KIA | KDS 2.0 | Troubleshooting: Ethernet-Required ECU Upgrade Failure

Oscar Eom
Updated

This article provides troubleshooting procedures for Ethernet-required ECU Upgrade failures when using KDS 2.0 diagnostic devices. It covers possible causes, including incorrect tablet IP configuration, outdated software, and unstable connections. Corrective actions include checking the hardware, configuring IP settings, granting app permissions, updating the operating system, performing power resets, and contacting technical support if the issue persists.

Quick links

 

Applies to

Ethernet-required ECU Upgrade workflow using:

  • VCI2 + ECI (wired Ethernet connection)
  • VCI3 + 9-pin USB cable (Ethernet over USB)
  • KDS 2.0 diagnostic device and Android tablet

 

Symptom

 

Cause

  • Incorrect or missing fixed IP configuration on the tablet
  • Outdated Android OS or Google Play system update
  • Unstable VCI2/VCI3 power supply or incomplete connection
  • Temporary ECU or vehicle-side communication Stall requiring a power reset

 

Resolution

Step 1) Verify the Ethernet hardware connection

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

Confirm the connection method required for Ethernet upgrades:

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

    IMPORTANT:
    Make sure all connectors are fully seated and that the cables are not bent or damaged.

 

  • VCI3 + 9-pin USB cable: OBD → VCI3 → 9-pin USB → Tablet

    IMPORTANT:
    Make sure all connectors are fully seated and that the cables are not bent or damaged.

 

 

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

  • Tap the Recent apps button (□) on the Navigation bar.
  • Open the Android settings and navigate to:
    • Variant A: Settings → Connections → More connection settings → Ethernet → Configure Ethernet device
    • Variant B: Settings → Network & Internet → Ethernet → Configure Ethernet device

 

 

  • Enter the following static IP settings, and then 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 and Google Play system updates

 

A. App permission – GITMCommManagerService

When you perform an ECU Upgrade, KDS 2.0 prompts you to grant any required app permissions that are missing.
Make sure to tap [OK] or [Allow].

Manually granting app permissions for GITMCommManagerService:

B. Android OS and Google Play system update

  1. Open Settings on the tablet.
  2. Go to About tablet → Software information.
  3. Select Google Play system update.
  4. Make sure the tablet is fully updated. The minimum requirements are Android OS 13 and Google Play system update 2024 or later.

 

Step 4) If the ECU Upgrade still fails after completing Steps 1–3

Warning: Disconnect the vehicle battery only under safe working conditions and in accordance with the applicable service procedures.

  1. Disconnect the vehicle battery.
  2. Wait at least 5 Minutes for ALL ECUs to power down completely.
  3. Reconnect the battery, and then retry the ECU Upgrade process 2–3 times.

 

Step 5) If the symptom persists, restart the tablet

  1. Turn off the tablet completely.
  2. Wait approximately 10 Seconds.
  3. Turn on the tablet, and then attempt the upgrade again.

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

  • Check the IP address: 10.0.128.0 / Netmask: 255.0.0.0
  • Confirm the VCI wired Ethernet connection (VCI2+ECI or VCI3+9-pin USB)
  • Make sure all connectors are fully seated
FAIL(4900-99-9998)

Step 4) Reset the vehicle battery power

  • Disconnect the vehicle battery
  • Wait at least 5 Minutes for ALL ECUs to power down completely
  • Reconnect the battery and retry 2–3 times

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

  • Check the IP address: 10.0.128.0 / Netmask: 255.0.0.0
  • Confirm the VCI wired Ethernet connection (VCI2+ECI or VCI3+9-pin USB)
  • Make sure all connectors are fully seated
FAIL(7000-C8-0001)

Step 4) Reset the vehicle battery power

  • Disconnect the vehicle battery
  • Wait at least 5 Minutes for ALL ECUs to power down completely
  • Reconnect the battery and retry 2–3 times
FAIL(7000-13-0002)

Step 1) Reconnect the VCI at the OBD port

  • Disconnect the VCI from the OBD port
  • Wait a few Seconds
  • Firmly reconnect the VCI and retry the upgrade

Missing/deleted files – contact GIT America after verifying that the following files are present in the nvci/portableupdater folder:

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

Contact the ECU manufacturer or GIT America Technical Support

  • Provide the VIN, Event number, and Error code
  • The tablet app log may be required
  • The issue may involve ECU-specific conditions or firmware

 

If the issue persists

If Ethernet communication still does not start, the issue may be related to VCI firmware, ECI hardware, or specific vehicle conditions. Contact us and provide the following information:
