A/T SHIFT LOCK SYSTEMPFP:34950
DescriptionACS002RT

The mechanical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, the selector lever cannot be shifted from “P” position to any other
position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” position to any other position.
The key cannot be removed unless the selector lever is placed in “P” position.

The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside the key cylinder.
