Shift Interlock: Description and Operation

GENERAL




To increase safety during "standing start", a shift lock system is utilized to prevent shifting of the selector lever from "P" to any other position unless the brake pedal is depressed. This system is also provided with a key interlock which prevents removal of the ignition key from the key cylinder unless the selector lever is set at "P".


SHIFT LOCK SYSTEM




The selector lever can be moved from "P" to any other position in the following cases:
- The brake pedal is depressed with the ignition key set at "ON" or "START". The ignition key can be rotated from the "ACC" to the "LOCK" position and then removed from its key cylinder only when the selector lever is set at "P".


KEY INTERLOCK




When the selector lever is set at any position other than "P", the solenoid pin is ready for operation so that the interlock lever comes in contact with the rotator which turns together with the key plate. Thus, the ignition key is prevented from rotating up to the "LOCK" position.





When the selector lever is moved to "P", P position switch in the selector lever assembly turned ON, and the solenoid pin moves to the release position so that the lever spring disengages the interlock lever from the rotator's stopper. As a result, the key plate can be rotated to the "LOCK" position. The key plate can be inserted into or removed from the "LOCK" position only.
