Smart Key Reminder 2
- Preconditions:
- All terminals "OFF"
- Any door (including trunk) open
- No FOB-IN & no locking status (checked by SMK periodically for every 100 ms, as long as CAN/LIN is active)
- Vehicle action:
Closes the last door or trunk with knobs in locked state or with locking in progress
- SMK actions:
Checks the locking status for 500 ms after closing the door. If all doors are locked:
- IF NO FOB-IN ACTIVE
SMK searches for fobs in the interior of the vehicle.
The same LF-strategy is applied as it is defined for the ID out warning (registering only, no authentication).
- IF FOB-IN ACTIVE
SMK searches for valid TP.
If no fob has been found, no action is required.
If any valid fob has been found, SMK sends unlock command via CAN/LIN and activates ext. buzzer warning.
- IF NO FOB-IN ACTIVE
NO RELATED
