IG KEY "ON" & Engine "OFF".
Erase DTC after connecting GDS.
Check Smart key status in "Vehicle S/W management", if DTC is retrieved.

Is the smart Key ECM learnt?
YES
- Neutralize the PCM/ECM after erasing the DTC with GDS.
  Check that system is normal after checking the DTC again. (If the DTC is set again, replace PCM/ECM)
  
  Wait for more than 1 min. with IG ON so that smart key ECM register PIN into Engine ECM automatically.
NO
- Perform key teaching procedure after replacing PCM/ECM and then, go to "VERIFICATION OF VEHICLE REPAIR " Procedure.
NOTE:
- PIN code is programmed in Smart key ECM, Transponder.
  1. If the Smart key ECM is not registered with PIN, key teaching process is not proceeded.
  2. Registering PIN is available after Smart Key ECM is neutralized.
  3. Neutralization of Engine ECM is available with GDS (Registering PIN code).
  4. If the virgin engine ECM is installed on vehicle, Engine ECM is automatically programmed PIN code by Smart Key ECM.
  5. Registering PIN code is only possible for virgin or neutralized status.
- All Learning procedure is able to do with a scan tool in the vehicle's ignition key off state.
  - Smart Key ECM Learning
    
    Before learning procedure for FOB Key, Smart Key ECM should be registered PIN code first.
    
    In case of replacing Smart Key ECM, All of the keys should be newly registered again.
    
    In case that Smart Key ECM receives 3 times with wrong PIN, It is not allowed for neutralization and Key Teaching for 1 hour.
    
    If the battery is discharged during neutralization or Teaching, Timer will start again from beginning. Therefore, it is avoidable to wait for 1 hour.
  - ESCL Learning
    
    It is O.K for registering ESCL just one time. And, it is available for ESCL to neutralize and re-teach with same PIN code.
