ECM, the ECM begins operation the Transponder Learning.
(5) If the learning of the first transponder,
the ECM stores the Encrypted Code in its EEPROM and converts state into learnt state.
2. The SMARTRA3 learning :
(1) starts with EMS request of PIN from scanner through the key teaching procedure.
(2) is possible in case that the status of SMARTAR is "virgin" or "neutral".
(3) In case that the SMARTRA3 is "learnt", the SMARTRA3 will transmits the information if PIN inputted from
scanner is same as the PIN in SMARTRA3.
(4) is possible regardless of key status.
3. The sequence of the SMARTRA3 confirms are as follows.
(1) After communication with the SMARTRA3, the ECM transmits the random number with requirement of the TP ID
information.
(2) The SMARTRA3 encryptes the random number and transmits the result(Encrypted Random Number) to the
ECM with TP ID information.
(3) The ECM compares the result transmitted from the SMARTRA3 with the result calculated by ECM.
And If result are coincided with each other; the ECS concludes the valid confirmation of the SMARTRA3.
