HYUNDAI | GDS Smart | Troubleshooting: Ethernet Required ECU Upgrade Failure

This article provides troubleshooting steps for Ethernet-required ECU Upgrade failures using GDS Smart diagnostic devices. It covers causes such as incorrect tablet IP configuration, outdated software, or unstable connections, and details resolutions including hardware checks, IP settings, app permissions, OS updates, power resets, and technical support contacts if issues persist.

Applies to

Ethernet‑required ECU Upgrade workflow using:

  • VCI2 + ECI (wired Ethernet path)
  • VCI3 + 19‑pin USB cable (Ethernet over USB)
  • GDS Smart diagnostic device and Android tablet

Symptom

Cause

  • Incorrect or missing tablet Fixed‑IP configuration
  • Outdated Android OS or Google Play System update
  • Unstable VCI2/VCI3 power or incomplete connection
  • Temporary ECU/vehicle-side communication stall requiring power reset

Resolution

Step 1) Verify correct Ethernet hardware connection

Note:
System or OS updates may reset manually configured Ethernet settings. Please verify and reconfigure the settings after an update if necessary

Confirm the exact connection method required for Ethernet upgrades:

  • VCI2 + ECI: OBD → ECI → VCI2 → Tablet

    PLEASE NOTE:
    Ensure all connectors are firmly seated and cables are not bent or damaged.

  • VCI3 + 19‑pin USB cable: OBD → VCI3 → 19‑pin USB → Tablet

    PLEASE NOTE:
    Ensure all connectors are firmly seated and cables are not bent or damaged.

Step 2) Verify static/fixed IP setting in tablet settings

  • Tap the Recent apps button (□) in the navigation bar.
  • Open Android settings and navigate:
    • Variant A: Settings → Connections → More connection settings → Ethernet → Configure Ethernet device
    • Variant B: Settings → Network & Internet → Ethernet → Configure Ethernet device
  • Set the following static IP and tap [Save]:
    • IP address: 10.0.128.0
    • Netmask: 255.0.0.0
    • DNS address: 8.8.8.8
    • Default gateway: 10.0.128.0
    • Proxy: None

Step 3) Confirm App permissions and Android OS & Google Play System update

A. App Permission – GITMCommManagerService

When you carry out an ECU Upgrade, GDS Smart asks for missing app permissions.
Please make sure to tap [OK] or [Allow].

Manual app (GITMCommManagerService) permission allowance:

B. Android OS & Google Play System update

  1. Open Settings on the tablet.
  2. Go to About tablet → Software information.
  3. Select Google Play system update.
  4. Ensure the tablet is fully updated (minimum: Android OS 13 + Google Play System 2024 or later).

Step 4) After completing Step 1–3, if ECU Upgrade still fails

Warning: Vehicle battery removal requires safe working conditions.

  1. Disconnect the vehicle battery.
  2. Wait at least 5 minutes for all ECUs to fully power down.
  3. Reconnect the battery and retry the ECU Upgrade process 2–3 times.

Step 5) If the symptom persists, reboot the tablet

  1. Turn off the tablet completely.
  2. Wait ~10 seconds.
  3. Turn it back on and attempt the upgrade again. 

Common Error Codes

Step 5) Reboot the tablet

  • Turn off the tablet completely
  • Wait ~10 seconds
  • Turn it back on and attempt the upgrade again
FAIL(4900-99-9997)

Step 2) Verify static/fixed IP setting + Step 1) Verify hardware connection

  • Check IP address: 10.0.128.0 / Netmask: 255.0.0.0
  • Confirm VCI wired Ethernet connection (VCI2+ECI or VCI3+19-pin USB)
  • Ensure all connectors are firmly seated
FAIL(4900-99-9998)

Step 4) Vehicle battery power reset

  • Disconnect the vehicle battery
  • Wait at least 5 minutes for all ECUs to fully power down
  • Reconnect the battery and retry 2–3 times
FAIL(7000-01-1010)

Step 2) Verify static/fixed IP setting + Step 1) Verify hardware connection

  • Check IP address: 10.0.128.0 / Netmask: 255.0.0.0
  • Confirm VCI wired Ethernet connection (VCI2+ECI or VCI3+19-pin USB)
  • Ensure all connectors are firmly seated
FAIL(7000-C8-0001)

Step 2) Verify static/fixed IP setting

  • IP address: 10.0.128.0
  • Netmask: 255.0.0.0
  • DNS address: 8.8.8.8
  • Default gateway: 10.0.128.0
  • Proxy: None
FAIL(7000-13-0002)

Step 1) Reconnect VCI at OBD port

  • Disconnect VCI from the OBD port
  • Wait a few seconds
  • Firmly reconnect and retry the upgrade
FAIL(5100-01-0001)

Missing/deleted files – contact GIT America after verify the following files exist in nvci/portableupdater folder:

  • procedure_pre_ota2_vec.xml
  • procedure_post_ota2_vec.xml
  • procedure_ucmInit_ota2_vec.xml
Other Error Codes

Contact ECU manufacturer or GIT America Technical Support

  • Provide VIN, Event number, and Error code
  • Tablet app log may be required
  • Issue may involve ECU-specific conditions or firmware

 

If it still doesn't work

If Ethernet communication still does not start, the issue may involve VCI firmware, ECI hardware, or specific vehicle conditions. Please contact GIT America with:
