronic ignition/starter switch control module (N73) via the ignition lock control cable (53).

Function
When the parking lock is not engaged (selector lever position < D >, < R >, < N >) the shift and locking valve (60) locks the locking cam (61). The pressure spring (62) only pulls the shift and locking valve (60) off the locking cam (61) in selector lever position < P >. The transmitter key (A8/1) can now be turned and removed in position < O >.
