Description
The selector lever cannot be shifted from "P" position to any other position unless the ignition switch is in the
ON position and the brake pedal is depressed.




Component Function Check
1. CHECK CVT SHIFT LOCK OPERATION
1. Turn ignition switch ON.
2. Move selector lever to "P" position.
3. Attempt to shift selector lever to any other position with brake pedal released.
Can selector lever be shifted to any other position?
YES - Go to SEE Diagnosis Procedure.
NO - GO TO 2.
2. CHECK CVT SHIFT LOCK OPERATION
Attempt to shift selector lever to any other position with brake pedal depressed.
Can the selector lever be shifted to any other position?
YES - Inspection End
NO - Go to SEE Diagnosis Procedure.
