Function of locking of selector lever position "P"
One of the functions of the shift lock is to lock the selector lever in position "P".
The selector lever is locked electronically. The selector remains disabled in position "P" if no approval is given by the drive authorization system or the brake is not operated or there is no power supply to the electronic selector lever module control unit (N15/5).

Upon receipt of a valid drive authorization code from the electronic ignition switch control unit (N73) via the Controller Area Network bus Class C (engine compartment) (CAN-C), the electronic selector lever module control unit (N15/5) actuates the R/P blocking magnets (89) when the brake pedal is pressed and therefore the stop lamp switch is actuated (S9/1). The signal from the stop lamp switch (S9/1) which has been operated is likewise conveyed to the electronic selector lever module control unit (N15/5) via CAN-C. The R/P locking magnet (89) releases the selector lever thus allowing the selector lever to be moved away from position "P".
