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