Monitor GDS Data

WARNING: This page is about a different car, the 2016 Hyundai Elantra GT and 2015 Hyundai Elantra GT. However, it is still accessible from the selected car via links, so may be relevant.
  1. IG KEY "ON" & Engine "OFF".
  2. Erase DTC after connecting GDS.

  4. Is the Smart key ECM learnt status?

    YES 

    • Wait for 1 hour until ECM status is unlock with IG ON.

      After ECM status is unlock, perform the key teaching procedure. Finally, Proceed to: "VERIFICATION OF VEHICLE REPAIR " procedure.

    NO 

    • Fault is intermittent caused by poor contact in Smart Key ECM and/or ECM's connector or was resolved and Smart key ECM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Resolve or replace as necessary and then Proceed to: "VERIFICATION OF VEHICLE REPAIR " procedure.
    NOTE:
    • PIN code is programmed in Smart key ECM, Transponder, ESCL.
      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
        1. Before learning procedure for ESCL, Smart Key ECM should be registered PIN code first.
        2. In case of replacing Smart Key ECM, All of the keys should be newly registered again.
        3. In case that Smart Key ECM receives 3 times with wrong PIN, It is not allowed for neutralization and Key Teaching for 1 hour.
        4. 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
        1. It is OK for registering ESCL just one time. And, it is available for ESCL to neutralize and re-teach with same PIN code.
