Smart key controller role
An electronic key computer participates in recognizing an authorized key and coordinating vehicle access and starting authorization. In a smart key system, this can support functions such as unlocking a door when the key is nearby and allowing the vehicle to start without inserting a conventional key.
The complete identifier distinguishes this calibration from other files in the 89983 family. The identifier alone does not establish the exact vehicle application, key-system configuration, or a change made by this particular revision. No stock or modified variant is identified in the filename.
