Smart Key Lamp Warning

As long as the preconditions are valid, the SMK ECU performs a periodical 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); periodical means, the search is done every 3 seconds.

If no Fob has been found, the SMK ECU starts Key out indicator lamp activation as all preconditions are valid and will perform another search 3 seconds later.

If any valid Fob has been found, the SMK ECU stops the Key out indicator lamp and will (if one door is open) perform another search 3 seconds later. If no door is open then it's only at the next when the preconditions are still valid, the search resumes by opening of one door.
