CABLE, Park Lock
DESCRIPTION
DESCRIPTION
The Parking Key Interlock system prevents the driver from shifting out of Park when the key is removed from the ignition cylinder, and prevents key removal unless the shifter has been returned to Park.
OPERATION
OPERATION
The interlock cable connects the lock housing and the ATX shifter. The shifter is locked until the key cylinder is rotated clockwise from the LOCK (1) position. Once the key cylinder is rotated out of LOCK (1), the shifter may be moved from Park. As the shifter moved from Park, the interlock cable is held at a position that prevents key removal.
