Brake Interlock System

Brake Interlock System





This system is so designed that selector lever (4) cannot be shifted from "P" range position unless the ignition switch (1) is turned to "ON" and brake pedal (3) is depressed. Also, ignition key cannot be pulled out of key hole unless selector lever is in "P". These mechanism are as follows.

Steering Lock








When selector lever is in position other than "P", lock lever (5) interrupts key cylinder to turn to "LOCK" position, thus steering is kept to be operated free. However, when selector lever is shifted in "P", lock lever is released, thus allowing ignition key (1) to be removed and then steering is locked.

Shift Lock Solenoid





^ When the selector lever (1) is in "P" range, the ignition key position is "ON" and depressing the brake pedal cause the electric current to flow to the solenoid (2). As the lock plate (4) is drawn toward the solenoid in this state, it frees the detent pin (3), which then allows the selector lever to be shifted from "P" range to any other position.





^ Even when the selector lever (1) is in "P" range, if the ignition key position is "LOCK" or "ACC" or the brake pedal is not depressed, the electric current does not flow to the solenoid (2). In this state, the lock plate (4) is pushed away from the solenoid by spring force and it obstructs the detent pin (3) movement. Thus the selector lever button does not work even when pressed and the selector lever shift is prevented.

Manual Release Procedure for Shift Lock Solenoid
Shift lock solenoid can be manually released by the following procedure.





1. Remove access hole cover (1) by unfastening screw (2).
2. Turn ignition key to "ACC" position and move lock plate (3) toward front side of vehicle by using screwdriver or the like until detent pin (4) becomes free.
3. In this state, selector lever can be moved to any range or position regardless of brake pedal operation.
