Key Memory
This feature provides the added convenience of identifying users of the vehicle whenever a lock or unlocked signal is generated via the individual FZV keys. A maximum of four FZV keys can be used with the Key Memory feature.
Each of the four keys generate a unique key identification signal (key number) that is transmitted simultaneously with the lock/unlock signals to the General Module. Key Memory does not respond to Lock/Unlock requests from the drivers door lock.
Most of the key memory functions require the vehicle be configured using the "KEY MEMORY" function of the DIS or GT-1. However, there are a few features that store settings automatically without configuration such as IHKA blower speed and temp setting. The key ID signal alerts the GM to communicate with select control systems over the K Bus to store (when locked) or reset (when unlocked) certain driver adjustable settings.
There are features that function as both a Car & Key Memory feature.
Example: the Automatic Seat Adjustment feature is encoded as a Car Memory Function with the following possibilities; when unlocking, when opening a door after unlocking, or not active at all.
If active, the seat positions are stored and reactivated by the Key Memory function for individual users of the car.
