Shift Lock/Reverse Lock Mechanism

Shift Lock/Reverse Lock Mechanism
The shift lock system reduces the risk of unintentional engine starting. Starting the engine is possible only in the P and N positions. The shift lock system and the key interlock system make up the interlock control system. The key interlock mechanism is located in the steering lock assembly.

The shift lock mechanism consists of the shift lock solenoid, shift lock stop, shift lock release, and related parts. The reverse lock mechanism shares the shift lock solenoid with the shift lock mechanism. The reverse lock stop and the shift lock stop are interlocked with the shift lock solenoid operation. The shift lock solenoid is electronically controlled by these shift lock control system signals: brake pedal position switch signal, interlock control signal, and transmission range switch P position signal. If the shift lock solenoid does not operate, the shift lock/reverse lock mechanism can be released by pressing the shift lock release.





In the P position while pressing the brake pedal, the shift lock solenoid is turned ON, and the shift lock solenoid plunger is retracted to release the shift lock stop. This allows the shift lever to be moved.





When the brake pedal is released, the shift lock solenoid remains OFF, and the shift lock stop locks to block the shift lever in the P position.





When the shift lever is shifted to the R position from the D5 position and N position (under certain conditions), the shift lock solenoid is turned ON, and the shift lock solenoid plunger is retracted to release the reverse lock stop. This allows the shift lever to be moved to the R position.





If the conditions of turning ON the solenoid are not met, the shift lock solenoid remains OFF, and the reverse lock stop locks to block the shift lever in the N position.
