Do not place the card key in the vehicle when starting the
engine with the valid key, otherwise programming cannot be
performed. If the engine is started with the card key, remove the
card key from the vehicle after the engine is started.
Although the security light starts flashing and DTC 15 is displayed
after approx. 1 min, this does not indicate an improper procedure.
Continue to perform the procedure as indicated.
