collating a first ID code received from the portable device with an ID code stored in the in-vehicle unit when an engine start
command is issued by the user;
permitting starting of the engine when the first ID code matches the stored ID code; and
permitting starting of the engine in response to the engine stall stored in the in-vehicle unit irrespective of collation
of the first ID code with the stored ID code.
