This document describes the symptoms and causes of Ethernet-based ECU upgrade failures and provides step-by-step troubleshooting procedures, including hardware connection checks, static IP configuration, app permissions and OS updates, power resets, tablet restarts, error code-specific actions, and how to request additional support.

Applies To

ECU upgrades requiring Ethernet communication when using the following devices

  • VCI2 + ECI (wired Ethernet connection)
  • VCI3 + 19-pin USB cable (Ethernet over USB)
  • KDS 2.0 diagnostic device and Android tablet

Symptoms

Causes

  • Incorrect or missing static IP configuration on the tablet
  • Outdated Android OS or Google Play system update
  • Unstable VCI2/VCI3 power supply or incomplete connection
  • ECU or vehicle communication failure

Resolution

Step 1) Verify the equipment connections

Note:
Manually configured Ethernet settings may be reset during a system or OS update. After an update, verify the settings and reconfigure them if necessary.

Verify that the correct connection method is being used for the Ethernet-based ECU upgrade:

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

    Caution:
    Make sure all connectors are securely connected and that no cables are bent or damaged.

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

    Caution:
    Make sure all connectors are securely connected and that no cables are bent or damaged.

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

  • Tap the Recent Apps button (□) on the navigation bar.
  • Open Android Settings and navigate to one of the following paths:
    • Option A: Settings → Connections → More connection settings → Ethernet → Configure Ethernet device
    • Option B: Settings → Network & internet → Ethernet → Configure Ethernet device
  • Configure the static IP settings as follows, 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) Verify app permissions, the Android OS, and Google Play system updates

A. App permissions – GITMCommManagerService

When an ECU upgrade is performed, KDS 2.0 requests any required app permissions that have not yet been granted.
Make sure to select [OK] or [Allow].

How to manually grant permissions to the GITMCommManagerService app:

Required App Permissions for GLUV Logs and Wireless Connection Stability ⧉ 

B. Android OS & Google Play system updates

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

Step 4) If the ECU upgrade continues to fail after completing Steps 1–3

Warning: Disconnect the vehicle battery only in a safe working environment.

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

Step 5) Restart the tablet if the symptom persists

  1. Power off the tablet completely.
  2. Wait approximately 10 seconds.
  3. Power the tablet back on and retry the upgrade. 

Common Error Codes

Error Code Resolution
FAIL(4900-99-9996)

Step 5) Restart the tablet

  • Power off the tablet completely.
  • Wait approximately 10 seconds.
  • Power the tablet back on and retry the upgrade.
FAIL(4900-99-9997)

Step 2) Verify the static IP settings + Step 1) Verify the hardware connections

  • Verify the IP address: 10.0.128.0 / Netmask: 255.0.0.0
  • Verify the VCI wired Ethernet connection (VCI2+ECI or VCI3+19-pin USB).
  • Make sure all connectors are securely connected.
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.
FAIL(7000-01-1010)

Step 2) Verify the static IP settings + Step 1) Verify the hardware connections

  • Verify the IP address: 10.0.128.0 / Netmask: 255.0.0.0
  • Verify the VCI wired Ethernet connection (VCI2+ECI or VCI3+19-pin USB).
  • Make sure all connectors are securely connected.
FAIL(7000-C8-0001)

Step 2) Verify the static IP settings

  • 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 the VCI at the OBD port

  • Disconnect the VCI from the OBD port.
  • Wait a few seconds.
  • Reconnect it securely and retry the upgrade.
FAIL(5100-01-0001)

Missing/deleted files – Verify that the following files are present in the nvci/portableupdater folder, and then contact the GIT Customer Support Center:

  • procedure_pre_ota2_vec.xml
  • procedure_post_ota2_vec.xml
  • procedure_ucmInit_ota2_vec.xml
Other error codes

Contact the ECU manufacturer or the Kia Quality Department.

  • Provide the VIN, event number, and error code.
  • Tablet app logs may be required.

 

If the Issue Persists

If Ethernet communication still does not start, the issue may be related to the VCI firmware, ECI hardware, or a specific vehicle condition. Prepare the following information and contact the GIT Customer Support Center:
