P1690 Immobilizer-Smartra No Response - General Information

Component Location





General Description

1. The sequences of the PIN code storage are as follows.
(1) Input the PIN code into the scanner when key teaching process.
The scanner transmits the Encrypted Code to the ECM after converting the PIN code into Encrypted Code.
(2) When the ECM gets the first key learning command,
it transmits the SMARTRA 3 learnt command and Encrypted Code to the SMARTRA 3
(3) If the SMARTRA 3 statue is virgin/neutral, the SMARTRA 3 stores Encrypted Code in EEPROM and transmits the success message of the Encrypted Code storage.
(If the SMARTRA 3 is learnt, the SMARTRA 3 compares Encrypted Code transmitted by the ECM with Encrypted Code stored in EEPROM and transmits the (in) correct Encrypted Code message to ECM)
(4) If the SMARTRA 3 is learnted normally or the Encrypted Code of the registered SMARTRA 3 is the same as the 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 SMARTRA 3 learning :
(1) starts with EMS request of PIN from scanner through the key teaching procedure.
(2) is possible in case that the status of SMARTRA is "virgin" or "neutral".
(3) In case that the SMARTRA 3 is "learnt", the SMARTRA 3 will transmits the information if PIN inputted from scanner is same as the PIN in SMARTRA 3.
(4) is possible regardless of key status.
3. The sequence of the SMARTRA 3 confirms are as follows.
(1) After communication with the SMARTRA 3, the ECM transmits the random number with requirement of the TP ID information.
(2) The SMARTRA 3 encrypts 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 SMARTRA 3 with the result calculated by ECM.
And If result are coincided with each other; the ECS concludes the valid confirmation of the SMARTRA 3.

DTC Description

The ECM sets DTC P1690 if there's No Response from SMARTRA.
