Component Inspection

WARNING: This page is about a different car, the 2020 Hyundai Santa Fe. However, it is still accessible from the selected car via links, so may be relevant.

IBU (SMK + BCM + TPMS) Inspection

  1. Neutralize the IBU (SMK + BCM + TPMS) using GDS.
  2. Perform the key teaching procedure for the ECM after neutralizing the ECM.
    CAUTION: Pin code must be prepared to neutralize the IBU (SMK + BCM + TPMS) and to perform key teaching procedure.
  3. Is the neutralization of the IBU (SMK + BCM + TPMS) and the ECM and key teaching properly completed?

    YES 

    • The fault can be intermittent, caused by poor contact of connectors between the IBU (SMK + BCM + TPMS) and the ECM. Or the ECM's memory was not cleared after repair. Thoroughly check connectors for looseness, poor contact, bending, corrosion, contamination, deterioration, or damage. Repair or replace relevant component as necessary and then go to "VERIFICATION OF VEHICLE REPAIR ".

    NO 

    • Replace the IBU (SMK + BCM + TPMS) with an working test sample and check for proper operation. If it works properly, put the new IBU (SMK + BCM + TPMS) in place. Then, go to "VERIFICATION OF VEHICLE REPAIR ".
NOTE:
  • PIN code will be stored in the IBU (SMK + BCM + TPMS), ECM, and FOB.
    1. If the IBU (SMK + BCM + TPMS) is registered, the key teaching process cannot be proceeded.
    2. PIN number can be registered by neutralizing the IBU (SMK + BCM + TPMS)
    3. The engine ECM can be neutralized using the GDS. (Enter the PIN code)
    4. If a virgin engine ECM is installed on the vehicle, the VIN will be automatically encrypted by the IBU (SMK + BCM + TPMS).
    5. Registering PIN code is only possible when the component is virgin or in the neutralized state.
  • All Learning procedure can be done with a GDS while the ignition switch is off.
    • IBU (SMK + BCM + TPMS) Learning
      1. Before the learning procedure for FOB Key, or begins, the Smart Key unit should have a registered PIN code first.
      2. In case of replacing the IBU (SMK + BCM + TPMS), all of the new keys should be registered first and then re-perform the learning procedure for the rest of the keys.
      3. When a wrong PIN is entered to the IBU (SMK + BCM + TPMS) 3 times, neutralization and teaching procedure will not be allowed for 1 hour.
      4. If the battery is discharged during neutralization or teaching procedure, timer will start again from the beginning. Therefore, one must wait for 1 hour.
