Check Smart Key PCM/ECM Inspection

IG KEY "ON" & Engine "OFF".
Neutralize smart key PCM/ECM with GDS.
Perform key teaching procedure for smart key PCM/ECM with GDS.
CAUTION: Pin code must be prepared to Neutralize Smart Key PCM/ECM and to perform key teaching procedure
Is the neutralization of Smart Key PCM/ECM, Engine PCM/ECM and key teaching normal?
YES
- Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- If the problem is corrected, replace Smart Key PCM/ECM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NOTE:
- PIN code is programmed in Smart key PCM/ECM, Transponder.
  1. If the Smart key PCM/ECM is not registered with PIN, key teaching process is not proceeded.
  2. Registering PIN is available after Smart Key PCM/ECM is neutralized.
  3. Neutralization of Engine PCM/ECM is available with GDS (Registering PIN code)
  4. If the virgin engine PCM/ECM is installed on vehicle, Engine PCM/ECM is automatically programmed PIN code by Smart Key PCM/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 PCM/ECM Learning
    
    Before learning procedure for Smart Key PCM/ECM should be registered PIN code first.
    
    In case of replacing Smart Key PCM/ECM, All of the keys should be newly registered again.
    
    In case that Smart Key PCM/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.
