Reverse/Park Lock, Function

P Lock, Function 

The selector lever position "P" is locked when the R/P-locking magnet (89) is not actuated by the electronic selector lever module control unit (N15/5). See Fig 1. The prerequisites for this are as follows:

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 position "P".

When the ignition is switched on and the brake pedal is depressed, the R/P locking solenoid is actuated. The rocker arm (102) presses on the rocker (100) and the selector lever (80) cam be moved away from position "P".

R Lock, Function 

Above a speed of approximately 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".
