Shift Lock Control

The shift lock system prevents the shift lever from mis-shifting. The shift lock solenoid is normally OFF. After starting the engine in P, the shift lever cannot move to any other position from P because the shift lock stop stops the lock pin unless certain conditions are met. When the brake pedal is pressed and the accelerator pedal is not pressed, the PCM commands the shift lock solenoid is ON; the shift lock solenoid plunger in the shift lock solenoid pulls the shift lock stop to release the lock pin. Pressing the shift lever button allows the shift lever to move to any other position. When the brake pedal and the accelerator pedal are pressed at the same time, the PCM commands the solenoid OFF and the shift lock system is locked.

When the shift lock system does not operate due to mechanical or electrical problem, you can unlock the shift lock temporarily by inserting the ignition key into the shift lock release hole and pressing the shift lock release. When the shift lock release end is pressed, the shift lock stop releases the lock pin, and the shift lever can move to any other position.
