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 either of the following cases:
- The brake pedal is depressed with the ignition key set at "ON" or "START".
- The shift lock release button is pressed due to current flow interruption or run-down battery. 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



1. Selector lever in any position other than "P"
(1) When the selector lever is moved to any position other than "P", the solenoid is energized to moves the solenoid rod to the operation position.
(2) The interlock lever, which is connected to the end of the solenoid rod, then moves the stopper in the direction of the rotator.
(3) 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.
(4) With the key in the "ACC" (key push) position, the key cylinder is held in that position by the stopper.

2. Selector lever in the "P" position
(1) When the selector lever is moved to "P", the solenoid is energized to moves the solenoid rod to the release position.
(2) The interlock lever, which is connected to the end of the solenoid rod, also moves so that the tension of the spring overcomes the stopper. The key will then be released (pushed).
(3) 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.




3. If the key plate is hard to remove, release the key interlock system by pressing the lock release button (located under the steering column cover). The key plate can then be removed.
