Key Lockout Prevent Function

The lockout function observes the key switch signal input. If the input is ON (remote in the vehicle), the system will not lock the doors. If the driver manually locks and closes the doors with a remote in the vehicle (input ON), the MICU energizes the driver's door actuator and unlocks the driver's door.

When the trunk is closed with the remote left in the trunk, the RF unit detects the location of the remote and does not lock the trunk.
