Function Of P Lock 

The selector lever position "P" is locked whenever R/P locking solenoid (89) is not actuated by the electronic selector lever module control module (N15/5). See Fig 2. The prerequisites for this are as follows:

1. No voltage supply to the electronic selector lever module control module (N15/5).
2. Brake pedal not depressed.

Under these conditions the locking lever (90) is in the locking position (P-lock).

The web on the locking lever (P-lock) (90b) locks the locking disc (69). It is not possible to shift the selector lever (80) out of selector lever position "P".
