Key Locking Function

The key locking function is only active on vehicles with automatic transmission. The TCM control unit transmits the current selector lever position to the SCCM control unit via the HS CAN. If the current selector lever position is P, the SCCM deactivates the key lock and the ignition key can be removed.
