NISSAN ALMERA N16 2001 Electronic Repair Manual

DescriptionNJAT0102+The mechanical key interlock mechanism also operates as a shift lock:
With the key switch turned to ON, the selector lever cannot be shifted from ªPº (parking) to any other
position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from ªPº to any other position.
The key cannot be removed unless the selector lever is placed in ªPº.
+The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock
solenoid and by the operation of the rotator and slider located inside the key cylinder.
