- Preconditions:
- (ACC or IGN1) & (any door open or trunk open)
- Event:
The last opened door is closed
- SMK action:
SMK searches for a SMART KEY FOB in the interior.
- If no valid SMART KEY FOB is found, the SMK activates external buzzer and also sends ID OUT warning via CAN (exterior buzzer warning and internal buzzer warning).
- If a door is opened and closed again during terminals on and inside valid fob, SMK re-enables the authentication and stops the warning. If the terminal is in ACC, SMK shall turn on immobilizer lamp.
