Steering Column Lock Indication
WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
The instrument cluster monitors the key-in-ignition status, the ignition switch position status, and the steering column lock status. When the key is in the ignition switch, the ignition switch is in the RUN position and the steering column is locked, the instrument cluster turns on the steering column lock warning indicator. The steering column lock status is sent to the instrument cluster from the steering column lock module over the communication network.
