Similar to the construction discussed previously, a camshaft is provided at the end of the key cylinder rotor. This camshaft has a cam with the cut-out portion of its stroke from the ACC position to the ON or Start position. The lock pin is attached to the end of the parking lock cable and slides with the movement of the control lever mounted to the shift lever mechanism. The control lever is separate from the shift lock plate but is actuated by it.
Notice the crank ditch sloth in the shift lock plate. It is cut at an angle so that when the shift lock plate moves up or down, it causes the control lever to pivot at point B in the illustration below.
When the shift lever is in the Park position, the control lever rotates around B counterclockwise, pushing the parking lock cable so that the lock pin does not interfere with the camshaft. In this position, the key can be turned to the Lock position and removed.
When the shift lever is moved from the Park position, the lock plate is pushed downward by the shift lever button and the grooved pin. When the shift lock plate moves downward the control lever rotates clockwise, pulling the parking lock cable and lock pin into engagement with the camshaft. In this position, the key cannot be turned to the Lock position and removed from the ignition as seen in the following illustration.
