Park Lock Solenoid

The park lock solenoid is a safety device that prevents an inadvertent shift out of Park when the key is in the OFF position. The key must be in the RUN position to release the park lock solenoid. The system consists of the park lock solenoid (integrated into the shift control assembly).

With the ignition switch in the ON position, voltage is supplied to the park lock solenoid. The park lock solenoid energizes through ground, unlocking the gearshift lever. With the ignition in the OFF or ACC position, the park lock solenoid de-energizes and locks the gearshift lever in the Park position.
