Description

ECS007IZ

●

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 P (Park) to any other position
unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from P to any other position.
The key cannot be removed unless the selector lever is placed in P.

●

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, respectively.
