Above a ground speed of approx. 8 km/h the R/P locking solenoid (89) is actuated by the electronic selector lever module control unit (N15/5). The rocker arm (102) presses on the rocker (100), which is turned to the locking position.

The lock lever (69) rests against the rocker (100) and the selector lever (80) cannot be shifted to position "R".

P lock, function

The selector lever position "P" is locked whenever the R/P locking solenoid (89) is not actuated by the electronic selector lever module control unit (N15/5). The prerequisites for this are as follows:

No voltage supply to the electronic selector lever module control unit (N15/5)
Brake pedal not pressed

Under these conditions the rocker (100) is held in front of the locking lever (69) by the spring force of the leaf spring of the rocker(101). It is not possible to shift the selector lever (80) out of selector lever position "P". The R/P locking solenoid (89) is actuated with "circuit 15 ON" and when the brake pedal is pressed. The rocker arm (102) presses on the rocker (100); the selector lever (80) can be shifted out of selector lever position "P".
